Cleaning the air filter
Dismantle the air filter cover (B) and remove the air filter. Wash in clean, warm soapy water. Ensure that the filter is dry before refitting.
An air filter used for a long period of time can never be cleaned completely. Therefore it is necessary to replace the filter from time to time with a new filter. A damaged air filter must always be replaced.
Spark plug
The condition of the spark plug is affected by:
•An incorrect carburettor setting.
•An incorrect fuel mixture (too much or faulty oil).
•A dirty air filter.
These factors cause deposits on the spark plug electrode that may result in malfunction or starting difficulties.

If the machine is low on power, difficult to start or runs poorly while idling always check the spark plug first before taking other action.
The spark plug is accessed from under the cylinder cover, which is removed by loosening the four bolts (A).
If the spark plug is dirty, clean it and at the same time check that the electrode gap is 0.5 mm. The spark plug should be changed after about one month of operation or earlier if necessary.
NOTE! Always use the recommended type of spark plug. An incorrect spark plug can damage the cylinder/piston.
