3.1
Rules for cleanliness when working on
auxiliary/supplementary heater and fuel
system
When working on the fuel supply and injection system, pay careful
attention to the following "rules":
♦ Thoroughly clean all unions and adjacent areas before dis‐
connecting.
♦ Place removed parts on a clean surface and cover them over.
Use lint-free cloths only.
♦ Carefully cover opened components or seal them if repairs
cannot be carried out immediately.
♦ Install only clean parts; do not remove new parts from pack‐
aging until immediately before installing. Do not use parts that
have been kept unpackaged (for example in toolboxes).
♦ When the system is open: Do not work with compressed air.
♦ Do not move the vehicle.
♦ Immediately seal open lines and unions with clean plugs, for
example from engine bung set - VAS 6122- .
♦ Protect disconnected electrical connectors from dirt and water,
and reconnect them only when dry.
