3. Maintenance of the spark plug
Use only an original high-quality spark plug.
To ensure smooth operation of the engine, the spark plug must be free of sediments and the electrode
intervals must be adjusted correctly.
1. Remove cover of the spark plug.
2. Remove sediments off the spark plug.
3. Remove spark plug with a spark plug
spanner.
4. Check spark plug visually. Dispose of plug in case of
damage or splittered places on the insulator.
5. Measure electrode intervals with an adequate gauge. The
interval should measure 0.6-0.7 mm.
6. Ensure that the sealing ring of the spark plug is in good
condition. Screw in spark plug by hand in order to avoid
tearing of the thread.
7. After screwing the spark plug in, tighten the plug with a
spark plug spanner to compress the sealing ring.
8. Replace plug back tightly onto the spark plug.
9. Replace cover of spark plug.
