Clean Working Conditions

Even minor contamination can lead to malfunctions in the fuel injection system. Therefore when working on the fuel supply/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.
• Plug open lines and connections immediately with appropriate 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.).
• When the system is open: Do not work with compressed air. Do not move vehicle unless absolutely necessary.
