Fuel System
Maintenance
DANGER
Under certain conditions, diesel fuel and fuel
vapors are highly flammable and explosive. A
fire or an explosion from fuel can burn you
and others and can cause property damage.
• Use a funnel and 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 6
to 13 mm (1/4 to 1/2 inch) below the bottom
of 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.

Servicing the Fuel Tank

Service Interval: Every 2 years—Drain and clean the
fuel tank.
Drain and clean the tank if the fuel system becomes
contaminated or if the machine will be stored for an
extended period of time. Use clean fuel to flush out
the tank.
Inspecting the Fuel Lines
and Connections
Service Interval: Every 400 hours/Yearly (whichever
comes first)
Inspect the fuel lines and connections for deterioration,
damage, or loose connections.
