6. Install the filter canister by hand until the gasket
contacts mounting surface, then rotate it an additional
1/2 turn.
7. Tighten the drain plug on the bottom of the filter
canister.
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.
Bleeding the Fuel System
1. Park the machine on a level surface. Ensure that the
fuel tank is at least half full.
2. Unlatch and raise the hood.
3. Place a rag under the air bleed screw on the fuel
injection pump and open it (Figure 47).

4. Turn the key in the ignition switch to the On position.
The electric fuel pump will begin operation, thereby
forcing air out around the air bleed screw.
CAUTION
The engine may start during this procedure.
Moving fans and belts in a running engine can
severely injure you or bystanders.
Keep hands, fingers, loose clothing/jewelry,
and hair away from the engine fan and belt
during this procedure.
5. Leave the key in the On position until a solid stream
of fuel flows out around the screw.
6. Tighten the screw and turn key to the Off position.
Note: Normally, the engine should start after above
bleeding procedures are followed. However, if engine
does not start, air may be trapped between injection
pump and injectors; refer to Bleeding Air From the
Injectors.
Bleeding Air From the Injectors
Note: This procedure should be used only if the fuel system
has been purged of air through normal priming procedures
and engine will not start; refer to Bleeding the Fuel System.
1. Place a rag under the pipe connection coming from
the injection pump to the No. 1 injector nozzle as
illustrated in Figure 48.
