Regulated air should only be used for temporary raising or lowering of the trailer for obstacle
clearance. It is not intended for routine operation.
Note:
The ride height setting may not produce an immediate change due to the dead bands of the
Height Control Valve. Engage the selected Height Control Valve setting by dumping and
re-inflating the suspension.
