Refuelling the excavator
When refuelling the excavator, smoking, an open flame, or other sources of ignition are not al-
lowed. The danger zone must be marked with signs. A fire extinguisher must be kept at hand in
the danger zone.
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 side cover (page 83).
•
Remove the filler cap (1) by swivelling it anticlockwise.
•
Fill diesel fuel up to the base of the filler tube.
•
Refit the filler cap and close the side cover.
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.
