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

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 screws holding the air filter. Take care when 
lifting out the air filter so that dirt does not fall down into the 
carburettor.

Lift off the cover and remove the air duct.

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

Wash the filter with a liquid cleaning agent and water. After 
cleaning the filter should be oiled using engine oil.

Proceed as follows:

•

Put the filter in a plastic bag and pour in new and clean 
engine oil. 

•

Knead the plastic bag to distribute the oil equally in the 
filter. 

Squeeze excess oil from the filter into the plastic bag.

Fit the filter in the filter cover; make sure the edge of the filter 
comes out to the edge of the cover and forms a protective 
seal.

Replace the air duct and fit the cover.

Secure the air filter on the carburettor with the screws.

Loosen the screw holding the air filter cover and lower the 
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.
