Clean Working Conditions

Clean Working Conditions

Even a little contamination can lead to faults. Observe the following guidelines for cleanliness when working on the fuel system, injection system and turbocharger:

• Before loosening, connections and surrounding areas must be cleaned thoroughly with engine or brake cleaner, and then cleaned area must be dried completely.

• Immediately seal off lines and connections with clean plugs or caps.

• Place parts that have been removed on a clean surface and cover them. Use lint-free cloths.

• Carefully cover over opened components or seal, if repairs are not performed immediately.

• Only install clean components: Only unpack replacement parts immediately prior to installation. Do not use parts that have been stored unpacked (for example in tool boxes etc.).

• When the system is open: Do not work with compressed air. Do not move vehicle unless absolutely necessary.

• Make sure no fuel gets onto the fuel hoses. If necessary, wipe off the fuel hoses immediately. Replace any corroded fuel hoses.

• Protect disconnected electrical connectors from dirt and moisture and only connect if dry.
