Fuel System
Maintenance
DANGER
Under certain conditions, fuel and fuel vapors
are highly flammable and explosive. A fire or
explosion from fuel can burn you and others
and can cause property damage.
• Fill the fuel tank outdoors, in an open area,
when the engine is off and is cold. Wipe up
any fuel that spills.
• Do not fill the fuel tank completely full. Add
fuel to the fuel tank until the level is 25 mm
(1 inch) below the top of the tank, not the
filler neck. This empty space in the tank
allows the fuel to expand.
• Never smoke when handling fuel, and stay
away from an open flame or where fuel
fumes may be ignited by a spark.
• Store fuel in a clean, safety-approved
container and keep the cap in place.

Draining the Fuel Tank

Service Interval: Every 800 hours
Before storage
Park the machine on a level surface, lower the cutting
units, engage the parking brake, shut off the engine,
and remove the key.
Drain and clean the fuel tank if the fuel system
becomes contaminated or if the machine is to be
stored for an extended period. Use clean fuel to flush
out the tank.
Checking the Fuel Lines
and Connections
Service Interval: Every 400 hours/Yearly (whichever
comes first)

Inspect the fuel lines for deterioration, damage, or
loose connections.

Cleaning the Fuel-Intake
Screen
Park the machine on a level surface, lower the cutting
units, engage the parking brake, shut off the engine,
