MAINTENANCE
Spark plug
Needle bearing lubrication
The spark plug condition is influenced by:
The clutch drum has a needle bearing on the output shaft.
This needle bearing must be lubricated regularly (once a
week).
•
•
Incorrect carburettor adjustment.
An incorrect fuel mixture (too much or incorrect type of
oil).
When lubricating, remove the clutch cover by loosening
the two bar nuts. Lay the saw on its side with the clutch
drum upwards.
•
A dirty air filter.
These factors cause deposits on the spark plug
electrodes, which may result in operating problems and
starting difficulties.
Lubrication involves engine oil dripping into the centre of
the clutch drum as it rotates.
If the machine is low on power, difficult to start or runs
poorly at idle speed: always check the spark plug first
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.
Adjustment of the oil pump
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.
The oil pump is adjustable. Adjustments are made by
turning the screw using a screwdriver or combination
spanner. The machine is supplied from the factory set to
Lubricating the bar tip sprocket

turn open. Turning the screw clockwise will reduce the
oil flow and turning the screw anti-clockwise will increase
the oil flow.
Lubricate the bar tip sprocket each time you refuel. Use
the special grease gun and a good quality bearing grease.
Recommended settings:
Bar -15":
1 turn from the closed position.
Bar 15" -18": 2 turns from the closed position.
Bar 18" -24": 3 turns from the closed position.
Bar 24" -:
4 turns from the closed position.
These recommendations apply to Husqvarna’s chain oil,
for other chain oils increase the oil flow by one step.
WARNING! The engine must not be
running when making adjustments.
