Fuel System
Maintenance
DANGER
Under certain conditions, diesel 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.
• 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 in) 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.

Draining the Fuel Tank

Service Interval: Every 800 hours—Drain and clean the fuel
tank.
Before storage
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 (Or yearly, whichever
comes first).
Check the fuel lines and connections for deterioration,
damage, or loose connections.

Cleaning the Fuel Pick-up
Tube Screen
The fuel pick-up tube, located inside the fuel tank, is equipped
with a screen to help prevent debris from entering the fuel
system. Remove the fuel pick-up tube and clean the screen
as required.

Bleeding the Fuel System
