Guidelines For Clean Working Conditions

• Thoroughly clean connecting points and their surrounding areas before loosening.
• Place the removed parts on a clean surface and cover them so that are not contaminated. Use foil and paper. Only use lint-free cloths.
• Only install clean parts: remove the replacement parts from their packaging just before installing them.
• Only use greases and sealants that are designated with part numbers.
• Carefully cover or seal opened components if the repair is not performed immediately.

Air Suspension

• Make sure that no dirt enters the pressure air system.
• Clean the area before removing connecting pieces, air lines or pressurized air system components.
• Seal off any open compressed air lines and connections in the pressure system immediately with plugs or cover them.
