WARNING

Hot components/surfaces.
Risk of burns!
• Allow the engine to cool down to below 50 °C before beginning work.
• Wear suitable protective equipment/thermal gloves.
• Avoid unprotected contact with hot surfaces.

WARNING

Compressed air gun ejects a jet of pressurized air.
Risk of injury to eyes and damage to hearing, risk of rupturing internal organs!
• Never direct air jet at people.
• Always wear safety goggles/face mask and ear defenders.

Installing spark plug connector

1.

If necessary, remove the ignition line's lower
sealing ring and replace with a new sealing
ring.

2.

Remove any dust and impurities from the ig-
nition line connector's Teflon body - on the
outside and inside on the spark plug side.

3.

Check the spark plug isolator sealing ring for
damage. If damaged, install a new spark plug
isolator sealing ring (→ Page 174).

4.

Insert the ignition line connector (5) into the
spark plug duct, press down the ignition line
flange (6) against the spring force and screw
into the straight union until they abut the
bolts (4) on both sides. The item number on
the flange is in the 6 o'clock position.

5.

Tighten the bolts (4) of the ignition line
flange (6). Check for correct alignment of the
ignition line flange (6) while doing this. The
bolt slots of the flange (6) abut the threads of
the bolts (4) on both sides.

6.

Fasten the ring eyelet of the ignition line (3) to the ignition coil (1) with the bolt and spring washer.
