Fuel System

Fuel Tank
Drain and clean fuel tank every 800 hours of operation or
yearly, whichever comes first. Also, drain and clean tank if
fuel system becomes contaminated or if machine is to be
stored for an extended period. Use clean fuel to flush out
the tank.
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 1/4 to 1/2 in.
(6 to 13 mm) 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.
Fuel Lines and Connections
Check lines and connections every 400 hours or yearly,
whichever comes first. Inspect for deterioration, damage, or
loose connections.

separator (Fig. 32) daily.
