Preparation Safety • While operating, always wear substantial footwear and long trousers. Do not operate the equipment when barefoot or wearing open sandals. • Thoroughly inspect the area where the equipment is to be used and remove all objects which may be thrown by the machine. • Warning- Fuel is highly flammable. – Store fuel in containers specifically designed for this purpose. – Refuel outdoors only and do not smoke while refueling. – Add fuel before starting the engine.
• When using any attachments, never direct discharge of material toward bystanders nor allow anyone near the machine while in operation. Some attachments, such as a snowthrower, are capable of amputating hands and feet and throwing objects – stay alert for humps and hollows and other hidden hazards; • Do not operate near drop-offs, ditches, steep banks or water. Tracks dropping over edges can cause roll overs, which may result in serious injury, death or drowning.

Maintenance Recommended Maintenance Schedule(s) Maintenance Service Interval Maintenance Procedure After the first 10 hours • Torque the frame mounting bolts. • Torque wheel lug nuts. Every 50 hours • Lubricate grease fittings • Check the tire pressure. Every 200 hours • Torque wheel lug nuts. If you leave the key in the ignition switch, someone could accidently start the engine and seriously injure you or other bystanders. Remove the key from the ignition before you do any maintenance.
Electrical System Maintenance Important: Whenever working with the electrical system, always disconnect the battery cables, negative (-) cable first, to prevent possible wiring damage from short-outs. Checking the Fuses Refer to the Operator’s Manual supplied with the cab for instructions on fuses. If the machine has any electrical system issues, check the fuses. Grasp each fuse and remove them one at a time, checking to see if any are blown.
Drive System Maintenance Checking the Tire Pressure Service Interval: Every 50 hours Check the tire pressure every 50 hours (Figure 131). Maintain the air pressure in the tires at 35 psi . Uneven tire pressure can cause lose of traction. If a lose of traction occurs, tire pressure may be increased to 50 psi to increase track tension. Check the tires when they are cold to get the most accurate pressure reading. Figure 132 1. Access covers 3.
Storage Note: You may need to move the floor jack to the rear bumper to raise the rear of the machine high enough to install the flat washer and locknut. Machine Note: The front and center wheels can be removed without raising and supporting the rear of the machine. 1. Thoroughly clean the machine and cab, paying special attention to these areas: • PTO shaft assembly • All grease fittings and pivot points • Oil the spline on the PTO output shaft to prevent rusting 2.
