DANGER

Live components, flash-over.

Risk of serious injury - danger to life!

• During operation, do not touch ignition cable except with insulated glove (at least class 4)!

WARNING

Component is hot.

Risk of burning!

• Wear protective gloves.

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

Clean and dry the mating surfaces on spark

plug (1), sealing ring (2) and cylinder head.

Fit new sealing ring (2) on spark plug (1)

with the flat side facing the isolator.

Check condition of spark plug connector

and ignition cable, replace parts if dam-

aged.

Apply thin coat of assembly compound to

spark plug.
