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 carburetor 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 (0,020"). The spark plug
should be replaced after about a month in operation or earlier
if necessary.
Adjustment of the oil pump
Adjustments are made by turning the screw using a
screwdriver or combination spanner.The machine is supplied
from the factory with the screw set to position 2. Turning the
screw clockwise will reduce the oil flow and turning the screw
anti-clockwise will increase the oil flow.
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.
Recommended settings:
Bar 13"-15": Position 1
Bar 15"-18": Position 2
Bar 18"-20": Position 3
These recommendations apply to Husqvarna’s chain oil, for
other chain oils increase the oil flow by one step.
WARNING! The engine must be stopped
when making adjustments.
