Clean Working Conditions

Clean Working Conditions

Even a little contamination can lead to faults. Therefore when working on the fuel supply and injection system, pay careful attention to the following rules of cleanliness:

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

• Seal open lines and connections immediately using suitable protective caps.

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

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

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

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

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