Replace filter canister after every 400 hours of operation.
1. Clean area where filter canister mounts.
2. Remove filter canister and clean mounting surface.
3. Lubricate gasket on filter canister with clean oil.
4. Install filter canister by hand until gasket contacts
mounting surface, then rotate an additional 1/2 turn.
Replacing Fuel Pre Filter
Replace the fuel pre filter (Fig. 45), located between 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 lines are removed (Fig. 45).
2. Loosen the hose clamps at both ends of the filter and
pull fuel lines off filter.
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 in. (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.
