Bleeding Air from the Fuel
Injectors
Note: This procedure should be used only if the fuel system
has been purged of air through normal priming procedures
and the engine will not start; refer to Bleeding the Fuel
System.

Cleaning the Fuel Tank
Service Interval: Every 2 years
Drain and clean fuel tank every 2 years. Also, remove and
clean the in-line strainers after draining the tank. Use clean
diesel fuel to flush out the tank.
Important: Drain and clean the tank if the fuel system
becomes contaminated or if the machine is to be stored
for an extended period.
Fuel Lines and Connections
Service Interval: Every 400 hours
Check the fuel lines and connections every 400 hours or
yearly, whichever comes first. Inspect them for deterioration,
damage, chaffing, or loose connections.

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
If the machine stops or has other electrical system issues,
check the fuses. Grasp each fuse in turn and remove them
one at a time, checking to see if any are blown. If you need
to replace a fuse, always use the same type and amperage
rated fuse as the one you are replacing, otherwise you could
damage the electrical system (refer to the decal next to the
fuses for a diagram of each fuse and its amperage).
The traction unit fuses are located under the seat
