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.

• Immediately seal off lines and connections with clean plugs or protective caps.

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

• Carefully cover or plug unpacked components if repairs cannot be performed immediately.

• Only install clean components: Remove the replacement parts from their packaging just prior to installing them. Do not use parts that have been stored outside of their original packaging (for example 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.
