MAINTENANCE
Needle bearing lubrication
Cooling system
The clutch drum has a needle bearing on the output shaft.
This needle bearing must be lubricated regularly (once a
week).
To keep the working temperature as low as possible the
machine is equipped with a cooling system.
The cooling system consists of:
When lubricating, remove the clutch cover by loosening
the two bar nuts. Lay the saw on its side with the clutch
drum upwards.

Air intake on the starter.
Air guide plate.
Fins on the flywheel.
Lubrication involves engine oil dripping into the centre of
the clutch drum as it rotates.
Cooling fins on the cylinder.
Cylinder cover (directs cold air over the cylinder).
Adjustment of the oil pump
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.
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
Note! The cooling system on a chain saw with catalytic
converter must be cleaned daily. This is particularly
important on chain saws with catalytic converters,
because the higher exhaust temperature requires
efficient cooling of the engine and the catalytic converter
unit.

turn open. Turning the screw clockwise will reduce the
oil flow and turning the screw anti-clockwise will increase
the oil flow.
”Air Injection” centrifugal
cleaning
Centrifugal cleaning means the following: All air to the
carburettor passes through the starter. Dirt and dust is
centrifuged out by the cooling fan.
Recommended settings:
Bar -15":
1 turn from the closed position.
2 turns from the closed position.
3 turns from the closed position.
4 turns from the closed position.
Bar 15" -18":
Bar 18" -24":
Bar 24" -:
IMPORTANT! In order to maintain operation of the
centrifugal cleaning system it must be regularly
maintained. Clean the air intake to the starter, the fins on
the flywheel, the space around the flywheel, inlet pipe and
carburettor compartment.
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
