Traction Control To move forward, move the traction control forward. To move rearward, move the traction control rearward (Figure 5). To turn, rotate the traction control in the desired direction (Figure 5). The farther you move the traction control in any direction, the faster the traction unit will move in that direction.
Parking Brake Lever procedures based on a 100, 200, or 400 hour schedule. These reminders come on starting three To set the parking brake, push the brake lever hours prior to the service interval time and flash forward and to the left and then pull it rearward at regular intervals for six hours.

Note: A fuel stabilizer/conditioner is most effective when mixed with fresh gasoline. To minimize the chance of varnish deposits in the fuel system, use fuel stabilizer at all times. Filling the Fuel Tank 1. Park the traction unit on a level surface, lower the loader arms, and stop the engine.
Important: If the engine is run at high speeds when the hydraulic system is cold (i.e., when the ambient air temperature is near freezing or lower), hydraulic system damage could occur. When starting the engine in cold conditions, allow the engine to run in the middle throttle position for 2 to 5 minutes before moving the throttle to fast (rabbit).

Page 35
7. When the track is off of the tension wheel, remove it from the drive sprocket and road wheels (Figure 39). 8. Beginning at the drive sprocket, coil the new track around the sprocket, ensuring that the lugs on the track fit between the spacers on the sprocket (Figure 39).
16. Torque the nut to 300 ft-lb (407 N⋅m). 17. Turn the tensioning screw counter-clockwise until the distance between the tension nut and the back of the tension tube (Figure 37) is 2-3/4 inches (7 cm). 18. Align the closest notch in the tension screw to the locking bolt hole and secure the screw with the locking bolt and nut.
Adjusting the Traction Control Alignment If the traction control bar does not rest flush and square with the reference bar when in the full backward position, immediately complete the following procedure: 1. Park the traction unit on a flat surface and Figure 45 lower the loader arm.
When the traction unit 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 traction unit. 5. If the left track moves, lengthen or shorten the right traction rod until the track stops moving.
Changing the Hydraulic Fluid Change the hydraulic fluid after every 400 operating hours or yearly. 1. Position the traction unit on a level surface. 2. Open the hood. 3. Install the cylinder lock, stop the engine, and remove the key. 4.
Hydraulic fluid escaping under pressure can penetrate skin and cause injury. Fluid 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. • Keep your body and hands away from pin hole leaks or nozzles that eject high pressure hydraulic fluid.
Cleaning the Chassis Over time, the chassis under the engine collects dirt and debris that must be removed. Using a flashlight, open the hood and inspect the area under the engine on a regular basis. When the debris is 1 to 2 inches deep, complete the following procedure (refer to Figure 51 throughout this procedure): Figure 52...
