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 fuel 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 6 to 13 mm
(1/4 to 1/2 inches) 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 container
and keep the cap in place.

Bleeding the Fuel System

You must bleed the fuel system before starting the engine if
any of the following situations have occurred:
•
Initial start up of a new machine.
•
Engine has ceased running due to lack of fuel.
•
Maintenance has been performed upon fuel system
components (e.g., filter replaced).

1. Fuel injection pump bleed screw
4. Turn the key in the ignition switch to the On position.
Note: The electric fuel pump will begin operation,
thereby forcing air out around the air bleed screw.
Leave the key in the On position until a solid stream
of fuel flows out around the screw.
5. Tighten the screw and turn the key to the Off position.
Note: Normally, the engine should start after the above
bleeding procedures are followed. However, if engine does
not start, air may be trapped between injection pump and
injectors; contact your Authorized Service Dealer.
Checking the Fuel Lines and
Connections
Service Interval: Every 400 hours/Yearly (whichever
comes first)—Check the fuel lines and
connections for deterioration, damage,
or loose connections.
Inspect the fuel lines and connections for deterioration,
damage, or loose connections. Tighten any loose connections
and contact your Authorized Service Dealer for assistance
in fixing damaged fuel lines.
