NOTE: RISK OF DAMAGE
Contaminant or foreign body.
Contamination can result in malfunctions, loss of function or leaks .

Adhere to the utmost cleanliness.
Protect components from contamination e.g. by covering.
Close off line connections with seal plugs.

NOTE: RISK OF DAMAGE
Damage to the ignition coil.
The silicone hose of the ignition coil must not be contaminated by fuel as this can lead to failure of the ignition coil.

When working on the fuel system, cover the ignition coils with suitable materials and remove where required.
Do not oil or grease the silicone tube of the spark plug socket. Do not use any protection or maintenance products (e.g. silicone spray, rubber care products, rust remover, etc.).

NOTE: RISK OF DAMAGE
Damage to the injector tips and Teflon ring.
Improper handling of the injector tips and Teflon ring can lead to malfunctioning of the injector.

Avoid mechanical contact with injector tip.
When exchanging Teflon ring, hands and work surface must be clean and free of oil. Do not use any lubricating agents.
Do not use fingernails to slide Teflon ring on.

NOTE: RISK OF DAMAGE
Damage to injectors.
Excessive force may damage the injector and this means having to replace the injector.

Twist the injectors with a torsional movement of maximum 13 Nm.

NOTE: TECHNICAL INFORMATION
When assembling, it is essential to observe Figure.
Non-observance of these requirements may result in leaks and damage.

NOTE: TECHNICAL INFORMATION
