possible. Blow it out with low-pressure compressed air.
■
Clean the appliance regularly with a damp cloth and a mild detergent.
Make sure that no water can penetrate into the interior of the appliance.
Cleaning the air filter
Contaminated air filters reduce the engine output due to low air supply to
the carburettor.
Regular inspection is essential. The air filter must be inspected regularly and
cleaned if necessary.
The air filter must be checked more frequently if the air is dusty.

Electrode gap = 0.6 mm (distance between the electrodes between
which the ignition spark is generated). Check the spark plug for contam-
ination after the first 10 hours of operation and clean it with a copper
wire brush if required.
Afterwards, service the spark plug after every 50 hours of operation.
Maintaining the carburettor settings
