Safety • Improper use or maintenance by the operator or owner can result in injury. To reduce the potential for injury, comply with these safety instructions and always pay attention to the safety alert symbol , which means: Caution, Warning, or Danger—personal safety instruction. Failure to comply with the instruction may result in personal injury or death. – Never refuel or drain the machine indoors.
Maintenance and Storage Failure to maintain adequate distance from trees, walls, and other barriers may result in injury as the machine backs up during operation if the operator is not attentive to the surroundings. Only operate the unit in areas where there is sufficient clearance for the operator to safely maneuver the product. • Disengage the hydraulics, lower the grinder, stop the engine, and remove the key. Wait for all movement to stop before adjusting, cleaning, or repairing.
– Battery acid is poisonous and can cause burns. Avoid contact with skin, eyes, and clothing. Protect your face, eyes, and clothing when working with a battery. – Battery gases can explode. Keep cigarettes, sparks and flames away from the battery. • Keep your body and hands away from pin hole leaks or nozzles that eject high pressure hydraulic fluid. Use cardboard or paper to find hydraulic leaks; never use your hands.

3. Clean around the fuel tank cap and remove it (Figure 17). 4. Remove the dipstick and wipe the end clean (Figure 18). 5. Slide the dipstick fully into the dipstick tube without threading it into the filler neck (Figure 18). 6. Pull the dipstick out and look at the end. The oil should be between the Add and Full marks (Figure 18). 7. If the oil is below the Add mark, add 10w30 engine oil to the filler hole, checking the level frequently with the dipstick, until the oil level reaches the Full mark. 8.
Important: Do not engage the starter for more than 10 seconds at a time. If the engine fails to start, allow a 30 second cool-down period between attempts. Failure to follow these instructions can burn out the starter motor. 4. Gradually move the choke lever to the Off position (Figure 21). If the engine stalls or hesitates, engage the choke again until the engine warms up. 5. Move the throttle lever to the desired setting (Figure 21).

Replacing the Fuel Filter Service Interval: Every 200 hours Servicing the Battery Never install a dirty filter if it is removed from the fuel line. Service Interval: Every 25 hours—Check the battery electrolyte level. Note: Note how the fuel filter is installed in order to install the new filter correctly. Always keep the battery clean and fully charged. Use a paper towel to clean the battery case.
5. Remove the hold down plate, j-bolts, and locknuts securing the battery (Figure 40) and remove the battery. WARNING Incorrect battery cable routing could damage the machine and cables causing sparks. Sparks can cause the battery gasses to explode, resulting in personal injury. Installing the Battery 1. Place the battery onto the machine (Figure 40). 2. Secure the battery with the hold down plate, j-bolts, and locknuts.
1. Remove the battery from the machine; refer to Removing the Battery. Important: Never fill the battery with distilled water while the battery is installed in the machine. Electrolyte could be spilled on other parts and cause corrosion. 2. Clean the top of the battery with a paper towel. 3. Remove the vent caps from the battery (Figure 41). 4. Slowly pour distilled water into each battery cell until the electrolyte level is up to the Upper line (Figure 41) on the battery case. Figure 42 /A N : 3.

Starting at the bottom of the front road wheel, install the track around the wheel by rotating the track rearward while pushing the lugs into the wheel. 4. Back out the tensioning bolt and jam nut (Figure 46). 12. If you removed the front, outside road wheel, install it at this time using the bolt and gasket removed previously.
5. Place the greased road wheel cap over the bolt head (Figure 49). Belt Maintenance 6. Secure the road wheel cap with the snap ring (Figure 49). Replacing the Pump Drive Belt 7. Repeat steps 2 through 6 for all 12 road wheels. If the pump drive belt begins to squeal or is cracked, worn, or frayed, replace it. Contact you Authorized Service Dealer for a replacement belt. 8. Install the tracks; refer to Replacing the Tracks (page 29). 1. Raise the grinder. 2.
Controls System Maintenance 5. Adjust the traction control so that it rests flush against the reference bar when it is pulled straight back (Figure 52 and Figure 53). The factory adjusts the controls before shipping the machine. However, after many hours of use, you may need to adjust the traction control alignment, the neutral position of the traction control, and the tracking of the traction control in the full forward position.
4. If the machine veers to the right, loosen the left jam nut and adjust the tracking set screw on the front of the traction control (Figure 55). WARNING When the machine is running, you could be caught and injured in moving parts or burned on hot surfaces. Stay away from pinch points, moving parts, and hot surfaces when adjusting the running machine. F. Have a helper hold the traction control tight to the reference bar in reverse. G.
Hydraulic System Maintenance 8. Pinch the hose clamp and slide the clamp and hose off of the fitting on the hydraulic tank, allowing the hydraulic fluid to drain from the hose and tank into the pan. Replacing the Hydraulic Filter Service Interval: Every 200 hours 1. Position machine on a level surface. 2. Lower the grinder. 3. Stop the engine, remove the key, and wait for all moving parts to stop before leaving the operating position. 4. Remove the top cover.
Checking the Hydraulic Lines Grinder Maintenance Service Interval: Every 100 hours—Check the hydraulic lines for leaks, loose fittings, kinked lines, loose mounting supports, wear, weather, and chemical deterioration and repair if necessary. Replacing the Teeth Service Interval: Before each use or daily—Check the condition of the teeth and rotate or replace any that are worn or damaged. Every 1,500 hours/Every 2 years (whichever comes first)—Replace all moving hydraulic hoses.
Cleaning Storage 1. Lower the grinder. Removing Debris from the Machine 2. Stop the engine, remove the key, and wait for all moving parts to stop before leaving the operating position. Important: Operating the engine with blocked screens, dirty or plugged cooling fins, and/or cooling shrouds removed, will result in engine damage from overheating. 3. Remove dirt and grime from the external parts of the entire machine, especially the engine.
12. Charge the battery; refer to Servicing the Battery (page 26). 13. Check and adjust the track tension; refer to Checking and Adjusting the Track Tension (page 29). 14.
