Rules for cleanliness

When working on the exhaust gas turbocharger, pay careful attention to the following rules of cleanliness:

• 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 carried out 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.).
• Existing transport and protective packaging and sealing caps must only be removed immediately prior to installation.
• When repairing remove oil from connections and hose ends.
• When the system is open: Do not work with compressed air if this can be avoided. Do not move the vehicle unless absolutely necessary.
