Regular Maintenance
WARNING
Diesel fuel is highly flammable and must be
handled with care. Never fill the tank when the
engine is still hot from recent operation. Do
not allow open flame, smoking or matches in
the area. Avoid over-filling and wipe up any
spills.
Do not drain or replace fuel filter when engine
is hot, as spilled fuel may ignite. Make sure the
filter drain valve is fully closed before returning
the unit to service.
Do not use Kerosene in place of diesel
fuel or mix with diesel fuel. Kerosene will
damage the engine.
Consult the engine manufacturer’s manual
for specific fuel recommendations.
WARNING
Fuel leaked or spilled onto hot surfaces or
electrical components can cause a fire. To
help prevent possible injury, turn the ignition
switch off when changing fuel filters or water
separator elements. Clean up fuel spills
immediately.

This unit is equipped with two fuel filters. One is
a water separator (A, Figure 14) and the other is a
fuel filter (C). Both filters are located in the engine
compartment on the right side of the engine. The
water separator should be drained every 25 hours
or whenever water is visible in the bowl. Replace
both fuel filters every 500 hours of operation or as
required.

Checking / Adding Fuel
To add fuel:
1. Remove the fuel cap (A, Figure 13).
2. Fill the tank to the bottom of the fill tube. This will
leave room in the tank for fuel expansion.

for specific fuel recommendations.
3. Install and hand tighten the fuel cap.
4. Repeat same process for opposite tank.
To Replace the Fuel Filter:
NOTE: Fuel filter is replaced as an assembly only.
The filter element is not replaceable separately.
1. Turn the engine off, set the parking brake, remove
the ignition key, and wait for all moving parts to
stop.
2. Allow the engine and surrounding areas to cool to
room temperature.
3. Close both fuel tank shut off valves (See Figure 2
for location).
4. Open the hood to gain access to the fuel filter.
The fuel filter is located in the engine compartment
on the right side of the engine.
5. Place an absorbent cloth below the filter to catch
any spilled fuel.
