with oil.
Setting for increased oil delivery rate
If necessary, the oil flow can be
increased beyond the standard setting.
N Press in end stop (2) using a
suitable tool – end stop is no longer
functional, the oil flow can be
increased further
If the end stop has been pressed in, it
remains in this position.

when the fuel tank is approximately
half empty
NOTICE
If an increased oil flow is no longer
required, reset the adjusting screw to the
