4) Locate the manual override thumbscrew (red) on the top of the descent valve (Applicable to
the power packs with the manual override function).
5) Verbally indicate to all those involved that the lift will now be lowered.
6) Slowly turn the manual override thumbscrew in the counterclockwise direction until the lift
starts to move.
7) Keep a close eye on the movement of the lift and the position of the vehicle; turn the
manual override thumbscrew clockwise if any abnormal movement is detected.
8) Once the lift is fully lowered, turn the override thumbscrew in the clockwise direction until
tight.
9) If a rag was used to bypass the mechanical locks, ensure that the rag is removed after the
lift has been put back into operation.
10) Once power is restored follow the lockout/tag out procedure to return the lift back into
service.
IF THE MECHANICAL LOCKS ARE ENGAGED:
Various methods can be used to raise the lift in order to get sufficient clearance to disengage the
mechanical locks. The safest method would employ temporary electrical power to the lift using a
portable power generator. Any electrical connections should be done by a licensed electrician;
lock out/tag out procedures should also be employed at this time.
This process should only be performed by a trained professional. Contact customer service or a local
service professional for further assistance.
