Guidelines For Clean Working Conditions

Even small pieces of debris can cause faults. For this reason follow the rules of cleanliness when working:

• Thoroughly clean the connection locations/maintenance openings and the area around them prior to loosening/opening.
• Immediately seal off any open lines and connections with clean plugs taken from the Engine Bung Set:VAS6122  , for example.
• Place removed parts on a clean surface and cover them with lint-free cloths.
• Carefully cover or seal opened components if repairs are not performed immediately.
• Only install clean parts: remove the replacement parts from their packaging just before installing them. Do not use any parts that have been kept out of packaging (for example, in a toolbox).
• Do not work with compressed air when the system is open.
• Protect any disconnected connectors from dirt and moisture, and only connect them when they are completely dry.
