The ignition lead should always be removed from the spark 
plug before repair, cleaning or maintenance work.

Refer to the separate engine manual for all engine 
maintenace instructions.

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.

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.

Remove the air filter cover.

Remove the air filter and check that it is undamaged. Replace 
with a new air filter if you believe it to be defective.

Clean the filter by knocking the filter against a flat surface. 
Never use solvents, for example petrol or kerosine, or 
compressed air to clean the filter.

When reassembling, make sure that the filter completely 
seals against the filter holder.

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. The spark plug should be 
checked regularly.

CAUTION! Always use the recommended spark plug type, 
refer to Technical Data. Use of the wrong spark plug can 
damage the piston/cylinder.

The muffler is designed to reduce the noise level and to direct 
the exhaust gases away from the operator. The exhaust 
gases are hot and can contain sparks, which may cause fire 
if directed against dry and combustible material.

Regularly check that the muffler is securely attached to the 
machine.

Never use a machine that has a faulty muffler.
