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.
• Install only clean parts: remove the replacement parts from their packaging just before installing them. 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.
