Husqvarna 336 Manuel D’Utilisation

34 – 

English

The spark plug condition is influenced by:

•

Incorrect carburetor adjustment.

•

An incorrect fuel mixture (too much or incorrect type of 
oil).

•

A dirty air filter.

These factors cause deposits on the spark plug electrodes, 
which may result in operating problems and starting 
difficulties.

If the machine is low on power, difficult to start or runs poorly 
at idle speed: always check the spark plug first before taking 
any further action. If the spark plug is dirty, clean it and check 
that the electrode gap is 0.5 mm (0,020"). The spark plug 
should be replaced after about a month in operation or earlier 
if necessary.

Note! Always use the recommended spark plug type! Use of 
the wrong spark plug can damage the piston/cylinder. Check 
that the spark plug is fitted with a suppressor.

Lubricate the bar tip sprocket each time you refuel. Use the 
special grease gun and a good quality bearing grease.

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. 
CAUTION! Max. 1 1/2 turns.

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.
