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.
