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.
• Remove the air filter after taking off the air filter cover.
When refitting make sure that the air filter seals tightly
against the filter holder. Clean the filter by brushing or
shaking it.
The filter can be cleaned more thoroughly by washing it in
water and detergent.
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.
