◆ Unscrew the drainage screw (1) and at the same
time completely rotate the pump control lever (2)
until the oil drains off, then tighten the screw
again.
◆ Keep the pump lever rotated until all traces of air
bubbles have completely disappeared from the
carburettor supply pipe.
For greater safety we advise using up all
the blended fuel in the tank before refill-
ing with only premium grade petrol (see
“TECHNICAL FEATURES”).
◆ Adjust the motor idling speed, then check that the
end play of the oil pump and the carburettor ca-
bles is the same; if not, regulate the adjusters pro-
vided in order to obtain a clearance of 1 mm.
◆ Check that there are no twist in the petrol hose
and oil hose.
If there are twist then replace the hose.
