Risk of fire! Danger of explosion!

When working on the fuel system, make sure that the workbay is sufficiently ventilated, e.g. using extraction unit.
Tightly seal off open lines and connections; collect any leakage fuel directly at the point of exit.
No fire, sparks, open flames or smoking.

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. The silicone tube is coated with talcum powder to reduce the pulling forces.
