Husqvarna 33RJ Manuel D’Utilisation

24 – English

frequently blocked, this can be a sign that the performance 
of the catalytic converter is impaired. Contact your dealer to 
inspect the muffler. A blocked screen will cause the machine 
to overheat and result in damage to the cylinder and piston.

CAUTION!  Never use a machine with a defective muffler.

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

Cooling fins on the cylinder.

3

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.

The bevel gear is filled with the right quantity of grease at the 
factory. However, before using the machine you should 
check that the bevel gear is filled three-quarters full with 
grease. Use HUSQVARNA special grease.

The grease in the bevel gear does not normally need to be 
changed except if repairs are carried out.

The air filter must be regularly cleaned to remove dust and 
dirt in order to avoid:

•

Carburettor malfunctions

•

Starting problems

•

Loss of engine power

•

Unnecessary wear to engine parts

•

Excessive fuel consumption.

Clean the filter every 25 hours, or more regularly if conditions 
are exceptionally dusty.

Remove the air filter cover and take out the filter. Wash it 
clean in warm, soapy water. Ensure that the filter is dry 
before refitting it. 

An air filter that has been in use for a long time cannot be 
cleaned completely. The filter must therefore be replaced 
with a new one at regular intervals. A damaged air filter 
must always be replaced.

If the machine is used in dusty conditions the air filter should 
be soaked in oil. See instructions under the heading Oiling 
the air filter.
