Clean Working Conditions

Even a little contamination can lead to faults. When working on the fuel supply and fuel injection system, observe the following guidelines for a clean working environment:

• 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 the removed parts on a clean surface and cover them. Only use lint-free cloths!
• Carefully cover or seal opened components if repairs are not performed immediately.
• Install only clean parts: remove the replacement parts from their packaging just before installing them. Do not use parts that have been stored outside of their original packaging (e.g. in tool boxes etc.).
• When the system is open: do not work with compressed air. Do not move vehicle unless absolutely necessary.
• Protect the disconnected connectors from dirt and moisture and only connect when they are dry.
