To check for wear, remove the spark plug connector and unscrew the spark plug. If the
electrode is badly worn the spark plug must be replaced as a matter of course. (Order
no. see original spare parts list and accessories).
Otherwise it is sufficient to clean the spark plug and set the electrode gap to 0.7 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.
