Fuel Safety

Danger

Gasoline is extremely flammable and vapors are explosive.

A fire or explosion from gasoline can burn you, others, and cause property damage.

  • Fill the fuel tank outdoors on level ground, in an open area, when the engine is cold. If fuel is spilled, Do Not attempt to start the engine. Move away from the area of the spill and avoid creating any source of ignition until fuel vapors have dissipated.

  • Do Not refill the fuel tank or drain the machine indoors or inside an enclosed trailer.

  • Never smoke when handling gasoline, and stay away from an open flame or where gasoline fumes may be ignited by spark.

  • Add fuel before starting the engine. Never remove the cap of the fuel tank or add fuel when engine is running or when the engine is hot.

  • Store gasoline in an approved container and keep it out of the reach of children.

  • Do Not operate without entire exhaust system in place and in proper working condition.

  • In certain conditions during fueling, static electricity can be released causing a spark which can ignite gasoline vapors.

    • Do Not fill containers inside a vehicle or on a truck or trailer bed with a plastic liner. Always place containers on the ground and away from your vehicle before filling.

    • When practical, remove gas-powered equipment from the truck or trailer and refuel the equipment with its wheels on the ground. If this is not possible, then refuel such equipment on a truck or trailer from a portable container, rather than from a gasoline dispenser nozzle.

    • If a gasoline dispenser nozzle is used, keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete. Do Not use a nozzle lock open device.

  • Do Not overfill the fuel tank. Fill the fuel tank to the bottom of the filler neck. The empty space in the tank allows gasoline to expand. Overfilling may result in fuel leakage or damage to the engine or emission system.

  • Gasoline is harmful or fatal if swallowed. Long-term exposure to vapors may cause serious injury and illness.

    • Avoid prolonged breathing of vapors.

    • Keep face away from nozzle and gas tank/container opening.

    • Keep away from eyes and skin.

  • To help prevent fires:

    • Keep engine and engine area free from accumulation of grass, leaves, excessive grease or oil, and other debris which can accumulate in these areas.

    • Clean up oil and fuel spills and remove fuel soaked debris.

    • Allow the machine to cool before storing the machine in any enclosure. Do Not store the machine or fuel container, or refuel, where there is an open flame, spark, or pilot light such as on a water heater or other appliance.

Operating Instructions

During Operation Safety

General Safety

The operator must use their full attention when operating the machine. Do Not engage in any activity that causes distractions; otherwise, injury or property damage may occur.

Warning

Operating engine parts, especially the muffler, become extremely hot. Severe burns can occur on contact and debris, such as leaves, grass, brush, etc. can catch fire.

  • Allow engine parts, especially the muffler, to cool before touching.

  • Remove accumulated debris from muffler and engine area.

Caution

Chemicals are hazardous and can cause personal injury.

  • Read the directions on the chemical labels before handling the chemicals and follow all manufacturer recommendations and precautions.

  • Keep chemicals away from your skin. Should contact occur, wash the affected area thoroughly with soap and clean water.

  • Wear goggles, gloves, and any other protective equipment recommended by the chemical manufacturer.

  • Operate the engine only in well-ventilated areas. Exhaust gases contain carbon monoxide, which is an odorless deadly poison.

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

  • Operate the machine only in good visibility and appropriate weather conditions. Do Not operate the machine when there is the risk of lightning.

  • Keep away from holes, ruts, bumps, rocks, and other hidden hazards. Use care when approaching blind corners, shrubs, trees, tall grass or other objects that may hide obstacles or obscure vision. Uneven terrain could overturn the machine or cause the operator to lose their balance or footing.

  • Start the engine with your feet well away from the tines and spreader discharge areas.

  • Do Not operate the machine without all safety shields, guards, switches, and other devices in place and in proper working condition.

  • Keep clear of the discharge area at all times.

  • Keep your hands and feet away from the moving parts. Keep clear of the tines and discharge area at all times.

  • Be aware of the discharge/spreading path and direct discharge away from others. Avoid discharging material against a wall or obstruction as the material may ricochet back toward the operator. Raise the tines, slow down, and use caution when crossing surfaces other than grass and when transporting the machine to and from the work area.

  • Be alert, slow down and use caution when making turns. Look behind and to the side before changing directions. Do Not operate in reverse unless absolutely necessary.

  • Stop spreading when making tight turns to minimize uneven distribution pattern, application rate, and chemical drift.

  • Chemicals may drift and cause injury to people and animals; it may also damage plants, soil, or other property.

  • Park the machine on level ground. Stop engine, wait for all moving parts to stop, and remove key.

    • Before checking, cleaning or working on the machine.

    • After striking a foreign object or abnormal vibration occurs (inspect the machine for damage and make repairs before restarting and operating the machine).

    • Before clearing blockages.

    • Whenever you leave the machine. Do Not leave a running machine unattended.

  • Stop engine, wait for all moving parts to stop, and engage parking brake:

    – Before refueling

  • Tragic accidents can occur if the operator is not alert to the presence of children. Children are often attracted to the machine and the working activity. Never assume that children will remain where you last saw them.

    • Keep children out of the working area and under the watchful care of another responsible adult, not the operator.

    • Be alert and turn the machine off if children enter the area.

    • Before and while backing or changing direction, look behind, down, and side-to-side for small children.

    • Never allow children to operate the machine.

    • Do Not carry children, even if the aerator or spreader is not in use. Children could fall off and be seriously injured or interfere with the safe operation of the machine. Children that have been given rides in the past could suddenly appear in the working area for another ride and be run over or backed over by the machine.

  • Reduce the weight of the load when operating on hills and rough terrain to avoid tipping or overturning of the machine.

  • Granular materials can shift. This shifting happens most often while turning, going up or down hills, suddenly changing speeds, or while driving over rough surfaces. Shifting loads can cause the machine to tip over.

  • When operating with a heavy load, reduce your speed and allow for sufficient stopping distance. Use extra caution on slopes.

  • Reduce speed and load when operating on rough terrain, uneven ground, and near curbs, holes, and other sudden changes in terrain. Loads may shift, causing the machine to become unstable.

    Warning

    Sudden changes in terrain may cause abrupt steering wheel movement, possibly resulting in hand and arm injuries.

    Reduce speed when operating on rough terrain or near curbs.

Slope Safety

  • 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:

    • 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.

  • Operate across slopes, never up and down. Avoid operation on excessively steep or wet 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 wheel goes over the edge or the edge collapses. Keep a safe distance (twice the width of the machine) between the machine and any hazard. Use a walk behind machine or a hand held tool to operate in these areas.

  • 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 grass, across slopes or downhill may cause the machine to lose traction. Loss of traction to the drive wheels may result in sliding and a loss of braking and steering. The machine can slide even if the drive wheels are stopped.

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

  • Use extra care while operating with accessories or attachments. These can change the stability of the machine and cause a loss of control. Follow directions for counter weights.

  • If you lose control of the machine, step off and away from the direction of travel of the machine.

Starting the Engine

  1. Leave the motion control levers in neutral and engage the parking brake.

  2. Set the throttle to the “FAST” position.

  3. On a cold engine, pull the choke knob upward into the “ON” position. On a warm engine, leave the choke in the “OFF” position.

  4. Turn ignition switch to the “START” position. Release the switch as soon as the engine starts.

    Important: Do Not crank the engine continuously for more than ten seconds at a time. If the engine does not start, allow a 60 second cool-down period between starting attempts. Failure to follow these guidelines can burn out the starter motorEngine may be difficult to start in temperatures under 30°F (-1 °C).

  5. If the choke is in the “ON” position, gradually return choke to the “OFF” position as the engine warms up.

Lowering the Tines

Danger

The rotating tines are dangerous. Tine contact can cause serious injury or death.

Do Not put hands or feet under the machine when the engine is running.

  1. Disengage the parking brake. Set throttle to “FAST” position.

  2. Press the thumb switch until desired tine depth is achieved.

    Important: The tines are rotating when the tines are lowered and the motion control lever is moved out of the neutral position.

  3. Once desired tine depth is achieved, move the motion control levers forward to aerate.

Important: Keep the drive tires on the ground at all times to maximize lateral machine stability and aeration quality.

Raising the Tines

To raise the tines, press the right thumb switch until the tines reach desired height, then release.

Stopping the Engine

  1. Move the motion control levers back to the neutral position and bring the machine to a full stop.

  2. Press the right thumb switch until the tines reach desired height, then release.

  3. Place the throttle midway between the “SLOW” and “FAST” positions.

  4. Allow the engine to run for a minimum of 15 seconds, then turn the ignition switch to the “OFF” position to stop the engine.

  5. Engage the parking brake.

  6. Remove the key to prevent children or other unauthorized persons from starting the engine.

Driving the Machine

Caution

Machine can spin very rapidly by positioning one lever too much ahead of the other. Operator may lose control of the machine, which may cause damage to the machine or injury.

  • Use caution when making turns.

  • Slow the machine down before making sharp turns.

Important: To begin movement (forward or backward), the brake lever must be disengaged (pushed forward) before the motion control levers can be moved.

    To turn left or right, pull the motion control lever back toward neutral in the desired turn direction. The tines can be in the down position when making gradual turns.

    To make zero turns, raise the tines using the right thumb switch.

    Important: Do Not make a zero turn when the tines are down as turf tearing will result.

    The machine will move faster the farther the motion control levers are moved from the neutral position.

  4. To stop, position both motion control levers in the neutral operate position.

    Note: Stopping distance may vary depending on the spreader load.

Driving in Reverse

  1. Move the motion control levers to the neutral operate position.

  2. To move rearward in a straight line, slowly move both levers rearward with equal pressure.

    Important: Do Not drive in reverse when the tines are down as turf tearing will occur.

  3. Move the bar forward to obtain the fastest speed.

    Move the bar backward to obtain the slowest speed.

  4. On both sides, tighten the knobs.

Important: Make sure the knobs are tight so the front reference/speed control bar does not move during operation.

Operating the Spreader

The spreader disperses free-flowing granular substances such as grass seed, fertilizer, ice melt, etc. When using the spreader, first fill the granule hopper, then apply to the work area, and finally clean the hopper. It is important to complete all three of these steps to avoid damaging the spreader.

Note: Clean your spreader thoroughly after all applications.

Before Operating the Spreader

Make sure the spreader has been calibrated for the material to be spread before starting (see Calibrating the Spreader section).

Important: Verify that the proper application rate has been set prior to filling the hopper.

Filling the Spreader Hopper

  1. Stop the machine on a level surface, move motion control lever to the neutral position, stop the engine, and set the parking brake.

  2. Use the Spreading Chart on the following pages to determine the rate dial and linkage.

    Note: If the setting is not listed for the type of material being used, place the setting at a lower value then adjust as needed.

  3. Drive to the work area.

  4. Stop the machine on a level surface, leave motion control lever in the neutral position, stop the engine, and set the parking brake.

  5. Ensure that the hopper gate is closed.

  6. Remove the cover from the hopper, add the material to be spread, and replace the cover.

    Note: Do Not overload the hopper (refer to the Maximum Hopper Capacity in Specifications section).

    Note: Do Not exceed the Maximum Machine Weight as stated in the Specifications section. Overloading the machine will shorten the life of the transmission and void the warranty.

Spreading

Spreading Tips:

  • To ensure uniform application, be sure to overlap the material distribution. The highest amount of material will dispense from the front of the hopper and less material from each side. Adjust the distribution pattern to achieve desired results.

  • Watch for changes in the distribution pattern; unequal distribution may lead to striping.

Note: Make sure the machine has been calibrated properly before starting the spreading application.

  1. Start the engine and place the throttle midway between the “SLOW” and “FAST” positions.

  2. Set the impeller speed to appropriate broadcast rate setting.

  3. Move the throttle to the “FAST” position and drive forward.

  4. Pull the Spreader On/Off handle up to open the hopper gate and begin spreading.

    3. Side deflector lowered

  5. Evaluate the spread pattern. If adjustments are needed see the Spreader Calibration/Pattern Adjustment section.

  6. When finished spreading, close the hopper gate.

  7. Clean the hopper after each spreading session.

    Important: Always empty and clean the spreader immediately after each use. Failure to do so may cause the chemicals to corrode the spreader and other components.

Cleaning the Spreader

  1. Drive the machine to a designated cleaning area.

  2. Stop the machine on a level surface, leave the motion control lever in the neutral position, and turn off the engine. Engage the parking brake.

  3. With the hopper empty, push inward on the ball joint sleeve and pull off cable end to release the gate lever. Push the gate lever inward to fully open the drain hole.

    g027034

    Figure 17

    1. Gate lever
    2. Ball joint sleeve
    3. Rate dial and linkage

  4. Open the hopper gate to the maximum position by pulling the rate dial and linkage outward. Rotate the dial past the “9” position to the slot opening and push in the linkage.

  5. Using a garden hose, spray the inside and outside of the entire spreader with clean water.

    Note: Do Not use a power washer to clean the machine. The high pressure water may force residual corrosive materials into spreader components.

  6. When the hopper has been thoroughly rinsed and drained, close the gate.

  7. Place the rate dial and linkage to a setting lower than the maximum open position.

  8. Allow the spreader to completely dry before the next use.

  9. Lightly oil spreader components to help reduce corrosion.

Spreader Calibration

The spreader should be calibrated each time a new material is used. The spread width ranges from 3-25 ft (0.9-7.6 m) and depends on the material particle size, volume/density, and rate of travel.

Refer to the spreading charts along with Determining the Distribution Pattern, Determining the Effective Spreading Width, and Calculating the Application Rate sections to calibrate the machine.

Determining the Distribution Pattern

Important: The tines are rotating when the tines are lowered and the motion control lever is moved out of the neutral position. Make sure the tines are raised all the way up before starting this procedure.

Operator supplied equipment: 15 shallow collection pans and 15 graduated measuring cylinders

The most accurate method to measure the distribution is to use shallow collection pans and graduated measuring cylinders. In the example below, 15 shallow collection pans approximately 30 cm (12 inches) wide, 91 cm (36 inches) long, and 5 cm (2 inches) tall are used.

  1. Make sure to allow ample driving distance before setting up the pans to ensure the machine is traveling at the desired spreading speed before reaching the pans.

  2. Place one pan in the center of the drive path. Arrange the next two pans, one on each side, far enough apart to allow ample room for the spreader drive tires to pass over the center pan.

  3. Place the remaining pans in a straight line as shown in Figure 18 or Figure 19.

    • For larger granule materials:

      Space six additional pans, on each side, 12 inches (30 cm) apart (see Figure 19).

      g317337

      Figure 18

      1. Machine moving towards pans

      3. Collection pans (gap between each)
      4. 12 inch (30 cm) gap
      5. L1 and R1 collection pan gap (spread apart to allow machine to pass through)
      6. Graduated measuring cylinder

    • For smaller granule materials:

      Place six additional pans, on each side, with no gap in between each pan (Figure 19).

      g317338

      Figure 19

      1. Machine moving towards pans
      2. Center collection pan
      3. Left collection pans (no gap between each)
      4. Right collection pans (no gap between each)
      5. L1 and R1 collection pan gap (spread apart to allow machine to pass through)
      6. Graduated measuring cylinder

  4. Reference the Spreading Charts section to determine the appropriate rate dial setting (see Figure 7).

  5. Fill the hopper approximately half-full with the desired material.

  6. Set the impeller speed to the appropriate broadcasting rate.

  7. Pull the granular gate control to the open position and drive the spreader, at the appropriate speed, over the center pan. Repeat this several times, moving in the same direction each time, until enough material is dispensed to fill the center graduated measuring cylinder half full.

  8. Label each graduated measuring cylinder to correspond with the distribution pans (i.e. ...L2, L1, Center, R1, R2....) (reference Figure 18 and Figure 19).

  9. One at a time, take a collection pan and dump the contents into the corresponding graduated measuring cylinder. Record the amount of material collected and return the pan to its location. Repeat this until all pan contents have been emptied.

  10. With the graduated measuring cylinder in the same straight line as the pans, evaluate the volume of material in each cylinder to determine the quality of the distribution from the spreader.

  11. To adjust the spreader pattern, refer to the Spreader Pattern Adjustment section.

  12. Repeat steps 5 through 11 until an uniform pattern is achieved.

Determining the Effective Spreading Width

The effective width is used to determine the uniform distribution of the material.

Note: The spreading width range is 3 ft (0.9 m) up to 25 ft (7.6 m).

  1. After the spreader pattern is correctly adjusted, evaluate the amount of material in the center graduated measuring cylinder.

  2. Locate the two tubes, one each side of center, that contain 1/2 the measured amount of the material that you observed in the center graduated cylinder.

  3. Go to the two corresponding pans. Starting from the outer edge, measure and record the distance between left pan, through the center pan, to the outer edge of the right pan.

    Note: This measurement is the effective spreading width.

Calculating the Application Rate

  1. Determine the amount of product to be applied.

  2. Determine the calibration course

    1. Determine the amount of product to be spread per 1,000 ft2 (93 m2). Use the recommended rate from the Spreading Charts section or the product manufacturer’s label as a guide.

    2. Determine a course length by dividing 1,000 ft2 (93 m2) by the effective spread width.

      For example, if the effective width is 6 feet (1.8 meters), then the calibration course length equals 167 ft (51 m).

      Course Length

       1,000 ft2 (93 m2)=167 ft (51 m)
        6 ft (1.8 m)

    3. The calibration course is 6 ft (1.8 m) by 167 ft (51 m).

    4. Measure and visibly mark the course length. Make sure to allow ample distance before the starting marker to ensure the spreader is at full speed when crossing the first mark of the course.

  3. Set the appropriate gate dial setting (reference the Spreading Charts section as a starting point).

  4. Add material to the hopper (for example, 25 lb (11.3 kg) was added).

  5. Drive the spreader over the calibration course while applying the material.

  6. Empty the remaining material of the hopper into a clean bucket.

  7. Weigh the bucket containing the material and record the weight. Pour the contents back into the hopper and then weigh the empty bucket. Subtract these two amounts to determine the amount of material remaining in the hopper (for example, 20 pounds (9 kg) remains.)

  8. Subtract the amount remaining in the hopper (step 7) from the amount originally added (step 4); the result is the amount applied to the course.

    Amount Applied

    25 lb (11.3 kg) – 20 lb (9 kg)=5 lb (2.3 kg)

    For this example, 5 lb (2.3 kg) was applied to 1,000 ft2 (93 m2).

  9. If necessary, adjust the rate dial to achieve the recommended amount to be applied and repeat the procedure. Once the correct application rate is achieved, repeat this procedure an additional time to verify the results.

    Note: Designate a new calibration course each time, so the turf is not damaged.

Spreader Pattern Adjustment

If the spread pattern is skewed or dispensing too light/heavy to one side (see Figure 20 and Figure 21), adjust the gate as follows:

g025543

Figure 20

  1. Heavy to left side
  2. Move ramp pattern to shaded position
  3. Heavy to right side

Note: Do Not adjust the ramps to split product flow. Use only the front or rear ramp positions as shown.

  1. Unlock the spreader pattern control by turning the handle counterclockwise 90 degrees (see Figure 21).

    To adjust when the material pattern is heavy:

    • to the left side, slightly push the handle down.

    • to the right side, slightly pull the handle up.

After Operation

General Safety

  • Park machine on level ground, disengage drives, set parking brake, stop engine, and remove key. Wait for all moving parts to stop before leaving the operator’s position. Allow the machine to cool before servicing, adjusting, fueling, unclogging, cleaning, or storing.

  • Clean grass, leaves, excessive grease or oil, and other debris from the muffler, drives, and engine area to help prevent fires.

  • Close the fuel shut-off valve before storing or transporting the machine.

Transporting

Note: Refer to the chemical warning product label(s) before transporting the machine and follow all local/state/federal requirements for transporting chemicals.

Note: Make sure the spreader hopper cover is secure before transporting.

Transporting the Machine

Use a heavy-duty trailer or truck to transport the machine. Ensure that the trailer or truck has all necessary lighting and marking as required by law. Thoroughly read all of the safety instructions. Knowing this information could help you, your family, pets, or bystanders avoid injury.

To transport the machine:

  • Lock the brake and block the wheels.

  • Securely fasten the machine to the trailer or truck with straps, chains, cable, or ropes. If possible, both front and rear straps should be directed down and outward from the machine. Only use the four designated tie-down locations on the machine-two on the left side and two on the right (see Figure 27). Use these locations even when transporting the machine with an attached accessory. Using non-designated locations may cause damage to the machine and/or attachment.

    g317044

    Figure 27

    1. Tie-down location

  • Secure a trailer with safety chains.

    Warning

    Securing the machine on any upper frame location will cause the parking brake to not function properly, which could cause serious injury or death.

    Only use the front tie down locations on the lower frame to secure the machine.

    Warning

    Driving on the street or roadway without turn signals, lights, reflective markings, or a slow moving vehicle emblem is dangerous and can lead to accidents causing personal injury.

    Do not drive machine on a public street or roadway.

Loading the Machine

Use extreme caution when loading machines on trailers or trucks. One full width ramp that is wide enough to extend beyond the rear tires is recommended instead of individual ramps for each side of the machine. A full width ramp provides a surface to walk on behind the machine. If it is not possible to use one full width ramp, use enough individual ramps to simulate a full width continuous ramp.

A steep ramp angle may cause components to get caught as the machine moves from ramp to trailer or truck. Steeper angles may also cause the machine to tip backward. If loading on or near a slope, position the trailer or truck so it is on the down side of the slope and the ramps extends up the slope. This will minimize the ramp angle. The trailer or truck should be as level as possible.

Important: Do Not attempt to turn the machine while on the ramp, you may lose control and drive off the side.

Avoid sudden acceleration when driving up a ramp and sudden deceleration when backing down a ramp. Both maneuvers can cause the machine to tip backward.

Warning

Loading a machine on a trailer or truck increases the possibility of backward tip-over. Backward tip-over could cause serious injury or death.

  • Use extreme caution when operating a machine on a ramp.

  • Use only a single, full width ramp; Do Not use individual ramps for each side of the machine.

  • If individual ramps must be used, use enough ramps to create an unbroken ramp surface wider than the machine.

  • Avoid sudden acceleration while driving machine up a ramp to avoid tipping backward.

  • Avoid sudden deceleration while backing machine down a ramp to avoid tipping backward.

Maintenance

Note: Determine the left and right sides of the machine from the normal operating position.

Maintenance Safety

  • Park machine on level ground. Raise the tines, close the spreader gate, set the parking brake, stop engine and remove key or disconnect spark plug wire. before servicing, adjusting, fueling, unclogging, cleaning, or storing.

  • If you leave the key in the switch, someone could accidently start the engine and seriously injure you or other bystanders. Remove the key from the switch before you perform any maintenance.

  • Never allow untrained personnel to service machine.

  • Disconnect battery or remove spark plug wire before making any repairs. Disconnect the negative terminal first and the positive last. Reconnect positive first and negative last.

  • Empty the hopper before tilting the machine for maintenance and before storing.

  • Keep all guards, shields, switches, and all safety devices in place and in proper working condition. Frequently check for worn or deteriorating components and replace them with genuine Z Turf Equipment parts when necessary.

    Warning

    Removal or modification of original equipment, parts and/or accessories may alter the warranty, controllability, and safety of the machine. Unauthorized modifications to the original equipment or failure to use original Z Turf Equipment parts could lead to serious injury or death. Unauthorized changes to the machine, engine, fuel or venting system, may violate applicable safety standards such as: ANSI, OSHA and NFPA and/or government regulations such as EPA and CARB.

    Warning

    Hydraulic fluid escaping under pressure can penetrate skin and cause injury. Fluid accidentally injected into the skin must be surgically removed within a few hours by a doctor familiar with this form of injury or gangrene may result.

    • If equipped, make sure all hydraulic fluid hoses and lines are in good condition and all hydraulic connections and fittings are tight before applying pressure to hydraulic system.

    • Keep body and hands away from pinhole leaks or nozzles that eject high pressure hydraulic fluid.

    • Use cardboard or paper, not your hands, to find hydraulic leaks.

    • Safely relieve all pressure in the hydraulic system by placing the motion control levers in neutral and shutting off the engine before performing any work on the hydraulic system.

  • Use care when checking and servicing tines. Wrap the tine(s) or wear gloves, and use caution when servicing them. Only replace damaged tines. Never straighten or weld them.

  • Do not rely solely on mechanical or hydraulic jacks for support. Use adequate jack stands.

  • Carefully release pressure from components with stored energy.

  • Keep your hands and feet away from moving parts or hot surfaces. If possible, do not make adjustments with the engine running.

  • Keep all parts in good working condition and all hardware tightened, especially the tine-attachment hardware.

    Important: Do Not operate the engine with the oil level below the “LOW” (or “ADD”) mark on the dipstick, or over the “FULL” mark.

    Check Battery Charge

    Maintenance Service IntervalMaintenance Procedure
    Monthly
  • Check the battery charge.
    		•

    Allowing batteries to stand for an extended period of time without recharging them will result in reduced performance and service life. To preserve optimum battery performance and life, recharge batteries in storage when the open circuit voltage drops to 12.4 volts.

    Note: To prevent damage due to freezing, battery should be fully charged before putting away for winter storage.

    Charge batteries in an open well ventilated area, away from spark and flames. Unplug charger before connecting or disconnecting from battery. Wear protective clothing and use insulated tools.

    Danger

    Charging or jump starting the battery may produce explosive gases. Battery gases can explode causing serious injury.

    • Keep sparks, flames, or cigarettes away from battery.

    • Ventilate when charging or using battery in an enclosed space.

    • Make sure venting path of battery is always open once battery is filled with acid.

    • Always shield eyes and face from battery.

    Danger

    Battery electrolyte contains sulfuric acid, which is poisonous and can cause severe burns. Swallowing electrolyte can be fatal or if it touches skin can cause severe burns.

    • Wear safety glasses to shield eyes, and rubber gloves to protect skin and clothing when handling electrolyte.

    • Do Not swallow electrolyte.

    • In the event of an accident, flush with water and call a doctor immediately.

    Caution

    If the ignition is in the “ON” position there is potential for sparks and engagement of components. Sparks could cause an explosion or moving parts could accidentally engage causing personal injury.

    Be sure ignition switch is in the “OFF” position before charging the battery.

    Check the voltage of the battery with a digital voltmeter. Locate the voltage reading of the battery in the table and charge the battery for the recommended time interval to bring the charge up to a full charge of 12.6 volts or greater.

    Important: Make sure the negative battery cable is disconnected and the battery charger used for charging the battery has an output of 16 volts and 7 amps or less to avoid damaging the battery (see chart for recommended charger settings).

    Voltage ReadingPercent ChargeMaximum Charger SettingsCharging Interval

    Recommended Jump Starting Procedure

    1. Check the weak battery for terminal corrosion (white, green, or blue “snow”), it must be cleaned off prior to jump starting. Clean and tighten connections as necessary.

      Caution

      Corrosion or loose connections can cause unwanted electrical voltage spikes at anytime during the jump starting procedure.

      Do Not attempt to jump start with loose or corroded battery terminals or damage to the engine may occur.

      Danger

      Jump starting a weak battery that is cracked, frozen, has low electrolyte level, or an open/shorted battery cell, can cause an explosion resulting in serious personal injury.

      Do Not jump start a weak battery if these conditions exist.

    2. Make sure the booster is a good and fully charged lead acid battery at 12.6 volts or greater. Use properly sized jumper cables (4 to 6 AWG) with short lengths to reduce voltage drop between systems. Make sure the cables are color coded or labeled for the correct polarity.

      Caution

      Connecting the jumper cables incorrectly (wrong polarity) can immediately damage the electrical system.

      Be certain of battery terminal polarity and jumper cable polarity when hooking up batteries.

      Note: The following instructions are adapted from the SAE J1494 Rev. Dec. 2001 – Battery Booster Cables – Surface Vehicle Recommended Practice (SAE – Society of Automotive Engineers).

      Warning

      Batteries contain acid and produce explosive gases.

      • Shield the eyes and face from the batteries at all times.

      • Do Not lean over the batteries.

      Note: Be sure the vent caps are tight and level. Place a damp cloth, if available, over any vent caps on both batteries. Be sure the vehicles do not touch and that both electrical systems are off and at the same rated system voltage. These instructions are for negative ground systems only.
