DANGER
◼ Use manual lowering only in emergency situations.
◼ Only trained skilled workers may carry out emergency lowering work
under the supervision of a qualified person.
◼ Only continue to operate the lifting system after the fault has been
rectified and the proper function confirmed by a qualified person.
◼ When lowering, always pay attention to the horizontal position of the
vehicle.
◼ This procedure only applies in the event that the safety interlock of the
defective lifting units can be opened by pulling on the pin.
◼ If the safety interlock can not be opened, the supervisor must be notified.
If necessary, request customer service.
