Regular Maintenance
Checking / Adding Fuel
To add fuel:
1. Remove the fuel cap (A, Figure 12).
2. Fill the tank to the bottom of the fill tube. This
will leave room in the tank for fuel expansion.
Refer to your engine manual for specific fuel
recommendations.
3. Install and hand tighten the fuel cap.
4. Repeat same process for opposite tank.
NOTE: The fuel tanks are tied together through a
“tee” in the supply lines. By filling only one tank, the
level will balance between the two tanks, effectively
having 1/2 tank of fuel for each side.
Fuel Filter
This unit is equipped with two fuel filters. One is a
water separator/filter mounted to the frame, under
the seat and the other is located on 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.
To drain the fuel filter:
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. Place a container under the fuel filter tube and
turn the drain valve (B, Figure 13) approximately 1
turn.
4. Allow the filter to drain until all water and debris
have drained out.
5. Turn the drain valve to close it when finished
draining..
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. 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.
The water separator is under suction
during normal engine operation. Ensure
the drain valve is tightened securely to
help prevent air from entering the fuel
system.
