N Check electrode gap (A) and
readjust if necessary – see
"Specifications".
N Use only resistor type spark plugs of
the approved range.
Rectify problems which have caused
fouling of spark plug:
N Too much oil in fuel mix.
N Dirty air filter.
N Unfavorable running conditions,
e.g. operating at part load.
Fit a new spark plug after approx. 100
operating hours or earlier if the
electrodes are badly eroded.
WARNING
To reduce the risk of fire and burn injury,
use only spark plugs authorized by
STIHL. Always press spark plug boot (2)
snugly onto spark plug terminal (1) of the
proper size. (Note: If terminal has
detachable SAE adapter nut, it must be
attached.) A loose connection between
spark plug boot and ignition wire
connector in the boot may create arcing
that could ignite combustible fumes and
cause a fire.
Installing the Spark Plug
N Screw the spark plug into the
cylinder.
N Press the spark plug boot firmly
onto the spark plug.
N Fit the cap (1) on the shroud from
the rear and push the lug (2) into the
opening (3) in the shroud at the
same time.
N Swing the cap forwards onto the
shroud, insert and tighten down the
screw (4) firmly.
If engine running behavior is still
unsatisfactory after servicing the air filter
and adjusting the throttle cable, the
cause may be the muffler.
Have the muffler checked by a servicing
dealer for contamination
(carbonization).
STIHL recommends that you have
servicing and repair work carried out
exclusively by an authorized STIHL
servicing dealer.
