Husqvarna 359 EPA III 用户手册

36 – English

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 grease being squirted into the centre 
of the crankshaft using a grease gun.

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 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.

Recommended settings:

Bar 13"-15": Position 1

Bar 15"-18": Position 2

Bar 18"-20": Position 3

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.

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.

Centrifugal cleaning means the following: All air to the 
carburetor passes through the starter. Dirt and dust is 
pushed 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 
carburetor compartment.
