Husqvarna 233RJ Manuel D’Utilisation

196 – English

To keep the working temperature as low as possible the 
machine is equipped with a cooling system.

The cooling system consists of:

1

Cooling fins on the cylinder.

2

Air intake.

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. 

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.

Fuel filter

When the engine runs short of fuel supply, check the fuel 
cap and the fuel filter for blockage.

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.
