Even small pieces of debris can cause faults. Follow the following rules of cleanliness when working on the hydraulic system:
- Hydraulic oil damages paint. Remove any hydraulic fluid that leaks onto painted surfaces immediately.
- To bleed any residual pressure in the system, place a clean cloth around the connection and carefully loosen it. The cloth prevents hydraulic fluid from getting onto any painted parts.
- Before loosening, thoroughly clean the connection points and surrounding areas with engine or brake cleaner, and then allow the cleaned area to dry completely.
- Seal off any open lines and connections immediately with clean plugs, for example, taken from Engine Bung Set :VAS6122 .
- Place the removed parts on a clean surface and cover them. Only use 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 parts that have been stored outside of their packaging (for example, in tool boxes etc.).
- Do not work with compressed air when the system is open. Do not move the vehicle if at all possible.
- Protect any disconnected connectors from dirt and moisture, and only connect them when they are completely dry.
