MAINTENANCE
36 – English
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). CAUTION! Use only high quality bearing grease or
engine oil. See instructions under the heading Cutting
equipment.
Adjustment of the oil pump
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
1 turn open. Turning the screw clockwise will reduce the
oil flow and turning the screw anti-clockwise will increase
the oil flow.
Recommended settings:
These recommendations apply to Husqvarna’s chain oil,
for other chain oils increase the oil flow by one step.
Cooling system
To keep the working temperature as low as possible the
machine is equipped with a cooling system.
The cooling system consists of:
1 Air intake on the starter.
2 Air guide plate.
3 Fins on the flywheel.
4 Cooling fins on the cylinder.
5 Cylinder cover (directs cold air over the cylinder).
Clean the cooling system with a brush once a week, more
often in demanding conditions. A dirty or blocked cooling
system results in the machine overheating which causes
damage to the piston and cylinder.
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.
