Tightly seal off open lines and connections; collect any leakage fuel directly at the point of exit.
No fire, sparks, open flames or smoking.

CAUTION: On releasing high pressure line, fuel may emerge at high speed .
Injury hazard!

Wear suitable personal protective equipment.
Before performing any installation work, allow cooling system to cool down to less than 40°C.
Note warnings on cylinder head cover.

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: TECHNICAL INFORMATION
