Fuel System
Maintenance
DANGER
In certain conditions, fuel is extremely
ammable and highly explosive. A re or
explosion from fuel can burn you and others
and can damage property .
Refer to Fuel Safety ( page 16 ) for a complete
list of fuel related precautions.
W ARNING
Fuel-system components are under high
pressure. The use of improper components
can result in system failure, fuel leakage, and
possible explosion.
Use only approved fuel lines and fuel lters.
Servicing the Electronic
Fuel-Injection System
EFI Machines Only
This machine contains an electronic fuel-injection
system. It controls the fuel ow under dif ferent
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) illuminates. The MIL
is the red light located in the right console panel.
Once the MIL illuminates, make initial troubleshooting
checks; refer to the MIL section under T roubleshooting
( page 63 ) .
If these checks do not correct the problem, further
diagnosis and servicing by an Authorized Service
Dealer is necessary .
Replacing the Fuel Filter
Service Interval : Every 200 hours/Y early (whichever
comes rst) (more often in dirty or
dusty conditions).
The fuel lter is located near the engine on the front
or rear side of the engine.
1. Park the machine on a level surface, move the
speed-control lever to the N EUTRAL position,
disengage the blade-control switch (PT O), and
engage the parking brake.
