Servicing the Fuel System

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 inch (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 Tank
Drain and clean the fuel tank every 800 hours.
Also, drain and clean the tank if 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.
Fuel Lines and Connections
Check the fuel lines and connections every
400 hours or yearly, whichever comes first.
Inspect them for deterioration, damage, or loose
connections.
Water Separator
Drain water or other contaminants from the water
separator (Figure 51) daily.
1. Place a clean container under the fuel filter.
2. Loosen the drain plug on the bottom of the
filter canister (Figure 51). Tighten the plug
after draining.

1. Water Separator
Replace filter canister after every 400 hours of
operation.
A. Clean the area where the filter canister
mounts.
B. Remove the filter canister and clean the
mounting surface.
C. Lubricate the gasket on the filter canister
with clean oil.
D. Install the filter canister by hand until the
gasket contacts the mounting surface; then
rotate it an additional 1/2 turn.
Replacing the Fuel Pre-Filter
Replace the fuel pre-filter (Figure 52), located
between fuel the tank and fuel pump, after every
400 operating hours or yearly, whichever occurs
first.
1. Clamp both fuel lines that connect to the fuel
filter so that fuel cannot drain when the lines
are removed.
2. Loosen the hose clamps at both ends of the
filter and pull the fuel lines off of the filter.
