Components/air tubes
IMPORTANT:
Maintain the highest possible standards of cleanliness in the area of the air tube connections when removing and installing components and air tubes. Even the tiniest dirt particles on the pipe connections or damage to the air tubes can result in leaks in the air spring system!
Do not kink, twist or crush the air tubes!
Air tube connections must be sealed off with adhesive tape immediately after they have been removed. The adhesive tape may only be removed shortly before the connection is reinstalled.
