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.
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.

•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.
