Cleaning the air filter
N Undo the fastening screws in the
filter cover
N Remove filter cover
N Remove coarse dirt from inside the
filter cover and around the filter (5)
N Knock out the filter (5) or blow it
clear with compressed air from the
inside outwards
In case of stubborn dirt or stuck filter
fabric:
N Wash the filter in a clean, non-
flammable cleaning liquid (e. g.,
warm soapy water) and dry it.
Always replace a damaged filter.
N If the engine is down on power,
difficult to start or runs poorly at idle
speed, first check the spark plug.
N Fit a new spark plug after about 100
operating hours – or sooner if the
electrodes are badly eroded. Install
only suppressed spark plugs of the
type approved by STIHL – see
"Specifications".
Removing the Spark Plug
N Rotate the screw (1) in the cap (2)
until the screw head projects from it.
N Lift the front of the cap (2) and push
it to the rear to disengage.
N Leave the cap to one side.
N Pull off the spark plug boot (3).
N Unscrew the spark plug.
Checking the spark plug
N Clean dirty spark plug.
N Check electrode gap (A) and
readjust if necessary – see
"Specifications".
N Rectify the problems which have
caused fouling of the spark plug.
Possible causes are:
– Too much oil in fuel mix.
– Dirty air filter.
– Unfavorable running conditions.
If the spark plug comes with a
detachable adapter nut (1), screw the
adapter onto the thread and tighten it
down firmly to reduce the risk of arcing
and fire.
