  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.
• Screw the spark plugs into the engine hand-tight with the special tool 0 496 065 (12 1 230).

  NOTE: TECHNICAL INFORMATION 
  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.
• Tighten the spark plugs with the torque wrench, the special tool 0 495 560 (12 1 220)  and with a pivotable extension.
