Installing High-Pressure Pump

→ 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.

→ Perform leak test.
