To check for wear, remove the spark plug connector and screw out the spark plug.
If the electrode is badly worn, the spark plug must be replaced as a matter of course
(for order no. see original spare parts list and accessories).
Otherwise it is sufficient to clean the spark plug with a steel brush and set the electrode
gap to between 0.7 – 0.8 mm. Screw the spark plug (pay attention to sealing ring) into
the engine by hand and tighten using the socket wrench. Press on spark plug
connector. Replace the spark plug annually.
