Husqvarna Comprehensive Guide to Chainsaw Needle Bearing Grease Maintenance

MAINTENANCE

Muffler

The muffler is designed to reduce the noise level and to direct the exhaust gases away from the operator. The exhaust gases are hot and can contain sparks, which may cause fire if directed against dry and combustible material.

Some mufflers are equipped with a special spark arrestor mesh. If your machine has this type of muffler, you should clean the mesh at least once a week. This is best done with a wire brush.

CAUTION! The mesh must be replaced if it is damaged. If the mesh is blocked the machine will overheat and this will cause damage to the cylinder and piston. Never use a machine with a muffler that is in poor condition.

Needle bearing lubrication

The clutch drum is fitted with one of the following drive sprockets:

•A Spur sprocket (the chain sprocket is welded on the drum)

•B Rim sprocket (replaceable)

Both versions have a needle bearing on the drive shaft, which has to be greased regularly (once a week).

CAUTION! Use a high-quality bearing grease or engine oil.

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.

WARNING! The engine must not be running

!when making adjustments.

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.

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.
