Installing all spark plugs
NOTE:
The description is provided only at one component. The procedure is the same for all other components.
- Insert spark plug (1) into special tool 0 496 065 (12 1 230)
. 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). NOTE: TECHNICAL INFORMATION
Exclusively swiveling extensions may be used for the reversible ratchet. 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.
