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. One at a time, remove each fuse from the fuse block and check the fuse to determine if it is open (blown). If you need to replace a fuse, always use the same type and amperage rated fuse as the fuse you are replacing, otherwise you may damage the electrical system.

Note: If a fuse blows frequently, you may have a short in the electrical system and should have it serviced by a qualified service technician.

Important: Check the air pressure in the tires before the machine is operated.

Check that the air pressure tires is 240 kPa (35 psi); refer to Figure 131.

Note: Uneven air pressure in the tires can cause loss of traction. If the machine losses traction, increase air pressure in the tire to 344 kPa (50 psi) to increase track tension.
