MAINTENANCE

Cooling system

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.

Spark plug

The spark plug condition is influenced by:

Incorrect carburetor adjustment.

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 0,6-0,7 mm. The spark plug should 
be replaced after about a month in operation or earlier if 
necessary.

CAUTION! 

 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.

Two-piece shaft 

The drive shaft end in the lower shaft should be lubricated 
with grease every 30 hours. There is a risk that the drive shaft 
ends (splined coupling) on models with two-piece shafts will 
seize if they are not lubricated regularly.

Air filter

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.

Cleaning the air filter

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.
