7. MAINTENANCE
■ SPARK PLUG
Do not touch the spark plug with
bare hands immediately after
stopping the engine. The spark
plug is still so hot and might
cause burns.
Take out the spark plug, check the
electrodes, and if contaminated,
clean them with a wire brush, etc.
every 25 hours of use.
When mounting the spark plug,
screw the plug in with your fingers,
and then tighten it with the plug
wrench supplied as a standard
accessory.
The spark gap should be adjusted to
0.6 to 0.7 mm.
[Tightening torque]
9.8 to 11.8 N-m (100 to 120 kgf-cm)
Designated spark plug

If you use the plug wrench to start
tightening the spark plug, the thread
might become damaged.
■ AIR COOLING VENT
Do not put any waste into the
intake air-cooling vent while the
machine is in operation. It might
touch the rotating part, causing
danger.
Check the intake air-cooling vent and
the cooling fin of the cylinder, and
remove any dirt attached thereto
every 25 hours of use.
If any waste or dirt is jammed
between the intake air-cooling vent
and the cylinder fin, the engine might
overheat, causing trouble.
(1) Cylinder fin
(2) Intake air-cooling vent
