WARNING: Do not remove an air spring under any circumstances when there is pressure in the air spring. Do not remove any components
supporting an air spring without either exhausting the air or providing support for the air spring to prevent vehicle damage or personal
injury.
CAUTION: Failure to observe the following instructions can result in a sudden failure of the air spring or suspension system.
^
Any rear spring which is unfolded must be refolded prior to being installed in a vehicle.
^
The air spring refolding procedure should only be used for an air spring which has never supported the vehicle's weight while in the incorrectly
folded position.
^
Improperly folded air springs found on vehicles during pre-delivery inspection or after use must be replaced.
^
Do not attempt to inflate any air spring which has been collapsed while uninflated from the rebound hanging position to the jounce stop.
^
When installing a new air spring, care must be taken not to apply a load to the suspension until the springs have been inflated using the air spring
fill procedure.
^
After inflating an air spring in the hanging position, it must be inspected for correct shape.
CAUTION: Prior to installing an air spring, make sure the air spring is in the correct shape with no folds or creases. If the air spring is not in the
correct shape, carry out air spring refold before installing the air spring. See: Air Spring Refold
