Fuel System
Maintenance
Note: Refer to Adding Fuel for proper fuel
recommendations.
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
to the bottom of the filler neck.
• 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 Water
Separator
Drain water or other contaminants from water
separator (Figure 45) daily. Replace filter canister
after every 400 hours of operation.
1. Place a clean container under the fuel filter.
2. Loosen the drain plug on the bottom of the
filter canister.

3. Clean the area where the filter canister mounts.
4. Remove the filter canister and clean the
mounting surface.
5. Lubricate the gasket on the filter canister with
clean oil.
6. Install the filter canister by hand until the
gasket contacts mounting surface, then rotate
it an additional 1/2 turn.
7. Tighten the drain plug on the bottom of the
filter canister.
Cleaning the Fuel Tank
Drain and clean fuel tank every 2 years. Also, drain
and clean the tank if the fuel system becomes
contaminated or if the machine is to be stored for
an extended period. Use clean diesel fuel to flush
out the tank.
Replacing the Fuel Pre-Filter
Replace the fuel pre-filter (Figure 46), located
between the fuel tank and fuel pump after every
400 operating hours or yearly, whichever occurs
first.
1. Clamp both fuel lines that connect to the
pre-filter so fuel cannot drain when the lines
are removed (Figure 46).
