  • Use extreme care in handling fuel. It is flammable and its vapors are explosive.

  • Extinguish all cigarettes, cigars, pipes, and other sources of ignition.

  • Use only an approved fuel container.

  • Do not remove the fuel cap or fill the fuel tank while the engine is running or hot.

  • Do not add or drain fuel in an enclosed space.

  • Do not store the machine or fuel container where there is an open flame, spark, or pilot light, such as on a water heater or other appliance.

  • If you spill fuel, do not attempt to start the engine; avoid creating any source of ignition until the fuel vapors have dissipated.

Understanding Horizontal Directional Drilling

Horizontal directional drilling is a process used for drilling a horizontal bore through the soil and under obstructions such as roads, buildings, bodies of water, etc. Once you drill the bore, pull back the utility lines or pipes through the bore and connect them as needed. Because it does not require very much disturbance of the surface, installation of utilities using directional drilling preserves the environment and saves both time and money over traditional installation methods such as trenching.

When installing cabling or pipe using a directional drill, complete the following steps:

  1. Gather site information.

    Before operating in an area with high-voltage lines or cables, contact a “One-Call System Directory” service. In the USA, call 811 or your local utility company. If you do not know your local utility company’s phone number, call the national number (USA and Canada only) at 1-888-258-0808. In Australia, call 1100 for the nationwide marking service. Also, contact any utility companies that are not participants of the “One-Call System Directory” service. Please refer to Drilling Near Utility Lines for more information.

    Before fully planning the bore path, gather information about the job site such as the location of other utilities, obstacles at the site, and what regulations and permits you need to complete the job; refer to Gathering Site Information.

  2. Plan the bore path.

    Before drilling, plan the bore path based on the information you gathered. Refer to Planning the Bore Path.

  3. Prepare the job site and the machine.

    Before drilling, prepare the job site with an entry point, depth-gauge hole (optional), and an exit hole. Drive the machine to the job site, set it up for drilling, and connect it to a drilling-fluid mixer.

    Note: When drilling, connect the machine to a drilling-fluid mixer that mixes water with bentonite clay and other ingredients. The machine pumps this mixture, referred to as drilling fluid or “mud,” through the drill pipe and out of the drill bit. The drilling fluid lubricates the drill bit, helps to hold the bore open while drilling, and mixes with the spoils, flushing them out of the bore through the entry point.

    Refer to Preparing the Job Site and the Machine for instructions on preparing the job site and the machine.

  4. Drill the bore.

    Drill the bore in 3 stages:

    1. Entry

      In the entry phase of the bore, push the drill bit and head into the ground at an angle of up to 16 degrees. After pushing in one or more pipes, begin drilling down and forward until you reach the desired depth or depth-gauge hole (if used).

    2. Horizontal Reach

      After reaching the desired depth, push the bit forward, steering the bit to a horizontal depth. The sonde emits a radio signal from the sonde housing, allowing the locating-equipment operator on the surface to track the location and depth of the head using the sonde receiver as you drill and steer it along a planned path..

    3. Exit

      Once you have attained the planned horizontal reach, steer the head up at an angle, similar to your entry angle, bringing the bit into the exit hole or trench.

    Refer to Drilling the Bore.

  5. Backream the bore and pull back the cabling or pipe.

    After entering the exit hole, a crew member detaches the drill bit and sonde housing from the drill pipe. Attach a reaming bit and the end of the cable or pipe to be pulled through the bore. The reaming bit is designed to enlarge the bore as you pull it back. Pump drilling fluid through the pipe to the reaming bit as you pull the cable or pipe back through the bore to lubricate the reamer and allow the cable or pipe to slide easily through the bore. Continue pulling the pipe back until the reamer reaches the depth-gauge hole or exits at the entry point. Remove the reamer and product from the drill pipe, pulling the pipe the rest of the way back to the machine.

    Refer to Backreaming and Pullback for instructions on backreaming and pulling cable or pipe.

  6. Finish the bore and leave the job site.

    After completing the operation, disconnect and clean the machine, and load it on the trailer; refer to Finishing the Job.

Gathering Site Information

Planning the Initial Path

Before drilling, plan the path you will bore and prepare as follows:

  • Create a basic plan for the bore, mapping out the proposed path.

    • Note any obstacles which may affect the bore such as large trees, bodies of water, buildings, etc.

    • Plan the path of the bore to avoid as many obstacles as possible.

    • Determine the depth of any bodies of water to be crossed to ensure that you can get deep enough to go under them.

  • Determine the depth you need to install the material at and the minimum bend radius of both the drill pipe and the material being installed. This will affect how long the bore needs to be and at what angle you can enter and exit; refer to Planning the Bore Path.

  • Have the area of the bore path marked for utility lines (in the US call 811). Ensure that all lines are marked on your blueprints/bore plan as well.

  • Contact the local authorities to arrange for any permits and traffic control that you will need to conduct the job.

Inspecting the Proposed Job Site

Physically inspect the site as follows:

  • Note the terrain, slopes, valleys, hills, and any features not planned for previously.

    Determine the degree of slope at both the proposed entry point and exit point.

  • Determine what the soil types are in the area and, if possible, and what they are at the depth you will be boring. You may need to dig test holes at intervals along the bore path to fully determine this.

  • Walk the area of the bore path looking for any possible unmarked obstructions. Look for manholes, pedestals, old foundations, etc.

  • Identify all hazards of which you will be passing within 3 m (10 ft).

    Common hazards include the following:

    • Gas lines

    • Electrical power lines

    • Crystalline silica and other dust

      If you will be drilling through or cutting concrete, sand, or other substances that create dusts or fumes, you need to ensure that you and all workers wear breathing protection to protect your lungs from the dust.

      Danger

      Contacting underground hazards with the machine while drilling or reaming can cause explosion, electrocution, breathing problems, severe trauma, and death to you or bystanders.

      • Ensure that all personnel at the job site wear personal protective equipment including a hard hat, eye protection, electrically insulated safety boots and gloves, and hearing protection.

      • Keep bystanders and spectators away from the job site, including the complete bore path.

      • Locate and expose all electric and gas lines that you will be crossing by careful hand digging.

      • Ensure that you use the Zap-Alert system whenever operating the machine.

      Danger

      Drilling into a gas line can cause an explosion or fire, burning, injuring, or killing you or others in the vicinity of the break.

      • Do not smoke or have any source of flame near gas lines or at either end of a bore that will be crossing a gas line.

      • Keep bystanders and spectators away from the job site, including the complete bore path.

      • Locate and expose all gas lines that you will be crossing by careful hand digging.

      • Have the gas company turn off the gas to any lines you will be crossing before drilling.

      • Use the receiver to track the exact position of the drill head when approaching gas lines.

      Danger

      Drilling into an electric power line will cause the machine to become electrified and may electrocute you or any bystanders.

      • Keep bystanders and spectators away from the job site, including the complete bore path.

      • Locate and expose all electric lines that you will be crossing by careful hand digging.

      • Have the electric company turn off the power to any lines you will be crossing before drilling.

      • Use the receiver to track the exact position of the drill head when approaching electric lines.

      • Before drilling, setup and use the Zap-Alert system which is designed to notify in the case of an electric strike. If the Zap-Alert alarm triggers, stop what you are doing and do not leave the operator’s position. Refer to Deploying the Zap-Alert System for detailed instructions on using the Zap-Alert system.

      Warning

      Machining or handling stone, masonry, concrete, metal, and other materials can generate dust, mists, and fumes containing chemicals, such as silica, known to cause serious or fatal injury or illness, such as respiratory disease, silicosis, cancer, birth defects, or other reproductive harm.

      • Control dust, mist, and fumes at the source where possible. Water should be used for dust suppression when feasible.

      • Use good work practices and follow the recommendations of the manufacturer or suppliers, OSHA, and other occupational and trade associations.

      • When the hazards from inhalation cannot be eliminated, the operator and any bystanders should wear a respirator approved by OSHA for the material being handled.

      Warning

      Silicosis Warning: Grinding, cutting, or drilling stone, masonry, concrete, metal, and other materials with silica in their composition may give off dust or mist containing crystalline silica. Silica is a basic component of sand, quartz, brick, clay, granite, and numerous other minerals and rocks. Repeated and/or substantial inhalation of airborne crystalline silica can cause fatal respiratory diseases, including silicosis. In addition, some other authorities have listed respirable crystalline silica as a substance known to cause cancer. When cutting such materials, follow respiratory precautions.

Planning the Bore Path

Before setting up the job site, you need to plan the bore path, including the following:

g218955
  • Bore entry

    This is the location where you setup the machine and the drill bit enters the ground. Depending on conditions, this will typically be set back 9 to 15 m (30 to 50 ft) from the beginning of the-bore-at-depth point.

  • Beginning of bore-at-depth point

    This is the point where you want the utility line or pipe to end after installation is complete. It is typically the point at which the bore levels out and begins to bore horizontally. This may be the same as the entry point, or you may dig a separate depth-gauge hole at this point (Figure 40).

  • Bore depth

    This the depth at which you want to install the utility line or pipe.

  • Obstacles in the path

    You will need to steer around or under obstacles. It is important to know where these obstacles will be before starting so that you can plan where to begin steering prior to reaching the obstacle.

  • End of bore-at-depth point

    This is the point where you want the utility line or pipe to begin after installation is complete. Often this will also be the bore exit.

  • Bore exit

    This is the location where the drill head will exit the ground and the point at which you will pull the utility lines or pipe into the bore. If this point will be at the surface instead of at installation depth, you will need to determine the distance from the end-of-bore-at-depth location needed for steering the drill to the surface, typically 9 to 15 m (30 to 50 ft) from the end-of-the-bore-at-depth point.

Determining the Bore Entry Point

One of the more challenging aspects of planning the bore path is to determine the entry point of the bore. You need to take the following traits into account when determining the location of the entry point:

  • Bore depth

    This the depth at which you want to install the utility line or pipe. This machine is designed primarily for installations between 1 and 3 m (3.5 to 10 ft).

  • Pipe and material flexibility

    The 3 m (10 ft) pipes used on this machine can flex to an 8% pitch over the length of the pipe; this equates to a bend of no more than 20 cm (8 inches) off of a straight path (Figure 41).

    Important: If you steer the pipe to bend sharper than 20 cm (8 inches) per pipe, you may damage the pipes and their connections. You must also make steering changes gradually over the entire length of each pipe. If you steer the whole 20 cm (8 inches) in only 25 to 50 cm (1 to 2 ft) of travel, you can permanently damage the pipes.

    This flexibility is often rated in materials as a minimum bend radius, which is the radius of the circle formed if the material or pipes, connected together, were bent to form a giant circle. The minimum radius of a circle made with the pipe used with this machine is 31 m (101 ft).

  • Entry pitch

    The entry pitch is the angle at which the drill bit enters the ground. With the tracks on level ground, the stabilizers down, and the stake-down plate on the ground, the drill frame angle is about 15 degrees or a 27% pitch. This pitch will change depending on the slope of the ground and other factors of the job site. You can also reduce this pitch a bit by building up the ground under the stake-down plate before positioning the machine. You can determine the actual pitch of the drill frame by placing the drill bit and sonde housing on the frame and then use the receiver to display the pitch.

    The steeper your entry pitch is, the deeper your bore must be due to the limitations of the pipe flexibility. Typically, you need to insert the drill bit and at least 1/3 of a pipe into the ground before you can start steering toward the beginning of the bore point. Figure 42, Figure 43, and the following table illustrate the relationship between entry pitch and depth.

    g218953
    g218953

    Note: The depths given in the following table are for 3 m (10 ft) of combined drill head and pipe. As you steer up, the pitch of the steered section changes and can be monitored with the receiver. Use the following table to identify how many lengths of pipe will be necessary to insert and steer to the beginning point and help you choose an entry point.

    All measurements are approximate and will vary depending on soil conditions.

    Note: Refer to the guidance system Operator’s Manual for more information.

Given the information in the table, you can calculate the number of pipes required to reach your beginning point at the appropriate depth. Toro recommends that you start the entry point a distance back from your beginning-at-depth point by the same distance as the length of pipes you will need to reach that point. This will ensure that you have enough extra space so you will not over-steer and damage the pipes.

The following example illustrates the process given an installation using the maximum entry pitch of the machine (26%) on level ground:

g218954
  • You insert the first 3 m (10 ft) of drill bit/pipe into the ground with no steering. The end of the drill bit is 76 cm (30 inches) deep (Figure 44).

  • You begin steering up for the next 3 m (10 ft), pushing the pipes in at the maximum pitch change of 8%. This results in a change of pitch from 26% at the beginning of the 3 m (10 ft) to 18% at the end of the 3 m (10 ft) for an average pitch of 22%. Given that, the drill head lowers another 66 cm (26 inches) and is now 142 cm (56 inches) deep.

  • Continuing steering up for the next 3 m (10 ft) at an 8% pitch change, your pitch changes from 18% to 10% for an average pitch of 14%. Given that, the drill head lowers another 43 cm (17 inches) and is now 185 cm (73 inches) deep.

  • Continuing steering up for the next 3 m (10 ft) at an 8% pitch change, your pitch changes from 10% to 2% for an average pitch of 6%. Given that, the drill head lowers another 18 cm (7 inches) and is now 203 cm (80 inches) deep.

  • Leveling the drill head from 2% to 0% takes less than 1.5 m (5 ft) more for a final depth of 208 cm (82 inches). Reaching this final point took 4 and a half, 3 m (10 ft) pipes. So for this example your entry point should be 14.7 m (45 ft) back from the beginning-at-depth point of your installation.

The following example illustrates the process given an installation using the machine at an 18% pitch on level ground:

g218952
  • You insert the first 3 m (10 ft) of drill bit/pipe into the ground with no steering. The end of the drill bit is 53 cm (21 inches) deep (Figure 45).

  • You begin steering up for the next 3 m (10 ft), pushing the pipes in at the maximum pitch change of 8%. This results in a change of pitch from 18% at the beginning of the 3 m (10 ft) to 10% at the end of the 3 m (10 ft) for an average pitch of 14%. Given that, the drill head lowers another 43 cm (17 inches) and is now 96 cm (38 inches) deep.

  • Continuing steering up for the next 3 m (10 ft) at an 8% pitch change, your pitch changes from 10% to 2% for an average pitch of 6%. Given that, the drill head lowers another 18 cm (7 inches) and is now 114 cm (45 inches) deep.

  • Leveling the drill head from 2% to 0% takes less than 1.5 m (5 ft) more for a final depth of 119 cm (47 inches). Reaching this final point took 3 and a half, 3 m (10 ft) pipes. So for this example, your entry point should be 10.6 m (35 ft) back from the beginning-at-depth point of your installation.

Important: You can use the information contained in this section to determine both the space needed to steer up to the exit point if needed and also to steer around obstacles.

Mapping the Bore Path

With the information you gathered previously, map out the path of the bore, identifying the following so that you can mark the site later:

  • Entry point

  • Location of the machine and supporting equipment

  • Beginning of bore-at-depth

  • Any obstacles that you need to steer around and the locations where you need to start steering to get around or under them

  • Any utility lines you will need to cross

  • Slope and soil changes along the path that will affect the bore

  • End of the bore-at-depth

  • Exit location if it is different than the end of the bore

Marking and Preparing the Bore Path

  1. Walk the bore path, marking it on the ground with marking paint so that the receiver operator will be able to follow the path.

  2. Hand dig to expose any buried utility lines, previously marked, that the bore path will be crossing. This will allow the receiver operator to know exactly where they are.

  3. If you are exiting the bore at ground level and not in an existing trench, dig an angled hole into which the bit will enter at the end of the bore.

  4. If desired, dig a hole to the beginning-of-the-bore point where you can disconnect the pipe or lines after pulling them back.

Testing the Zap-Alert System

Danger

If the Zap-Alert system activates while drilling, the machine will become energized. If you step off of the operator platform or if someone touches the machine or wet ground near the machine or in the bore, you or they could be electrocuted, causing serious injury or death.

  • Test the Zap-Alert system before drilling.

  • Deploy the grounding stake before drilling. Ensure that the stake is fully inserted into moist soil.

  • If the Zap-Alert is triggered:

    • Stay in the seat and do not touch the ground or any other part of the machine until the power has been turned off. Do not pour liquids or urinate from the operator platform onto the ground.

    • Stop drilling, stop the drilling-fluid flow, and retract the drill out of the ground.

    • Keep everyone away from the machine.

    • Keep standing or running water and drilling fluid contained close to the machine. Keep water and drilling fluid sources away from the broken line.

    • Contact the utility company to have power shut off to the broken line. Do not reset the Zap-Alert system until the power has been turned off.

The Zap-Alert system is an electric strike sensing device on the machine that triggers a strobe light and audible alarm in the event that the drill bit, reamer, or stake breaks into an energized power line. In the event of an electric strike, the machine becomes energized, setting off the alarm.

Test the Zap-Alert system before using the drill each day, as follows:

  1. Remove the ground cable from its storage position at the rear of the machine (Figure 49).

  2. Lay the grounding stake flat on the ground away from the machine. Do not drive the stake into the ground.

    Important: Do not allow the stake to touch any part of the machine.

  3. Open the front hood; refer to Opening the Front and Rear Hoods .

  4. Connect an alligator clip from the Zap-Alert tester to the grounding stud on the Zap-Alert system (Figure 46 and Figure 47).

    g218967
    g230010
  5. Connect the other alligator clip to a metal component of the machine frame.

  6. Push the TEST button on the Zap-Alert tester (Figure 48).

Setting Up the Drill Head and Tracking System

The drill head consists of 2 parts, the drill bit and the sonde housing (Figure 54).

g023076

Drill bits vary in size and type to meet the various soil conditions you may need to drill through. Some of the possibilities are as follows:

  • Straight blade—Used in a wide range of medium density soils.

  • Bent blade—Used in medium to soft soils. This bit has an added 20° bend to increase steering performance in soft soils.

  • Triangle point blade—Use in hard and rocky soils. This bit has carbide edges to reduce wear.

All of the above bits come in varying widths. A wider blade increases your ability to steer in soft soils. A narrower blade moves through hard soils better. Contact your Authorized Service Dealer for a complete list of available blades.

The sondes and receivers are essential to track the position of the drill head throughout the drilling operation. The sonde housing on the drill head opens up to accept the sonde beacon which works with the receiver to track the location, pitch, direction, head orientation, and more of the drill head. Refer to the Tracking System Operator’s Manual for instructions on using the system.

To install the sonde beacon into the sonde housing on the drill head, complete the following:

  1. Replace the batteries in the sonde beacon as described in the Tracking System Operator’s Manual.

  2. Loosen the screws securing the housing cover to the housing and remove the cover (Figure 55).

    g023073
  3. Insert the sonde beacon with the forward end toward the drill bit into the sonde housing (Figure 56).

    g218969
  4. Install the housing cover and secure it with the screws (Figure 55).

Setting up the Machine for Drilling

  1. Using the travel pendant, tram the machine to the location that you have prepared for it, ensuring that the front of the machine is the proper distance back from entry point and the drill frame is in line with the bore path.

  2. Drive up to the location and make sure that all utilities are located and marked prior to drilling.

  3. Remove the console covers.

    Note: Store them someplace safe for the day.

  4. Lower the pipe loading guard (Figure 57).

    g230516
  5. Push down on the operator platform latch and swing the platform out to the desired position, ensuring that it locks in place (Figure 58).

    Note: The operator platform has 5 positions: travel (swung all the way into the machine), full-out, and 3 intermediate positions.

    g218956

Deploying the Zap-Alert System

The Zap-Alert system is an electric strike sensing device on the machine that triggers a strobe light and audible alarm in the event that the drill bit, reamer, or stake breaks into an energized power line. In the event of an electric strike, the machine becomes energized, setting off the alarm.

Danger

If the Zap-Alert system activates while drilling, the machine, including the operator’s platform, will become energized. If you step off the operator platform or if someone touches the machine or wet ground near the machine or in the bore, you or they could be electrocuted causing serious injury or death.

  • Test the Zap-Alert system before drilling.

  • Deploy the grounding stake before drilling. Ensure that the stake is fully inserted into moist soil.

  • If the Zap-Alert is triggered:

    • Stay in the seat and do not touch the ground or any other part of the machine until the power has been turned off. Do not pour liquids or urinate from the operator platform onto the ground.

    • Stop drilling, stop the drilling-fluid flow, and retract the drill out of the ground.

    • Keep everyone away from the machine, wet ground near the machine or running from the machine, and any open sources of water/mud that is in the bore and contacting the broken line.

    • Contact the utility company to have power shut off to the broken line. Do not reset the Zap-Alert system until the power has been turned off.

  1. Remove the grounding stake from the holder on the side of the operator platform (Figure 59).

    g218966
  2. Move the stake directly away from the machine, perpendicular to the drill frame and drive it into the ground until the handle touches the ground.

  3. If the ground is dry where you put the stake, soak it with water before using the machine to ensure good electrical contact.

Lowering the Stakes

Preparing the Machine to Lower the Stakes

  1. Move the operator station to the desired angle, switch the DRILL/SETUP switch to the DRILL position, and raise the pipe elevators, so that the pipe is resting on the elevators; refer to Starting the First Pipe.

  2. Remove the pipe box transport pins.

  3. Power on the exit-side lockout system.

  4. Load the first pipe and install the sonde and the drill head; refer to Starting the First Pipe.

  5. Place the drill head on the drill frame, and take a pitch reading using the receiver; refer to the Tracking System Operator’s Manual.

Lowering the Stakes

  1. Move the operator station to the desired angle, switch the DRILL/SETUP switch to the DRILL position, and raise the pipe elevators, so that the pipe is resting on the elevators; refer to Starting the First Pipe.

  2. Switch the DRILL/SETUP switch to the SETUP position, lower the thrust frame, tilting the drill frame until the plate contacts the ground (Figure 60).

    g218964
  3. Lower the rear stabilizers until they contact the ground firmly, or until the desired entry angle is achieved (Figure 61).

    Note: The rear of the tracks should just start to lift off the ground.

    Note: If the ground is soft, place timber below the stabilizers and lower the stabilizers.

    g218941
  4. Deploy the zap-alert system; refer to Deploying the Zap-Alert System

  5. Push the lower stake direction on the right joystick and spin the right stake auger until it seats fully.

  6. Repeat this procedure for the left-side stake.

Connecting to a Drilling-Fluid Source

When drilling and reaming, you pump a mixture of bentonite clay, water, and sometimes other ingredients, collectively called drilling fluid or “mud,” through the pipe and into the bore. This drilling fluid, or “mud,” does the following for your bore:

  • Lubricates the drill head

  • Keeps the sonde cool

  • Loosens the soil into which the drill is cutting

  • Penetrates and binds loose soil to keep them from collapsing on the bore pipe.

The specific mixture you need will vary depending on your soil type and the operation you are performing; refer to your mixing system Operator’s Manual for details.

Conversely, for some jobs (depending on the soil type and distance), you can pump screened water from a natural water source, such as a lake or river, through the drill instead of mixed drilling fluid.

Setting Up the Mixing System

Set up your mixing system near the directional drill location, preferably down wind so that fumes from the mixing system engine do not bother you while drilling. Follow the instructions provided in the mixing system Operator’s Manual for setting it up and using it.

Complete the following to connect the exit hose from the mixing system to the drilling-fluid pump on the machine:

  1. Raise the cam-lock levers on the pump-inlet cap and remove the cap (Figure 62).

    g218943
  2. Insert the hose from the mixing system over the pump inlet and secure it with the cam-lock levers.

Setting Up the Pump to Use a Natural Water Source

To set up a pump to use a natural water source, ensure that you use the Y-screen to filter all materials other than water.

  1. Remove the pump-inlet cap (Box A of Figure 63).

    g220801
  2. Align the Y-screen with the threads on the pump (Box B of Figure 63).

  3. Rotate and tighten the Y-screen onto the pump.

  4. Attach the hose to the Y-screen, and begin pumping from the natural water source.

During Operation

During Operation Safety

General Safety

  • The owner/operator can prevent and is responsible for accidents that may cause personal injury or property damage.

  • Wear appropriate clothing, including long pants; eye and hearing protection; slip-resistant, substantial foot protection; and hard hats. Tie back long hair and do not wear jewelry.

  • Do not operate the machine while ill, tired, or under the influence of alcohol or drugs.

  • Never carry passengers on the machine and keep bystanders and pets away from the machine during operation.

  • Operate the machine only in good visibility to avoid holes or hidden hazards.

  • Keep your hands and feet away from moving parts.

  • Look behind and down before backing up to be sure of a clear path.

  • Use care when approaching blind corners, shrubs, trees, or other objects that may obscure your vision.

  • Do not operate near drop-offs, ditches, or embankments.

  • Stop the machine whenever you are not operating it.

  • Stop the machine and inspect the after striking an object or if there is an abnormal vibration in the machine. Make all necessary repairs before resuming operation.

  • Slow down and use caution when making turns and crossing roads and sidewalks with the machine. Always yield the right-of-way.

  • Never run an engine in an area where exhaust gasses are enclosed.

  • Never leave a running machine unattended.

  • Before leaving the operating position, do the following:

    • Move the machine to level ground.

    • Shut off the engine and remove the key.

    • Wait for all moving parts to stop.

  • Do not operate the machine when there is the risk of lightning.

  • Do not use the machine as a towing vehicle.

  • Use accessories, attachments, and replacement parts approved by The Toro® Company only.

Slope Safety

When operating the machine on a slope, the operator must account for many variables, such as the amount, distribution, and height of the load; the stability of the ground; uneven terrain and obstacles; and the condition of the brakes. These and other variables make it impractical to designate the maximum angle at which the operator can safely use the machine for all slopes and situations.

Slopes are a major factor related to loss of control and rollover accidents, which can result in severe injury or death. The operator is responsible for safe slope operation. Operating the machine on any slope requires extra caution. Before using the machine on a slope, the operator must do the following:

  • Review and understand the slope instructions in the manual and on the machine.

  • Evaluate the site conditions of the day to determine if the slope is safe for machine operation. Use common sense and good judgment when performing this evaluation. Changes in the terrain, such as moisture, can quickly affect the operation of the machine on a slope.

  • Walk beside the machine when tramming up and down slopes.

  • Identify hazards at the base of the slope. Do not operate the machine near drop offs, ditches, embankments, water or other hazards. The machine could suddenly roll over if a track goes over the edge or the edge collapses. Keep a safe distance (twice the width of the machine) between the machine and any hazard.

  • Avoid starting, stopping or turning the machine on slopes. Avoid making sudden changes in speed or direction; turn slowly and gradually.

  • Do not operate a machine under any conditions where traction, steering or stability is in question. Be aware that operating the machine on wet terrain, across slopes or downhill may cause the machine to slide even if the tracks are stopped.

  • Remove or mark obstacles such as ditches, holes, ruts, bumps, rocks, or other hidden hazards. Uneven terrain could overturn the machine.

Diesel Particulate Filter Regeneration

The diesel particulate filter (DPF) is part of the exhaust system. The diesel-oxidation catalyst of the DPF reduces harmful gasses and the soot filter removes soot from the engine exhaust.

The DPF regeneration process uses heat from the engine exhaust to incinerate the soot accumulated on the soot filter, converting the soot to ash, and clears the channels of the soot filter so that filtered engine exhaust flows out the DPF.

The engine computer monitors the accumulation of soot by measuring the back pressure in the DPF. If the back pressure is too high, soot is not incinerating in the soot filter through normal engine operation. To keep the DPF clear of soot, remember the following:

  • Passive regeneration occurs continuously while the engine is running—run the engine at full engine speed when possible to promote DPF regeneration.

  • If the back pressure is too high, the engine computer signals you through the display when additional processes (assist and reset regeneration) are running.

Operate and maintain your machine with the function of the DPF in mind. Engine load, at high idle engine speed, generally produces adequate exhaust temperature for DPF regeneration.

Important: Minimize the amount of time that you idle the engine or operate the engine at low-engine speed to help reduce the accumulation of soot in the soot filter.

Caution

The exhaust temperature is hot (approximately 600°C (1,112°F) during DPF parked regeneration or recovery regeneration. Hot exhaust gas can harm you or other people.

  • Never operate the engine in an enclosed area.

  • Make sure that there are no flammable materials around the exhaust system.

  • Never touch a hot exhaust system component.

  • Never stand near or around the exhaust pipe of the machine.

DPF Soot Accumulation

  • Over time, the DPF accumulates soot in the soot filter. The computer for the engine monitors the soot level in the DPF.

  • When enough soot accumulates, the computer informs you that it is time to regenerate the diesel particulate filter.

  • DPF regeneration is a process that heats the DPF to convert the soot to ash.

  • In addition to the warning messages, the computer reduces the power produced by the engine at different soot-accumulation levels.

Refer to the Software Guide for fault messages and recommended actions.

DPF Ash Accumulation

  • The lighter ash is discharged through the exhaust system; the heavier ash collects in the soot filter.

  • Ash is a residue of the regeneration process. Over time, the diesel particulate filter accumulates ash that does not discharge with the engine exhaust.

  • The computer for the engine calculates the amount of ash accumulated in the DPF.

  • When enough ash accumulates, the engine computer sends information to the display in the form of a system advisory or an engine fault to indicate the accumulation of ash in the DPF.

  • The advisory and faults are indications that it is time to service the DPF.

  • In addition to the warnings, the computer reduces the power produced by the engine at different ash-accumulation levels.

Refer to the Software Guide for fault messages and recommended actions.

Types of Diesel Particulate Filter Regeneration

Types of diesel particulate filter regeneration that are performed while the machine is operating:

Type of RegenerationConditions for DPF regenerationDPF description of operation
PassiveOccurs during normal operation of the machine at high-engine speed or high-engine loadThe display does not display an icon indicating passive regeneration.
During passive regeneration, the DPF processes high-heat exhaust gasses; oxidizing harmful emissions and burning soot to ash.
Refer to Passive DPF Regeneration.
AssistOccurs as a result of low-engine speed, low-engine load, or after the computer detects back pressure in the DPFDuring assist regeneration, the computer controls the intake throttle to increase the exhaust temperature, enabling assist regeneration to occur.
Refer to Assist DPF Regeneration.
ResetOccurs after assist regeneration only if the computer detects that assist regeneration did not sufficiently reduce the soot levelDuring reset regeneration, the computer controls the intake throttle and fuel injectors to increase the exhaust temperature during regeneration.
Also occurs after the first 50 engine hours and then every 100 hours to reset baseline sensor readingsRefer to Reset Regeneration.

Types of diesel particulate filter regeneration that require you to park the machine:

Type of RegenerationConditions for DPF regenerationDPF description of operation
ParkedSoot buildup occurs as a result of prolonged operation at low-engine speed or low-engine load. May also occur as a result of using incorrect fuel or oilWhen the parked-regeneration icon Graphic is displayed on the display, a regeneration is requested.
The computer detects back pressure due to soot buildup and requests a parked regeneration
 • Perform the parked regeneration as soon as possible to avoid needing a recovery regeneration.
• A parked regeneration requires 30 minutes to complete.
• You must have at least a 1/4 tank of fuel in the tank.
• You must park the machine to perform a recovery regeneration.
Refer to Parked Regeneration and Recovery Regeneration and the Software Guide for your machine.
RecoveryOccurs as a result of ignoring parked regeneration requests and continuing operation, adding more soot when the DPF is already in need of a parked regenerationWhen the recovery-regeneration icon Graphic is displayed on the display, a recovery regeneration is requested.
• A recovery regeneration requires approximately 4 hours to complete.
• You must have at least a 1/2 tank of fuel in the machine.
• You must park the machine to perform a recovery regeneration.
Refer to Parked Regeneration and Recovery Regeneration and the Software Guide for your machine.

Passive DPF Regeneration

  • Passive regeneration occurs as part of normal engine operation.

  • While operating the machine, run the engine at full-engine speed when possible to promote DPF regeneration.

Assist DPF Regeneration

  • The computer takes control of the intake throttle to increase the temperature of the engine exhaust.

  • While operating the machine, run the engine at full engine speed when possible to promote DPF regeneration.

Reset Regeneration

  • The computer takes control of the intake throttle and changes the fuel injection operation to increase the temperature of the engine exhaust.

    Important: The assist/reset-regeneration icon indicates that the exhaust temperature discharged from of your machine may be hotter than during regular operation.

  • While operating the machine, run the engine at full engine speed when possible to promote DPF regeneration.

Parked Regeneration and Recovery Regeneration

Refer to the Software Guide for more information.

Preparing to Perform a Parked or Recovery Regeneration

Ensure that the machine has fuel in the tank for the type of regeneration you are performing:

  • Parked Regeneration: Ensure that you have 1/4 tank of fuel before performing the parked regeneration.

  • Recovery Regeneration: Ensure that you have 1/2 tank of fuel before performing the recovery regeneration.

Move the machine outside to an area away from combustible materials.

Refer to the Software Guide for the procedure to perform the parked or recovery regeneration.

Drilling the Bore

Starting the First Pipe

The Software Guide is used in this procedure.

  1. Ensure that all bystanders are away from the machine and that the exit-side lockout is ON.

  2. Move the drill carriage fully down the drill frame and spray the spindle threads with thread joint compound, then return the drill carriage to the upper end of the frame (Figure 59).

    g023075
  3. Change the row selector to row 1 on the display to rotate the cam assembly to the first row in the pipe holder; refer to the Software Guide.

  4. Lower the pipe elevators to load a pipe into the cam assembly.

  5. Rotate the cam assembly with the pipe toward the drill frame, and extend the pipe grippers until the pipe is centered over the drill string and in front of the drill spindle on the carriage.

  6. Raise the pipe elevators.

  7. Engage the exit side lockout system and rotate the drill spindle clockwise and move the carriage slowly forward to insert the spindle into the female end of the pipe (Figure 65).

    g218963
  8. Continue to move the drill carriage slowly down the frame until the male threads on the pipe are under the thread-joint-compound applicator and apply thread-joint compound to the threads.

  9. Continue to rotate the drive spindle clockwise, until the male pipe threads are fully seated into the sonde housing or the lead bar.

  10. Release and retract the pipe gripper, rotating it all the way out to the park position.

    Important: Ensure that you fully retract the pipe gripper and rotate it all the way out or the carriage may collide with the gripper, damaging the machine.

    Note: Torque the threads to 2305 N∙m (1,700 ft-lb).

Installing the Drill Head

Warning

If the drill rotates or extends while you or others are manually working on the drill bit or pipe in front of the machine, the worker could get caught in the bit or pipe causing serious injury, amputation, or death.

  • Enable the exit-side lockout on the exit-side-lockout transmitter before approaching the dill bit or pipe when attached to the machine. This disables the drill carriage motion and rotary functions.

  • Do not wear loose clothing or jewelry when working on a drill bit or pipe attached to the machine. Tie long hair up and out of the way.

  1. Using the exit-side-lockout transmitter, enable the exit side lockout.

  2. Hand thread the lead bar onto the pipe threads then clear away from the front of the machine.

  3. When the area is clear of people, push the exit-side-lockout reset switch on the front control panel.

  4. Pull the drill pipe and lead bar back through the pipe guide and into the wrenches, aligning the shoulder of the upper joint of the lead bar with the upper wrench (Figure 66).

    Important: Do not clamp the wrench on the body of a pipe or it may damage the pipe. Grip the pipes on the shoulder of the pipe joint.

    g218962
  5. Using the upper wrench, clamp the lead bar and tighten it to full machine torque.

  6. Using the exit-side-lockout transmitter, enable the exit-side lockout.

  7. Double check the drill head and bit to ensure that the fluid ports are clean and free from obstructions.

  8. Install the drill head onto the end of the lead bar as directed by the drill head manufacturer, then clear away from the front of the machine.

    Important: Do not pull the drill head into the pipe guide, or you may damage the machine or the drill head.

Boring the Entry Shaft

The first step is to create the entry shaft. Push and bore the drill bit and the first few pipes into the ground at an angle from 0 to 16 degrees (with the tracks flat on the ground) until you reach the desired depth.

Important: Drill and ream in a clockwise rotation. If you use a counterclockwise rotation, the pipe will disconnect from each other and may be disconnected underground.

  1. When the area is clear of people, disable the exit-side lockout using the exit-side-lockout transmitter; push the exit-side-lockout, reset switch on the control panel.

  2. Turn on the drilling fluid pump switch and allow the fluid pressure to build to 1379 to 2068kPa (200 to 300 psi).

  3. Rotate the drill head until the bit is at the 6 o’clock position.

  4. Move the carriage forward driving the bit straight into the ground until the entire dill housing is underground.

  5. Continue pushing forward and begin rotating the drill spindle clockwise to initiate the drilling action.

  6. Drill forward until the carriage reaches the end of the frame, then retract it about 6 mm (1/4 inch).

Adding Drill Pipes

  1. Align the pipe joint in the wrench assembly.

  2. Close the lower wrench (stationary wrench) onto the first pipe.

    Note: The drilling fluid automatically shuts off when you activate the lower wrench.

  3. Pull back the carriage approximately 12.7 mm (0.5 inch).

    Note: This allows the carriage to float and not damage the pipe threads.

  4. Rotate the drill head counterclockwise until the spindle is completely removed from the pipe.

  5. Spray the spindle with thread joint compound, then return the drill carriage to the upper end of the frame.

  6. Rotate the cam assembly to the closest row of pipes in the pipe holder.

  7. Lower a pipe into the cam assembly and grip it in place.

  8. Rotate the cam assembly toward the drill frame, and extend the pipe grippers until the pipe is centered over the drill string and in front of the spindle on the carriage.

  9. Rotate the drill spindle clockwise and move the carriage slowly forward to insert the spindle into the female end of the pipe (Figure 65).

    Note: Tighten the joint until the pipe is rotating with the spindle.

  10. Move the drill carriage slowly down the frame until the male threads on the pipe are under the thread-joint-compound applicator and apply thread-joint compound to the threads.

  11. Rotate the drill spindle clockwise and move the carriage slowly forward to insert the male end of the pipe into the female end of the previous pipe. Tighten the joint until you reach no more than 2,304 N∙m (1,700 ft-lb).

  12. Release and retract the pipe gripper, rotating it all the way out past the third row of pipes.

    Important: Ensure that you fully retract the pipe gripper and rotate it all the way out; otherwise the carriage may collide with the gripper, damaging the machine.

  13. Release the wrench and continue the drilling operation.

Steering the Drill Head

The drill bit is shaped like a wedge, angled from one side of the bit to the other. When you push the bit through the soil without rotating it, it moves toward the direction that the wedge is pointing. When you rotate the pipe and drill head, it bores through the soil in a straight path.

g023111

When drilling, a crew member follows the drill head as it progresses. The receiver receives signals from the sonde in the drill head identifying its position, depth, pitch, direction, transmitter temperature, and orientation in the soil. The remote console is a screen that remains near you (the drill operator) to show you the information from the receiver while drilling so that you can make steering decisions.

For detailed information on using the receiver and remote console to guide the drill head, refer to the Operator’s Manual that came with your receiver.

Important: Do not steer the drill head more than 20 cm (8 inches) off center for every 3 meters (10 ft) of forward travel. If you steer more than this, you will damage the drill pipes.

Boring the Horizontal Shaft

After creating the entry shaft, you gradually steer the drill head up while pushing forward, following the planned bore path. When you reach the desired depth, level out the drill head and bore the horizontal shaft, adding pipes as you go. While boring, pay close attention to the information relayed back to you by the crew member about the status and location of the drill head to ensure that you are following the planned path.

Important: While drilling, watch the sonde temperature. All sondes have a maximum temperature above which they will be damaged. Friction between the drill head and the soil causes the temperature to raise. To reduce the temperature, slow down, decrease forward pressure, and increase the drilling fluid flow. If the drill head is entering a soil type other than what it is designed for, that can also raise the temperature. Assess the situation and pull out the drill head and change it if necessary.

If you run into an obstruction, do the following:

  1. Increase the flow of the drilling fluid for a few seconds without drilling, then attempt to continue drilling forward.

    This may loosen the obstruction and allow you to push past it.

  2. If the obstruction persists, try 1 or more of the following options:

    • If the obstruction is in an area where you can dig, stop the drill head with the Exit Side Lockout and dig down to the obstruction to identify it and remove it if possible.

    • Pull the drill head back 15 m (50 ft) or more and steer the drill head to the side, marking a new drill path around the obstacle.

      Important: Do not steer the drill head more than 20 cm (8 inches) off center for every 3 meters (10 ft) of forward travel. If you steer more than this, you will damage the drill pipes.

    • If the obstruction is actually a change in soil types, such as a zone of rocky soil, pull the drill head all the way back and change to a drill bit appropriate for drilling through the new soil type.

Exiting the Ground

As you approach the end of the bore, steer the drill head to the exit point, keeping the steering limits in mind as you do so. Before exiting the ground, ensure that everyone is away from the exit point. As soon as you break through, stop the drilling-fluid flow. Extend the drill forward until the entire drill head is out of the ground.

Backreaming and Pullback

After drilling the initial bore, you attach a reamer to the pipe, which is then connected to a the product you are installing. The reamer is designed to widen the bore, pack the walls, and lubricate the passage of the product into the bore.

The following reamers are available from your Authorized Service Dealer in various sizes to meet your needs and soil conditions:

  • Carbide step-wing cutter—Use this reamer in sandy and medium clay soil conditions to mix the drilling fluid with the soil, making a mixture that flows easily around the product being pulled.

  • Cast cone packer—Use this reamer in soils that pack easily, such as soft clay, peat, and loam, to pack the sides of the bore, maintaining the bore opening.

  • Fluted reamer—Use this reamer in hard clay and rocky soils; it combines the features of the other 2 reamers.

Connecting the Reamer and Product

Warning

If the drill rotates or extends while you or others are manually working on the drill bit or pipe in front of the machine, the worker could get caught in the bit or pipe causing serious injury, amputation, or death.

  • Enable the exit-side lockout on the exit-side-lockout transmitter before approaching the dill bit or pipe when attached to the machine. This disables the drill carriage and rotary gearbox.

  • Do not wear loose clothing or jewelry when working on a drill bit or pipe attached to the machine. Tie long hair up and out of the way.

  1. Using the exit-side-lockout transmitter, enable the exit side lockout.

    Important: Do not use pipe wrenches.

  3. Double check the reamer to ensure that the fluid ports are clean and free from obstructions.

  4. Install the reamer and swivel onto the end of the lead bar as directed by the reamer manufacturer.

  5. Connect the product to the reamer using an appropriate pulling connection; refer to your Authorized Service Dealer to acquire the appropriate puller to meet your requirements.

Removing Drill Pipes

  1. Using the exit-side-lockout transmitter, enable the exit side lockout.

  2. Install a drill-pipe wiper around the pipe and into the retaining bracket on the front of the machine.

    This removes most of the dirt and mud from the pipe as you pull it back into the machine, keeping the machine clean. Contact your Authorized Service Dealer to purchase drill-pipe wipers.

    g234769
    g234768
  3. Disengage the exit-side lockout and reset the system.

  4. Begin rotating the drill spindle clockwise and slowly retract the drill carriage to pull the pipe back into the machine.

  5. When the joint between the pipes is centered between the 2 wrenches, the drill carriage stops, and a green light illuminates behind the spray valve.

  6. Close the lower wrench onto the pipe joint.

    Note: The drilling fluid automatically shuts off when you close the lower wrench.

  7. Close the upper wrench onto the pipe joint.

  8. Rotate the upper wrench counterclockwise until the joint is loosened.

  9. Release the upper wrench and retract the pipe gripper arms.

  10. Rotate the drill spindle counterclockwise moving rearward slowly until the pipes are separated.

  11. Move the drill carriage back until the male-pipe threads just clear the female end of the lower pipe, then close the upper wrench onto the pipe shoulder, but not on the threads.

  12. Rotate the drill spindle counterclockwise until the upper-pipe joint is loose but not separated.

  13. Release the upper wrench.

  14. Rotate the cam assembly to the drill frame, extend the pipe-gripper arms to the pipe, and grip the pipe to support it.

  15. Move the drill carriage back until the pipe is lined up with the pipe holder load position, illuminating the green light.

  16. Rotate the drill spindle counterclockwise moving rearward slowly until the spindle fully separates from the pipe.

  17. Send the carriage to the rear stop on the thrust frame.

  18. Retract the pipe gripper arms.

  19. Rotate the pipe cam to the desired row.

    Note: Fill the outside rows first.

  20. Release the pipe gripper and raise the pipe into the pipe box using the pipe elevators.

  21. Rotate the pipe gripper past the third row of pipes.

    Important: Ensure that you fully retract the pipe gripper and rotate it all the way out; otherwise, the carriage may collide with the gripper, damaging the machine.

  22. Move the drill spindle down the thrust frame and spray the spindle with thread joint compound once it is positioned under the applicator.

  23. Rotate the drill spindle clockwise and move the carriage slowly forward to insert the spindle into the female end of the pipe secured in the lower wrench.

    Note: Tighten the joint until you reach no more than 2,304 N∙m (1,700 ft-lb).

  24. Release the lower wrench and continue reaming/retraction as needed.

Removing the Last Pipe and the Reamer

Important: Do not pull the drill head into the pipe guide or you may damage the machine or the drill head.
