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.
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.
If engine is down on power, difficult to
start or runs poorly at idling speed, first
check the spark plug.
N
Remove spark plug – see "Starting /
Stopping the Engine".
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 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 approximately
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 the spark plug
boot (1) snugly onto the spark plug
terminal (2).
Do not use a spark plug with a
detachable SAE adapter terminal (3).
Arcing may occur that could ignite
combustible fumes and cause a fire.
This can result in serious injuries or
damage to property.
N
Only use resistor type spark plugs
with solid, non-threaded terminals
Installing the spark plug
N
Screw in spark plug
N
Firmly press the spark plug
connector onto the spark plug.
N
Align the spark plug connector so
that the ignition cable points to the
upper left corner (arrow).
