Husqvarna 252RX ユーザーズマニュアル

30 – 

English

If the mesh is 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 mesh 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

Fins on the flywheel.

3

Cooling fins on the cylinder.

4

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 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. 

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.

Remove the air filter cover and remove both filters, A and B. 
A is an air filter and B is a pre-filter. Both must be washed in 
warm soapy water and dried. Filter A must then be soaked in 
oil, see instructions under the heading Oiling the air filter.
