Vehicle Damage Warnings

Rules for cleanliness

When working on the fuel supply/injection system, pay careful attention to the following "6 rules":
- Thoroughly clean all unions and adjacent areas before disconnecting.
- Place removed parts on a clean surface and cover. Do not use fluffy cloths.
- Carefully cover opened components or seal if repairs cannot be performed immediately.
- Only install clean components: Only unpack replacement parts immediately prior to installation. Do not use parts that have not been stored in their packing (e.g. in tool boxes etc.).
- When the system is open: Do not work with compressed air if this can be avoided. Do not move the vehicle unless absolutely necessary.
- Also ensure that no diesel fuel contacts the coolant hoses. If necessary, hoses must be cleaned immediately. Affected hoses must be replaced.
