Servicing the Fuel System

Note: Refer to Fill the Fuel Tank, page 13, for 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 25 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 after every 800 hours
operation or yearly, whichever comes first. Also, drain
and clean the tank if the fuel system becomes
contaminated or if the machine will be stored for an
extended period. Use clean diesel 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 for
deterioration, damage or loose connections.
Water Separator
Drain water or other contaminants from the water
separator (Fig. 25) daily.
1. Place a clean container under the water separator
(the water separator is mounted to the inside of
the frame, next to the left side of the engine).
2. Loosen the drain plug on the bottom of the filter
canister. Tighten the plug after draining.

Replace the filter canister after every 400 hours of
operation.
1. Clean the area where the filter canister mounts.
2. Remove the filter canister and clean the
mounting surface.
3. Lubricate the gasket on the filter canister with
clean oil.
4. Install the filter canister by hand until the gasket
contacts the mounting surface, then rotate an
additional 1 ⁄ turn.

Replacing the Fuel Pre Filter
Replace the fuel pre filter (Fig. 26), 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 fuel
filter so fuel cannot drain when you remove the
lines.
2. Loosen the hose clamps at both ends of the filter
and pull the fuel lines off the filter.
