  10. A 10 amp fuse is included in the harness. If using a 4 wheel brake kit, replace the 10 amp fuse with the provided 15 amp fuse.

Setting the Electric Brake Adjustments

Before operating the machine for the first time, the electric brakes must be synchronized to the tow vehicle’s brakes (so that they operate at the same time).

The machine and the tow vehicle will seldom have the correct amperage flow to the brake magnets to provide comfortable, safe braking. Changing the load weight, as well as uneven alternator and battery output, can result in unstable current flow to the brake magnets.

The Brake Control compensates for trailer load variations by limiting the maximum torque output of the brakes by adding dropping resistance in the electrical control line. When towing a trailer loaded to brake rated capacity, the Brake Control must be set at maximum braking. When pulling an empty or partially loaded trailer, the Brake Control must be set between maximum and minimum braking at a position just before the point at which trailer tire skidding occurs when actuating the hand control fully on. Failure to install and use the Electric Brake Control will result in excessive brake torque when stopping a trailer loaded to less than brake capacity.

Assembling the Handheld Remote (Model 44954 only)

Parts needed for this procedure:

Handheld remote1
AA batteries4
Magnetic bracket1
Screws, small6

  1. Remove the rubber bands securing the remote halves together, and remove the back cover.

  2. Plug each battery into a terminal cradle observing proper polarity. (If the batteries are improperly installed, the unit will not be damaged, but it will fail to operate.) The cradle is embossed with polarity markings for each terminal (Figure 12).

Operation

Before Operation

Before Operation Safety

  • The machine has different balance, weight, and handling characteristics compared to some other types of towed equipment. Read and understand the contents of this Operator's Manual before operating the machine. Become familiar with all controls and know how to stop quickly.

  • Never allow children to operate the machine. Do not allow adults to operate the machine without proper instructions. Only trained and authorized persons should operate this machine.

  • Keep all shields and safety devices in place. If a shield, safety device or decal is illegible or missing, repair or replace it before operating the machine.

  • The machine is designed only for off-road use. The maximum recommended speed is 24 km/h (15 mph) without a load and 13 km/h (8 mph) with a full load.

  • Tighten any loose nuts, bolts, and screws to ensure that the machine is in safe operating condition. Ensure that the machine tongue mounting pins, hitch pins, and tongue jack are in place and secure.

  • Do not modify this equipment in any manner.

  • The tongue is the area on the machine where the hitch connects to the tow vehicle. The weight of the tongue affects the stability of the machine.

    • A negative or positive tongue weight can cause injury when connecting or disconnecting the machine to the tow vehicle. When installed, ensure that the jack-stands are properly engaged.

    • When the weight of the tongue is forced up into the hitch of the tow vehicle, this produces a negative tongue weight.

      Negative tongue weight may also result when attachments are mounted on the rear of the machine.

    • When the weight of the tongue is forced down onto the hitch of the tow vehicle, this produces a positive tongue weight.

  • Never attach the machine to or remove the machine from the traction unit if there is material in the hopper. The tongue may flip up, causing injury.

Connecting the Machine to the Tow Vehicle

  1. Connect the machine hitch to the tow vehicle using a 25 mm (1 inch) diameter safety approved hitch pin and safety clip (not supplied).

    Important: Use a high strength hitch pin that is approved for tow vehicle hitches.

  2. Adjust the hitch height by turning the jack stand handle to keep the machine level.

  3. Lower the hitch using the jack stand.

  4. When the full weight of the machine has been transferred to the tow vehicle’s draw bar from the jack stand, pull the pin holding the jack stand in place.

  5. Turn the jack stand 90 degrees counter clockwise until the bottom of the jack stand points to the rear of the machine. This is the traveling position.

    Caution

    Raise the jacks into the traveling position before towing the machine.

  6. Connect the two hydraulic hoses from the machine to the tow vehicle. Facing the front of the machine, connect the right hose to the pressure side and the left hose to the return side (Figure 20). The return hose has an in line one way check valve. The arrow on the check valve should face the tow vehicle return connector.

    g014116

    1. SH Power harness

  8. Connect the coiled, power cable to the socket on the machine and the tow vehicle (Figure 11).

  9. Check the hydraulic oil level in the tow vehicles tank and add more to fill it, if necessary. (See the tow vehicle’s Owner’s Manual).

  10. Test the hydraulics before operating the machine for the first time.

  11. Set the electric brake (if so equipped) as follows:

    • Before operating the machine for the first time, the electric brakes must be synchronized to the tow vehicle’s brakes (so that they operate at the same time).

    • The machine and the tow vehicle will seldom have the correct amperage flow to the brake magnets to provide comfortable, safe braking. Changing the load weight, as well as uneven alternator and battery output, can result in unstable current flow to the brake magnets.

    • The Load Control compensates for trailer load variations by limiting the maximum torque output of the brakes by adding dropping resistance in the electrical control line. When towing a trailer loaded to brake rated capacity, the Brake Control must be set at maximum braking. When pulling an empty or partially loaded trailer, the Brake Control must be set between maximum and minimum braking at a position just before the point at which trailer tire skidding occurs when actuating the hand control fully on. Failure to install and use the Electric Brake Control will result in excessive brake torque when stopping a trailer loaded to less than brake capacity.

    Caution

    If you hear a noise from the tow vehicle hydraulics and the machine controls do not operate, the hoses have been connected incorrectly and must be reversed.

    Note: You may have to relieve the pressure in the hoses of the machine connecting to the tow vehicle, to ensure a completed connection.

    Important: When making sharp turns, the hydraulic hoses may contact the tow vehicle wheels. Avoid making sharp turns, if necessary, use a bungee cord (a rubber strap with hooks on both ends) to pull back the hoses toward the center.

Loading Material

Load the machine from the top or from the rear.

For most materials, such as sand or gravel, you can use a front end bucket loader. For materials such as landscaping ties or fertilizer bags, load from the rear by placing the material on the conveyor belt and setting the hydraulics in the load position.

You may need to remove the rear gate for easier access.

If sacks of material are being used, empty the sacks into the loader’s bucket before loading the material into the hopper. To ensure stability, distribute the load evenly, front to back and side to side.

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

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

  • Keep your hands and feet out of the hopper while the machine is operating, or while the engine is running on the tow vehicle.

  • Remain seated whenever the tow vehicle is in motion.

  • Using the machine demands attention. Failing to operate tow vehicle safely may result in an accident, tip-over of the tow vehicle, and serious injury or death. Drive carefully, and to prevent tipping or loss of control, do the following:

    • Use extreme caution, reduce the speed, and maintain a safe distance (twice the width of the machine) around sand traps, ditches, water hazards, ramps, unfamiliar areas, or other hazards.

    • Reduce the speed of a loaded machine when negotiating terrain undulations to avoid causing the machine to become unstable.

    • Watch for holes or other hidden hazards.

    • Use caution when operating on a slope. Travel straight up and down slopes. Reduce speed when making sharp turns or when turning on hillsides. Avoid turning on hillsides whenever possible.

    • Use extra caution when operating on wet surfaces, at higher speeds or with a full load. Stopping time increases with a full load. Shift into a lower gear before starting up or down a hill.

    • Avoid sudden stops and starts. Do not go from reverse to forward or forward to reverse without coming to a complete stop.

    • Do not attempt sharp turns or abrupt maneuvers or other unsafe driving actions that may cause a loss of control.

    • Be aware of your surroundings when turning or backing up the machine. Ensure that the area is clear and keep all bystanders out of the operating area. Proceed slowly.

    • Watch out for traffic when near or crossing roads. Always yield the right of way to pedestrians and other vehicles. Obey all traffic rules and check for local regulations on the operation of the machine on or near highways.

    • Always watch out for and avoid low overhangs such as tree limbs, door jambs, overhead walkways, etc. Ensure that there is enough room over head to easily clear the tow vehicle and your head.

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

    • If you are ever unsure about safe operation, stop working and ask your supervisor.

    • Do not leave the machine unattended while it is running.

  • Ensure that the machine is connected to the tow vehicle before loading.

  • Do not carry loads that exceed the load limits of the machine or the tow vehicle.

  • The stability of loads can vary—for example, high loads have a higher center of gravity. Reduce the maximum load limits to ensure better stability, if necessary.

  • To avoid causing the machine to tip over, do the following:

    • Carefully monitor the height and weight of the load. Higher and heavier loads can increase the risk of tipping.

    • Distribute the load evenly, from front to back and side to side.

    • Be careful when turning and avoid unsafe maneuvers.

    • Always ensure that the machine is connected to the tow vehicle before loading.

    • Do not put large or heavy objects into the hopper. This could damage the belt and rollers. Also ensure that the load has a uniform texture. Small rocks in the sand can become projectiles.

  • Do not stand behind the machine when unloading or spreading. The optional twin spinner, cross conveyor, and processor can eject particles and dust at a high speed.

  • Unload the machine or disconnect it from the tow vehicle while on a level surface.

  • Ensure that the machine is connected to the tow vehicle before unloading.

  • Do not travel with the machine in the fully raised position. This increases the risk of tipping over the machine.

  • The machine has a safe range for traveling with attachments as shown by the green section in the decal.

  • Do not travel with the machine in the caution range (yellow/black). When there are no attachments on the machine, travel with the machine in the lowered position.

  • Shut off the machine when approaching people, vehicles, vehicle crossings, or pedestrian crossings.

  • Do not operate the machine with the weight case removed or out of position.

  • When equipped, hydraulic trailer brakes may overheat the fluid in the hydraulic circuit if the brakes remain activated continuously. Always use a lower speed gear selection when descending long hills. Activate the brakes intermittently to allow for cooling cycles for both the vehicle and the topdresser.

Slope Safety

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

  • Evaluate the site conditions to determine if the slope is safe for machine operation, including surveying the site. Always use common sense and good judgment when performing this survey.

  • Review the slope instructions listed below for operating the machine on slopes and to determine whether you can operate the machine in the conditions on that day and at that site. Changes in the terrain can result in a change in slope operation for the machine.

  • Use extreme caution when traveling on hills, especially when turning.

    • Traveling across hills with the machine could result in a tip-over, or a loss of traction for the traction unit or the machine.

    • Always travel straight up and down hills—do not travel sideways or diagonally. When traveling down a hill, do not exceed the speed at which you can travel up the same hill. Stopping distance increases when traveling down hills.

    • Reduce the weight of the load when traveling on steep hills and avoid piling the load high.

  • Identify hazards at the base of the slope. Use extreme caution when operating 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.

  • 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.

  • 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.

  • 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.

  • Always keep the traction unit in gear when going down slopes. Do not coast downhill (applicable only to gear-drive units).

Turning the Machine Power On/Off

When finished working with the machine, always press the E-STOP button (Figure 23) to disable the electrical system. When beginning work with the machine, you must pull the E-STOP button back out before turning on the handheld remote.

  • To load the machine, push the control lever away from you. This moves material to the front along the conveyor belt.

  • To stop the conveyor belt, move the control lever to the center position.

Center Valve

The center valve raises and lowers the machine.

  • To raise the machine, pull on the control lever until the desired height is reached, then release it.

  • To lower the machine, push on the control until the desired height is reached, then release it.

    Caution

    Do not keep holding the control lever in the raised or lowered position once the lift cylinders have reached their maximum travel position.

Right Valve

The right valve controls the option.

  • To turn on the option, pull on the control lever.

  • To turn off the option, return the control lever to the center position.

    Warning

    Pushing the control lever does not have any function. Options cannot be reversed.

    Important: Do not pull the option lever into the On position without an option mounted. This can damage the floor motor and stop the machine.

Operating the Hydraulic Controls and Options on EH Models

Manual Override (Model 44594)

Should the remote ever be lost, damaged or fail, the machine functions and operation are still possible in order to complete tasks or continue work until the problem is resolved.

The override access is on the driver side of the hydraulic system (Figure 26).

g297178

Figure 26

  1. Floor speed
  2. Raise/lower hopper
  3. Spinner speed

  • To adjust the floor speed (Figure 26), turn the knob clockwise. Maximum floor speed is used in the Color-Coded Operating System so this adjustment can be made while no hydraulic flow is present. This is most relevant when you have a hopper full of sand.

    decal119-6832

    Figure 27

    1. Adjust floor speed
    2. Lower the hopper
    3. Raise the hopper
    4. Adjust spinner speed

  • To raise the hopper (Figure 26), push in on the ring on the valve stem.

  • To lower the hopper (Figure 26), pull out on the ring on the valve stem.

  • To adjust the spinner speed (Figure 26), use a flat-head screwdriver to increase by turning clockwise or decrease by turning counter clockwise.

Note: If adjusting with the hydraulic flow active, ensure that the floor is turned off if you do not wish to have sand being spread as you adjust.

Once your settings are acceptable, use the hydraulic flow control on your tow vehicle to turn the system on and off for operation.

Key Functionality Elements

  • When the handheld remote is first powered on, the display should read FLR OFF and OPT OFF in approximately 5 seconds. If the words “waiting for base” are in the display, check to ensure there is electrical power to the base unit and ensure the E-STOP button on the base unit is pulled out.

  • There is always a current working memory. This is not the same as a preset. The last saved work settings will be in the current working memory when the handheld remote is powered on.

  • Operational sequence of the handheld remote start buttons:

    • Pressing a start button once (ALL START, FLOOR START, or OPTION START) calls up the current working memory setting stored in the handheld remote.

    • By pressing the same start button a second time the component turns on if the hydraulics are engaged (it shows numbers ramping up in the display).

    • Pressing the same start button a third time will store the new setting established in the remote’s working memory.

  • After pressing a start button once to view the current working memory setting in a non-working mode, there is approximately 10 seconds to begin adjusting the setting or the element will revert back to off. In a working mode, the 10 second rule is gone.

  • To program a preset, the key to remember is the elements must be activated or engaged.

  • To operate from a preset, the element speed percentages must be in the display to activate or engage them. If the words OFF are in the display, the preset must be recalled.

Manually Overriding the Hydraulic Controls

EH Models

If the handheld remote is missing, damaged, or fails, you can still operate the machine to complete tasks or continue a spreading job.

Preparing the Machine

  1. At the right side of the machine, remove the 4 flange-head capscrews that secure the cover plate to the override cover (Figure 28).

Graphic + Graphic

Note: There are three settings: OFF, LOW, and HIGH.

To Decrease the Backlighting:

Hold the ALL STOP and the FLOOR DECREASE buttons simultaneously while observing the display until the backlighting is as desired.

Graphic + Graphic

Note: There are three settings: OFF, LOW, and HIGH. Backlighting consumes the most energy of all Handheld Remote functions. Increasing the backlighting increases power consumption and will shorten the life span of the batteries; the lower the backlighting, the longer the battery life span.

Understanding the Remote Status LED

The remote status LED blinks slowly at 2 Hz (twice per second) when the handheld remote is transmitting but no buttons are being pressed, when the floor and option buttons active. When you press a button, the light will blink at 10 Hz.

Replacing the Remote Batteries

The handheld remote is powered by 4, AA Alkaline batteries (1.5 V each) and operates between 2.4 to 3.2 V. Battery life is approximately 300 hours (continuous operation with the backlight off), but battery life longevity is affected by usage factors, particularly backlight intensity setting—the higher the backlight setting, the more power consumed resulting in shorter battery life.

Important: Keep fresh spare batteries at hand at all times that the system is in use.

  1. Loosen the bolt in the magnet on the magnetic remote bracket (Figure 37).

    g028874

    Figure 37

  4. Remove the discharged batteries and properly dispose in accordance with local regulations.

  5. Plug each fresh battery into a terminal cradle observing proper polarity. (If the batteries are improperly installed, the unit will not be damaged, but it will fail to operate.) The cradle is embossed with polarity markings for each terminal (Figure 38).

  6. If you accidentally removed the rubber seal and the steel gasket, replace them carefully into the channel in the handheld remote (Figure 38).

  7. Replace the cover and secure it with the 6 screws removed previously (Figure 38) and torque them to 1.5 to 1.7 N-m (13 to 15 in-lb).

  8. Install the handheld remote into the magnetic remote bracket, slide the halves together to secure the remote, and tighten the bolt in the magnet (Figure 37).

Caring for the Handheld Remote

Though the handheld remote is rugged, care should be taken not to drop the unit onto hard surfaces. To clean it, use a soft cloth moistened with water or a mild cleaning solution to wipe it paying particular attention to avoid scratching the LCD screen.

Associating the Handheld Remote with the Base

The factory initially associates the remote to the base allowing them to communicate; however, there may be instances in the field when you must reassociate a remote and a base unit, as follows:

  1. Press the E-Stop button to remove power from the base unit and make sure the handheld is off.

  2. Stand near the base unit in clear line of sight.

  3. Simultaneously press and continue to hold the ON/OFF and the ALL STOP buttons.

    Graphic + Graphic

    The handheld remote goes through its initialization screens and settles on ASSOC PENDING.

As you hold the buttons down, the display cycles approximately every 2 seconds displaying first the battery life expectancy in percent remaining or current battery voltage, the operating frequency (channel) on which the units communicate, then the handheld remote ID number, and finally the associated BASE Unit ID.

Operating the Floor and Option

Use the following procedures to set and operate the machine floor and option (such as the twin spinner or other attachment) as follows:

  • Setting and operating the floor alone

  • Setting and operating the option alone

  • Setting and operating both floor and option together

Setting and Operating the Floor Alone

Upon initially pressing the FLOOR START button Graphic (when the floor is not running), the remote display shows the stored setting and an S is displayed after FLR (i.e. FLRS), indicating that the remote is in a set-only mode. In this set-only mode, you can adjust the setting up or down, but the floor does not activate, remaining off. This allows you to set a desired floor speed or use the stored setting without causing unwanted movement. After setting the speed, press the FLOOR START button to activate the floor at the chosen setting (if the hydraulics are engaged, the floor will start). Press FLOOR START a third time to store the current value in memory.

Note: Changes to the foor settings while the floor is running are immediately effective, but they are temporary unless you store the new setting by pressing FLOOR START again after changing the setting. For instance, you make an adjustment while the display shows FLRS, press Floor Start starting the floor at the adjusted setting, and then turn the remote off without pressing FLOOR START again, storing the change. The next time you use the remote, the setting will revert to the previously stored value.

Note: A 10 second timer starts when you press FLOOR START and FLRS (set-only mode) displays. If you do not press a button during the 10 second interval, the display reverts to FLR and the previous state/value displays and is enforced. The timer resets to ten seconds if any button is pressed while the remote is in the set-only.

  1. Press the FLOOR START button.

    The display shows FLOOR STORE. The set value will be used whenever the floor is started in the future until you change the setting again.

Setting and Operating the Option Alone

Upon initially pressing the OPTION START button Graphic (when the option is not running), the remote display shows the stored setting and an S is displayed after OPT (i.e. OPTS), indicating that the remote is in a set-only mode. In this set-only mode, you can adjust the setting up or down, but the option does not activate, remaining off. This allows you to set a desired option speed or use the stored setting without causing unwanted movement. After setting the speed, press the OPTION START button to activate the option at the chosen setting (if the hydraulics are engaged, the option will start). Press OPTION START a third time to store the current value in memory.

Note: Changes to the option settings while the option is running are immediately effective, but they are temporary unless you store the new setting by pressing OPTION START again after changing the setting. For instance, you make an adjustment while the display shows OPTS, press OPTION START starting the option at the adjusted setting, and then turn the remote off without pressing OPTION START again, storing the change. The next time you use the remote, the setting will revert to the previously stored value.

Note: A 10 second timer starts when you press OPTION START and FLRS (set-only mode) displays. If you do not press a button during the 10 second interval, the display reverts to FLR and the previous state/value displays and is enforced. The timer resets to ten seconds if any button is pressed while the remote is in the set-only.

    The display shows OPTION STORE. The set value will be used whenever the option is started in the future until you change the setting again.

Setting and Operating the Floor and Option Together

Upon initially pressing the ALL START button Graphic (when the option is not running), the remote display shows the floor and option stored settings and an S is displayed after FLR and OPT (i.e. FLRS and OPTS), indicating that the remote is in a set-only mode. In this set-only mode, you can adjust either setting up or down, but the floor and option do not activate, remaining off. This allows you to set the desired speeds or use the stored settings without causing unwanted movement. After setting the speeds, press the ALL START button to activate the floor and option at the chosen setting (if the hydraulics are engaged, the floor and option will start). Press ALL START a third time to store the current value in memory.

Note: Changes to the settings while the floor and option are running are immediately effective, but they are temporary unless you store the new setting by pressing ALL START again after changing the setting. For instance, you make an adjustment while the display shows FLRS and OPTS, press ALL START starting the floor and option at the adjusted setting, and then turn the remote off without pressing ALL START again, storing the change. The next time you use the remote, the settings will revert to the previously stored values.

Note: A 10 second timer starts when you press ALL START and set-only mode displays. If you do not press a button during the 10 second interval, the display reverts to FLR and OPT and the previous state/value displays and is enforced. The timer resets to ten seconds if any button is pressed while the remote is in the set-only.

    Note: Both the floor and option must be running to store the settings using the ALL START button. If only one or neither are running, pressing the ALL START button will either start them both or start the one that was not running. Nothing is stored and the commands previewed are the previously stored floor and the option settings.It is important to realize that the stored command for the floor and option are used twice, once in the event of an individual command using the FLOOR START or OPTION START buttons, and once in the event of a combined action using ALL START; in either case, it is the same number.

Setting the Preset 1, 2, and 3 Buttons

The remote has three PRESET buttons which you can program with floor and option speed settings. Each PRESET button acts like a preview mode for the ALL START button, except that they use different, user defined quick reference speed values.

If the floor and/or the option happen to be running at the time you press a PRESET button, a preview value of both floor and option settings is displayed; if you then press the ALL STARTbutton, the current operating values are replaced by the preset values. If you do not press the ALL-START button within 10 seconds, the system will revert back to the previously stored values.

Use the following procedure to set the values of a PRESET button:

  1. Start both the floor and option either individually or by using the ALL START button .

    Graphic

  2. Set the desired speeds of both floor and option by using the appropriate INCREASE and DECREASE speed buttons for each output.

  3. Press and hold the STORE button and then press the desired PRESET button (1, 2, or 3).

    Graphic then Graphic, Graphic, or Graphic

    The screen will display PRESET SAVED.

  8. Re install the tire onto the machine by reversing the above steps.

    Note: Ensure that the wheel is centered on the hub and all six wheel bolts and the bearing bolts are tight to 135 N-m (100 ft-lb).

Tracking the Conveyor Belt

If the conveyor belt is not centered and tracks to one side, it needs to be adjusted (Figure 58). The best time to do this is between loads during operation.

  1. Go to the rear of the machine and determine which side of the belt is touching.

  2. Go to the front on the same side, loosen the locking nut, and tighten the adjuster nut by one quarter turn.

  3. Tighten both locking nuts before running the machine.

  4. Load the machine with material and run the load through until empty. Repeat multiple times.

  5. Stop the belt and go to the rear of the machine to observe the results.

    You may need to repeat the above steps several times until the belt begins to move and track properly.

    Note: The belt may move slightly depending on the type of load and its position. If the belt is not touching the side rails, you do not need to track the belt.

    Important: Do not adjust the belt’s rear drive roller. It is set to factory specifications. Contact your authorized Toro distributor if adjustment is required.

Tensioning the Conveyor Belt

Check and adjust the belt tension frequently (Figure 58). All rubber conveyor belts will stretch, especially when they are new or have not been used for awhile.

  1. Park the machine on level ground with the rear gate and feed gate at least 6.25 mm (1/4 inch) off the floor (depending on the material).

  2. Fully load the machine with sand that you expect the machine to use.

  3. Remove the black front covers on either side of the machine.

  4. Using two wrenches, hold the end of the tensioner rod stationary, while loosening the locking nut closest to the end of the rod.

  5. Move the locking nut back 2–5 cm (1–2 inches).

    Warning

    Use extreme caution around moving parts with safety guards removed.

  6. Turn on the conveyor belt.

  7. If belt slips, tighten the tension bolts evenly (with machine off) half a turn and recheck. Continue until the belt moves without any slippage.

  8. Give both tensioning bolts another half turn. At this point you should have proper tension.

  9. To verify, look underneath at the chassis cross member. The middle of the belt should just clear the chassis cross member when the machine is in the down position. If the middle of the belt is touching the cross member, tighten both tensioning bolts another quarter of a turn.

    Important: Be patient. Do not over-tension the belt.

    Important: Do not use air tools on the belt tensioning bolts.

Changing the Conveyor Belt

Read these instructions before removing the belt. If the belt is completely destroyed, simply use a knife to cut the belt in an undamaged area. If you intend to make a warranty claim, the belt supplier must inspect the belt to evaluate the damage and make recommendations for replacement.

Removing the Belt

  1. Remove the black safety covers located on the four outer corners of the machine.

  2. Remove the guides for the inner rubber liner from the front and both sides of the hopper, with the metal rails attached.

  3. Remove the silicone sealer on the rear of the metal rails (but remember to re apply the silicone sealer when re installing them).

  4. At both front corners, use two wrenches to hold the end of the tensioner rod stationary.

  5. Loosen the nut closest to the end of the tensioning rod.

  6. Move the inside adjusting nut back until the tensioning rod clears the pillow block bearing.

    Note: The front idler roller is supported by two pillow block bearings sitting in an upper and lower guide (one set on each side of the machine).

  7. Support the front idler roller.

  8. Go to the right front corner and remove the locking collar that holds the pillow block bearing on the shaft. Do this by backing off the set screws and turning the locking collar counterclockwise. Using a hammer and punch, tap the locking collar counterclockwise until it releases from the shaft.

  9. Repeat this step for the left front corner.

  10. Remove the pillow block bearings by sliding the idler roller back so the pillow block bearings slide out of their guides.

  11. Remove the two safety brackets and slide the roller down through the open hole.

  12. Go to the rear of the machine and loosen the tensioning sprocket.

  13. Remove the chain from the drive sprocket.

Note: Before sliding the rear drive roller back up through the slot and into place, ensure that you have already installed the four bolts (from the inside facing out) for connecting the pillow block bearings. Otherwise, you will have to remove the drive roller to gain enough clearance to install these bolts.

When installing the rear drive roller, ensure that the shaft connecting to the motor is on the left side. It has a keyhole cut into it for securing the drive sprocket.

Before applying tension with the tensioner rods at the front of the machine, use your hands to manually center the belt at the front and rear.

Track and tension the belt by following the instructions in the Maintenance Section of the manual.

The front idler and rear drive rollers provide excellent traction for pulling the belt under load, so do not overtighten or stretch the belt.

Apply silicone sealer to the rear side of the metal rails and at the two front corners of the floor where the rails meet. The sealer deflects any material from getting past the rails.

Adjusting the Conveyor Drive Chain

If the conveyor drive chain is loose, it needs to be tightened (Figure 62).

  1. Turn off the tow vehicle and set the parking brake.

  2. Remove the rear conveyor drive guard.

  3. Loosen the bolt that goes through the tensioner sprocket.

  4. Tighten the positive locking screw using moderate force.

  5. Tighten the tensioner sprocket bolt.

  6. Check that the chain is sufficiently lubricated and the sprockets are secure to the shafts.

  7. Replace the rear conveyor drive guard.

    Caution

    Do not over tension the chain. Leave just enough tension to take up the extra slack.

Maintaining the Electric Brakes

Inspecting the Electric Brakes

Once a month, conduct a simple visual inspection of your brake shoes and linings.

Inspect and service your electric brakes once a year.

Adjusting the Electric Brakes

Adjust the electric brakes after the first three months of operation, or sooner depending on use or performance.

  1. Jack up the machine securely.

  2. Ensure that the wheel and drum rotate freely.

  3. Remove the adjusting hole cover from the slot on the bottom of the brake backing plate.

  4. With a screwdriver, rotate the star wheel of the adjuster assembly to expand the brake shoes (Figure 63).

    g014826

    Figure 63

    1. Screwdriver

  5. Adjust the brake shoes out until the pressure of the linings against the drum makes the wheel difficult to turn.

  6. Rotate the star wheel in the opposite direction until the wheel turns freely with a slight drag on the lining.

  7. Replace the adjusting hole cover.

  8. Repeat the above procedure on each brake.

Inspecting the Brake Shoes and Linings

Once a month, conduct a simple visual inspection of your brake shoes and linings.

When a brake shoe becomes worn, replace both shoes on each brake, and both brakes on the same axle. This ensures that the brakes remain balanced.

Replace the brake linings when they are

  • worn to 1/16 inch (1.6 mm) or less remaining thickness

  • contaminated with grease or oil

  • abnormally scored or gouged

    Note: Hairline heat cracks are normal in the brake linings and should not cause concern.

Yearly Brake Cleaning and Inspection

Inspect and service your electric brakes once a year or more often with heavy use or declining performance

  • Change magnets and shoes when they become worn or scored.

  • Clean the backing plate, magnet arm, magnet, and brake shoes with an automotive brake cleaner.

  • Ensure that all parts removed are replaced in the same brake and drum assembly that they were removed from.

  • Inspect the magnet arm for any loose or worn parts.

  • Check the shoe return springs, the hold down springs, and the adjuster springs for stretch or deformation and replace them if required.

    Caution

    Brake dust can be hazardous to your health if inhaled, take precautions when servicing brakes:

    • Do not create or breathe dust.

    • Do not machine, file, or grind the brake linings.

    • Do not use compressed air or dry brushing for cleaning.

Brake Lubrication

Before reassembling the electric brakes, apply a light film of anti seize compound, or grease such as “Lubriplate,” on the:

  • brake anchor pin

  • actuating arm bushing and pin

  • areas on the backing plate that are in contact with the brake shoes and magnet lever arm

  • actuating block on the actuating arm

Important: Do not allow grease to contact the brake linings, drums, or magnets.

Inspecting the Magnets

The brakes’ electromagnets are designed to provide the proper input force and friction.

Inspect the magnets regularly, and replace if they become unevenly worn. Use a tool with a straight edge to check wear.

Even if the wear is normal, you should replace the magnets if any part of the magnet coil is visible through the friction material on the magnet face. Replace the magnets in pairs (both sides of an axle).

When replacing the magnets, also resurface the drum armature surface.

Storage

Before storing the machine for the season:

  1. Thoroughly clean the machine. Remove parts if necessary.

  2. Remove the handheld remote. Also, remove the batteries from the Remote.

  3. Check all fasteners and tighten, if necessary.

  4. Grease all fittings and pivot points. Wipe off any excess lubricant.

  5. Lightly sand any painted areas that are scratched, chipped, or rusted, and apply touch up paint.

  6. Store the machine indoors, if possible.

Troubleshooting

Checking Fault Codes (EH Models Only)

If the Diagnostic LED indicates that there is a system fault (refer to Diagnostic LED Function (EH Models)), check the fault codes to determine what is wrong with the machine.

Entering Diagnostic Mode and Checking the Codes

  1. Push the E-STOP button down to turn off the power.

  2. Pull the tethered cap off of the two diagnostic, shunt connectors (Figure 64, A).

  3. Connect the diagnostic, shunt connectors together (Figure 64, B).

    g028876

    Figure 64

  4. Pull the E-STOP up to turn on the power.

  5. Count the number of flashes to determine the fault code, then consult the following table:

    Note: If there are multiple faults, both faults will flash, then a long pause, then the flash sequences will repeat.

    CodeLED Flash PatternBehaviorDetails

    BASE is bad; contact your Toro Distributor.
    12Blink once, pause, blink twice, long pause, then repeatVersion incompatibility of the BASE and/or HHWrong software (install the correct software from TORODIAG); contact your Toro Distributor.
    13Blink once, pause, blink 3 times, long pause, then repeatWrong HH—not implemented on RevAWrong product association (i.e. trying to update software on a MH–400 with a ProPass handheld)

Reseting the Fault Code

After solving the problem, reset the fault codes by disconnecting and reconnecting diagnostic connectors. The diagnostic light will flash continuously at 1 Hz (1 flash per second).

Exiting Diagnostic Mode

  1. Push the E-STOP button down to turn off the power; refer to E-Stop button.

  2. Disconnect the diagnostic, shunt connectors.

  3. Push the tethered cap onto the two diagnostic, shunt connectors.

  4. Pull the E-STOP up to turn on the power.
