Fuel System
Maintenance
DANGER
Under certain conditions, diesel fuel and fuel
vapors are highly flammable and explosive. A fire
or explosion from fuel can burn you and others and
can cause property damage.
• Use a funnel and fill the tank outdoors, in an
open area, when the engine is off and is cold.
Wipe up any fuel that spills.
• Do not fill the fuel tank completely full. Add fuel
to the fuel tank until the level is 25 mm (1 inch)
below the bottom of the filler neck. This empty
space in the tank allows the fuel to expand.
• Never smoke when handling fuel, and stay away
from an open flame or where fuel fumes may be
ignited by a spark.
• Store fuel in a clean, safety-approved fuel
container and keep the cap in place.
Checking the Fuel Line and
Connections
Service Interval: After the first 50 hours
Every 400 hours/Yearly (whichever comes first)
Inspect the lines and connections for deterioration, damage,
or loose connections.

Bleeding the Fuel System

1. Park the machine on a level surface.
2. Ensure that the fuel tank is at least half full.
3. Open the vent plug on the fuel/water separator (Figure
44)

4. Turn the key in the ignition switch to the On position.
Note: The electric fuel pump will begin forcing air out
around the air bleed screw.
5. Leave key in the On position until a solid stream of fuel
flows out around the screw.
6. Tighten screw and turn the key to the Off position.
7. Open the air bleed screw on the fuel injection pump
(Figure 45).

8. Turn key in ignition switch to the On position.
Note: Electric fuel pump will begin operation, thereby
forcing air out around air bleed screw on fuel injection
pump.
9. Leave the key in the On position until a solid stream
of fuel flows out around the screw.
10. Tighten the screw and turn the key to the Off position.
Note: Normally, the engine should start after you bleed the
fuel system. However, if the engine does not start, there may
be air trapped between the injection pump and the injectors;
refer to (page ).
