CHECKING / ADDING FUEL
To add fuel:
1. Remove the fuel cap.
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 recommenda-
tions.
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 radiator shroud and the
other is located on the engine. The water separator
should be drained every 50 hours or whenever water is
visible in the bowl. Replace the 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 drain-
ing.
6. Prime the fuel system to remove any air from the fil-
ter and fuel lines. See Priming the Fuel System on
page 11 for complete instructions.
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.
