  NOTE: TECHNICAL INFORMATION 
  Do not drop spark plug into 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 hand-tight into the engine using special tool 0 496 065 (12 1 230).
