Oil particles on the spark plug can occur if an incorrect
fuel mixture or too much oil is used. A dirty air filter can
also cause oil particles on the spark plug. Small particles
on the spark plug electrodes can cause problems to
start and operate the product. Always examine the spark
plug if the product is low on power, if it does not start
easily or if it runs unsatisfactorily at idle speed.
1. Make sure that the spark plug cap and ignition are
not damaged to prevent the risk of electrical shock .
2. Clean the spark plug if it is dirty.
3. Do a check that the electrode gap is 0.5 mm. If it is
necessary, replace the spark plug.
To do a general inspection
• Make sure that the nuts and screws on the product
are tightened.
