Do not fuel or run the engine unless the spark
arrester is installed.
1. Shut off the engine, wait for all moving parts to stop,
remove the key, and engage the parking brake.
2. Wait for the muffler to cool.
3. If there are any breaks in the screen or welds, replace

loose particles out of the arrester, and clean the screen
with a wire brush (soak in solvent if necessary).
5. Install the arrester on the exhaust outlet.

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 (EFI)
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, initial trouble shooting
checks should be made. Refer to the MIL section under
Troubleshooting (page
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 (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
