There is no risk of overheating during
long periods of operation. The heating
system is maintenance-free. Contact
your dealer if you have any problems.
STIHL recommends a STIHL servicing
dealer.
If engine is down on power, difficult to
start or runs poorly at idling speed, first
check the spark plug.
Fit a new spark plug after approx. 100
operating hours or earlier if the
electrodes are badly eroded.
Wrong fuel mix (too much engine oil in
the gasoline), a dirty air filter and
unfavorable running conditions (mostly
at part throttle etc.) affect the condition
of the spark plug. These factors cause
deposits to form on the insulator nose
which may result in trouble in operation.
Removing the Spark Plug
N Rotate the screw (1) in the cap (2)
until the screw head projects from it.
