If your lift is in a raised position and you lose power it
is important to know how to lower the lift manually.
Make sure nothing is under the lift and all
unauthorized personnel are away from the lift area.
1.
Place a hydraulic jack and pipe under one of the
arm carriages. Jack should be rated to lift the capacity
of the vehicle.
2.
Raise lift off of the locking latch. You should only
have to raise lift approximately 1/6" to disengage the
lock.
3.
Remove access panel from the master control
panel. As you are facing the master control panel look
slightly down and to the left and you will see the air
latch valve, Fig. 8.
4.
Depress the button on the top of the air valve, Fig.
8. At this time you should hear the air leave the lift.
Do not use a sharp object to depress the button.
5.
Slowly lower hydraulic jack and pipe out from
under the arm carriage. The lift is now being held up
by hydraulics at this point.
6.
Remove cap from lowering valve and press to
lower lift, Fig. 8. The lift will lower at a slow speed.
Replace cap on lowering valve after lift has been
lowered.
7.
If your facility lost power your lift will operate
when you regain power.
8.
If your facility power was not lost have a certified
electrican check wiring to lift or call an authorized
Rotary repair person.
