NOTE: TECHNICAL INFORMATION 
Do not drop the spark plug into the spark plug shaft. This can lead to a reduction of the electrode gap and can thus impair smooth running of the engine, especially in idle position.

Only a swiveling extension for the reversible ratchet may be used. Rigid mounting tool and variable plug connections with rigid option may not be used; there is a risk that the insulator breaks.
