Catalytic Converter*
Checking the Spark Plug
Units with a catalytic converter* may
only be operated with unleaded
gasoline and STIHL two cycle engine
oil or equivalent quality two cycle engine
oils in a mix ratio of 50:1 (see chapter
“Fuel”).
If engine is down on power, difficult to
start or runs poorly at idling speed, first
check the spark plug.
:
Remove spark plug – see "Starting /
Stopping the Engine".
:
:
Clean dirty spark plug.
The catalylic converter in the muffler
reduces noxious emissions in the
exhaust gas.
Check electrode gap (A) and
readjust if necessary – see
"Specifications".
Correct adjustment of the carburetor (if
adjustable) and observance of the
specified mix ratio of gasoline and two
cycle engine oil are essential to
:
Use only resistor type spark plugs
of the approved range.
Rectify problems which have caused
fouling of spark plug:
minimize harmful exhaust emissions
and ensure a long catalyst service life.
:
:
:
Too much oil in fuel mix.
Dirty air filter.
Unfavorable running conditions,
e.g. operating at part load.
Wrong fuel mix (too much engine oil in
the gasoline), a dirty air filter and
Fit a new spark plug after approx.
100 operating hours
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.
or earlier if the electrodes are badly
eroded.
