Fuel System
Maintenance

Servicing the Electronic Fuel
Injection System

This machine contains an electronic fuel injection
system. It controls the fuel flow under different
operating conditions.

Checking the Malfunction Indicator
Light

If the malfunction indicator light (MIL) illuminates,
during operation, the electronic control unit (ECU) has
detected a problem or fault in the direct fuel injection
(DFI) system.

Once the MIL illuminates, initial trouble shooting checks
should be made. Refer to Troubleshooting , page 59,
under the MIL section.

If these checks do not correct the problem, further
diagnosis and servicing by an Authorized Service Dealer
is necessary.

Servicing the Fuel Filters

Replacing the Fuel Filter

Service Interval:

Every 400 hours (or yearly, which ever

comes first) (more often in dirty or
dusty conditions).

Ensure that an Authorized Service Dealer replaces the
fuel filter and any components for the fuel system.

Use of improper components can result in
system failure, fuel leakage and possible
explosion.

•

Ensure that an Authorized Service Dealer
replace the fuel filter and any components
for the fuel system.

•

Use only approved fuel lines, hose clamps
and fuel filters for high pressure systems.

Hydraulic tank

Servicing the Fuel Tank

Do not attempt to drain the fuel tank. Ensure that an
Authorized Service Dealer drains the fuel tank and
services any components of the fuel system.
