Checking the Spark Plug
N Clean dirty spark plug.
N Check electrode gap (A) and
readjust if necessary – see
"Specifications."
N Use only resistor type spark plugs of
the approved range.
Rectify problems that have caused
fouling of spark plug:
– too much oil in fuel mix,
– dirty air filter,
– unfavorable running conditions, e.g.
operating at part load.
WARNING
To reduce the risk of fire and burn injury,
use only spark plugs authorized by
STIHL. Always press spark plug boot (1)
snugly onto spark plug terminal (2) of the
proper size. (Note: If terminal has
detachable SAE adapter nut, it must be
securely 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 boot firmly onto the spark
plug.
To help prolong the wear life of the
starter rope, observe the following
points:
N Pull the starter rope only in the
direction specified.
N Do not pull the rope over the edge of
the guide bushing.
N Do not pull out the rope more than
specified.
N Do not allow the starter grip to snap
back, guide it back into the housing
slowly – see chapter on "Starting /
Stopping the Engine."
Have a damaged starter rope replaced
by your dealer before it breaks
completely. STIHL recommends that
you have servicing and repair work
carried out exclusively by an authorized
STIHL servicing dealer.
