Guidelines For Clean Working Conditions

Even Very Small Particles of Dirt Can Cause a Fault. 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.
• Immediately seal off lines and connections with clean plugs or 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 the repair will not be done 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 (for example in tool boxes etc.).
• If the system is open: do not work with compressed air. If possible do not move vehicle.
• Protect any disconnected connectors from dirt and moisture and connect them only when they are completely dry.
