MAINTENANCE
Air filter
The air filter must be regularly cleaned to remove dust and dirt in order to avoid:
SCarburetor malfunctions S Starting problems
S Loss of engine power
S Unnecessary wear to engine parts S Excessive fuel consumption
Clean the filter every 25 hours, or more regularly if conditions are exceptionally dusty.
Cleaning the air filter
Remove the air filter cover and take out the filter. Wash it clean in warm, soapy water. Rinse thoroughly. Ensure that the filter is dry 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.
