before taking any further action. If the spark plug is dirty,
clean it and check that the electrode gap is 0.5 mm. The
spark plug should be replaced after about a month in
operation or earlier if necessary.
Note! Always use the recommended spark plug type! Use
of the wrong spark plug can damage the piston/cylinder.
Check that the spark plug is fitted with a suppressor.

Lubricating the bar tip sprocket

Lubricate the bar tip sprocket each time you refuel. Use
the special grease gun and a good quality bearing grease.

Needle bearing lubrication

The clutch drum has a needle bearing on the output shaft.
This needle bearing must be lubricated regularly (once a
week).
When lubricating, remove the clutch cover by loosening
the two bar nuts. Lay the saw on its side with the clutch
drum upwards.
Lubrication involves engine oil dripping into the centre of
the clutch drum as it rotates.
