Important!
Observe country-specific safety regulations.
Ensure adequate ventilation in the place of work!
Connect the exhaust and extraction systems to the exhaust
tailpipe.
The electric fuel pump must not operate without fuel! After
completing repairs but before starting the engine for the first
time, fill the fuel tank with min. 5 l fuel through the fuel filler
pipe.
Do not damage non-return flap when pulling out extraction
hose.
Drawing off fuel:
Start engine and allow to run.
Important!
The electric fuel pump runs.
In this way, the fuel is repumped through the suction jet pump
and the tank expansion line from the left to the right side of
the fuel tank.
Once fuel has been drawn off through the fuel filler pipe, there
are still residual amounts in the fuel tank, in the fuel filter and
in the fuel pump surge chamber.
Note:
Fuel can be drawn out of the left and right sides of the tank
through the filler neck, leaving only a small residual amount.
This residual amount in the fuel tank is drawn off after removal of
the sensors for the fuel gauge (right/left).
