MAINTENANCE
Spark plug
The spark plug condition is influenced by:
S Incorrect carburetor adjustment.
S An incorrect fuel mixture (too much or in-
correct type of oil).
S Poor quality gasoline and/or oil
S A dirty air filter .
These factors cause deposits on the spark
plug electrodes, which may result in operat-
ing problems and starting difficulties.
If the machine is low on power, difficult to
start or runs poorly at idle speed: always
check the spark plug first before taking
any further action. If the spark plug is dirty ,
clean it and check that the electrode gap is
0,6 mm. The spark plug should be replaced
after about a month in operation or earlier if
necessary.
0,6 mm
CAUTION! Always use the recommended
spark plug type! Use of the wrong spark
plug can damage the piston/cylinder.
