Removing Fuel Injector

→ Ventilate the work area well.

→ Never ingest or inhale.

→ Read specific information on the Hazard Sheet.

→ Do not smoke, eat or drink in the work area.

→ Avoid contact with hot parts or sources of ignition.

→ Use suction to remove ignitable vapours.

→ Attach warning sign in a clearly visible position.

→ Thoroughly clean connection points and adjacent areas before loosening them. If the engine is very dirty, wash it before starting disassembly work.

→ Lay removed parts on a clean surface and cover them. Do not use fibre-shedding cloths.

→ Carefully cover components or seal them if repair work will not be carried out immediately. Place rubber caps on connections. Seal intake openings with film or adhesive tape.

→ Only install clean parts. Do not take spare parts out of the packaging until just before installation.

→ Never use compressed air when the system is open. Do not move the vehicle.

Information 

Absorb any escaping fuel using a suitable binding material or a cloth. 

Cloths which have absorbed fuel must be disposed of according to the applicable national laws. 

The fuel system must be depressurized before starting work on it. 

Only work on the fuel system in well-ventilated rooms. 

Any seals which have been removed must always be replaced. 

Do not use any sealant containing silicone or silicone spray when the injection system is open. Traces of silicone drawn in by the engine are not combusted and damage the oxygen sensors.
