Install spark plugs

NOTE: TECHNICAL INFORMATION
In order to avoid an uncontrolled flashover of ignition sparks, special attention must be paid to the cleanliness of the insulator (ceramic) of the spark plugs.
Do not tap the insulator of the spark plugs with your fingers or label it and make sure it does not come into contact with liquid media, such as fuel or oil.
Always handle spark plugs at the spark plug thread. Guiding in the spark plugs using a clean hose (installation aid 12 1 230) is permitted.

NOTE: The description is provided only at one component. The procedure is the same for all other components.

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.

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.
