Refuelling The Excavator; Bleeding The Fuel System - Kubota U17-3a Operating Instructions Manual

Refuelling the excavator

When refuelling the excavator, smoking, an open flame, or other sources of ignition are not al-
lowed. The danger zone has to be clearly marked with signs. In the danger zone, there has to be
a fire extinguisher.
Spilled fuel must be bound immediately with an oil binding agent. The contaminated oil binding
agent must be disposed of in accordance with the applicable environmental regulations.
If no pumping station is available, the diesel fuel may only be stored in approved canisters.
Refuel the excavator in time so that the fuel tank is not running empty. Air in the fuel system can
damage the fuel injection pump.

Stop the engine.

Open the fuel filler flap (page 75).

Open the filler cap (1).

Fill in diesel fuel.
The fuel display (2) is positioned next to the filler
plug. When the fuel tank is almost full (only 2 L
missing), the display indicator starts moving to-
wards "F" (full). Check the display to avoid overfill-
ing.

Clean the air tank ventilation (3) inside the filler cap.
Mud at the ventilation causes a depression inside the fuel reservoir.

Attach the filler cap and lock the fuel filler flap.

Bleeding the fuel system

If the excavator fuel tank was run empty or the water separator was cleaned, the fuel system
must be bled.

To bleed the fuel system, move the starter switch to the RUN position. The electrical fuel pump will bleed
the fuel system automatically within approx. 60 s.

If the bleeding was insufficient, the engine will stop again. In this case repeat the procedure.
