Fuel System
Maintenance
WARNING
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 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
LED status light illuminates. The MIL is the red light
located on the right side of the hour meter.
Once the light illuminates, make initial troubleshooting
checks; refer to the LED status light 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/Yearly (whichever
comes first)
The fuel filter is located near the engine on the front
or rear side of the engine.
1.
Park the machine on a level surface, disengage
the blade-control switch, and engage the parking
brake.
2.
Shut off the engine, remove the key, and wait
for all moving parts to stop before leaving the
operating position.
3.
Wait for the machine to cool down.
4.
Close the fuel-shutoff valve under the seat
(Figure

2. Hose clamp
5.
Squeeze the ends of the hose clamps together
and slide them away from the filter
6.
Remove the filter from the fuel lines.
7.
Install a new filter and move the hose clamps
close to the filter
8.
Open the fuel-shutoff valve.
Important:
Install 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 can 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
serviceable.
Important:
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 and
services any components of the fuel system.
