mm). The spark plug should be replaced after about a
month in operation or earlier if necessary.

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 40 hours, or more regularly if
conditions are exceptionally dusty.
Avoid contact with hot surfaces on muffler, cylinder etc.
Contact can result in burns to the skin.
Cleaning the air filter
Dismantle the outer cover with the help of the four
fasteners holding the outer cover.
Loosen the two fasteners holding the air filter cowling and
remove the filter. Wash the filter clean in warm, soapy
water.
The air filter is fitted in the air filter cowling.
Ensure that the filter is soaked in oil 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.
