Lift Motor Replacement
As lift is disassembled, keep all parts in order for replacement on the lift.
1. Disconnect power to lift.
2. Remove the closure panel frame.
3. Remove the projector from the lift.
4. Use Duct Tape and tape the wire rope/cable onto the drum to prevent it
from loosening. Slack will let the cable “jump” over and need to be
spooled back onto the drum.
5. Secure the lower frame of the lift with straps/rope – preventing gravity
from letting the frame drop.
6. If the lift is in the retracted position, removal of the scissor sets can gain
better access to the motor assembly – it’s your choice to remove. Remove
the top and bottom scissor nuts – slide the scissor set to the rear of the lift
and remove.

shaft.
