MAINTENANCE

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.

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:

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.

 

 

 

 

 

Cooling system

To keep the working temperature as low as possible the machine is equipped with a cooling system.

The cooling system consists of:

1Air intake on the starter.

2Air guide plate.

3Fins on the flywheel.

4Cooling fins on the cylinder.

5Cylinder 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.

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.

”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.

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.
