Rules for cleanliness

When working on the fuel supply/injection system, carefully follow the “5 rules” below:

• Thoroughly clean all joints and surrounding areas before dismantling.
• Place removed parts on a clean surface and cover them over. Use lint-free cloths only.
• Carefully cover opened components or seal them if repairs cannot be carried out immediately.
• Install clean components only: do not remove replacement parts from packing until immediately before installing. Do not use parts that have been kept unpackaged (for example in toolboxes).
• If system is open, do not work with compressed air. Do not move the vehicle.
