Fuel System
Maintenance
WARNING
Fuel system components are under high pressure.
The use of improper components can result in
system failure, gasoline leakage and possible
explosion.
Use only approved fuel lines and fuel filters.
Servicing the Electronic
Fuel-Injection System
This machine contains an electronic fuel-injection system. It
controls the fuel flow under different operating conditions.
The electronic control unit (ECU) continuously monitors the
operation of the EFI system.
If a problem or fault within the system is detected, the
malfunction indicator light (MIL) is illuminated. The MIL is
the red light located in the right console panel.
Once the MIL illuminates, perform initial trouble shooting
checks. Refer to the MIL section under
(page
65).
If these checks do not correct the problem, further diagnosis
and servicing by an Authorized Service Dealer is necessary.
Replacing the Low-Pressure
Fuel Filter
Service Interval: Every 200 hours/Yearly (whichever comes
first) (more often in dirty or dusty
conditions).
The fuel filter is located near the engine on the front or rear
side of the engine.
1. Disengage the PTO, move the motion-control levers to
the neutral-locked position, and set the parking brake.
2. Stop the engine, remove the key, and wait for all moving
parts to stop before leaving the operating position.
3. Allow the machine to cool down.
4. Stop the engine, remove the key, and wait for all moving
parts to stop before leaving the operating position.
5. Close the fuel shutoff valve under the seat
Troubleshooting
Note: It is important to reinstall the fuel line hoses and
secure with plastic ties the same as they were originally
installed at the factory to keep the fuel line away from
components that could cause fuel line damage.
Servicing the High-Pressure
Fuel Filter
Do not attempt to service the high pressure fuel filter. The
high pressure filter is integrated within the fuel pump module.
The fuel filter and other components inside the fuel pump
module are not servicable. Do not attempt to open the fuel
pump module.
Ensure that an Authorized Service Dealer replaces the fuel
pump module with the high pressure fuel filter.
Servicing the Fuel Tank
Do not attempt to drain the fuel tank. Ensure that an
Authorized Service Dealer drains the fuel tank.
