Emergency Operation
If the lift becomes inoperative in the raised position, it is best to wait until the electrical power is
restored before lowering the lift. However, if it’s critical to safety that the lift be lowered, the following
steps should be taken.
DO NOT LOOSEN OR REMOVE HYDRAULIC CONNECTIONS OR FITTINGS
UNDER PRESSURE. SERIOUS INJURY OR DEATH COULD OCCUR.
NOTE: Safely performing this process requires 3 people. All personnel should stay clear of the
path of the lift. All tools and other non-secured items should be removed from the surface of
the runways.
1) Survey the area surrounding the lift; remove any items and personnel from area before
proceeding with this procedure.
2) Perform the appropriate lockout/tag out procedure on the electrical energy.
3) Add additional chocks to the vehicle to secure it from movement in the forward and rear
direction.
4) Use a second person standing at a safe distance away from the lift to keep watch on the area,
lift, vehicle and other personnel throughout the process. This person should signal the person
performing the procedure to stop if necessary.
5) Use a caution tape or similar to barrier the area around the lift to avoid personnel from
accidently entering the area while this process is being performed.
6) Do not proceed with this procedure if you are unfamiliar with the lift or its function.
IF THE MECHANICAL LOCKS ARE NOT ENGAGED
:
1)
If there is air pressure in the pneumatic system
; have another person press and hold
the mechanical safety release button to disengage the mechanical locks. Confirm that both
mechanical locks have been disengaged and will allow the lift to lower.
If there is no air pressure in the pneumatic system
; use a rag to raise the upper
mechanical locks to sufficiently clear the lower locks on both sides.
2) Remove the 6 screws retaining the rear cover of the control console.
3) Locate the descent valve on the hydraulic power unit, see
Figure 48
