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.

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

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.

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.
