Right Rail Assembly Repair Procedures
2. Reinstall the pinch guard. Be sure to orient the pinch guard with the holes in the keyhole slots at the
bottom of the rail.
3. Drop a length of wire down the inside of the extended upright so that the wire appears at the bottom,
and attach that wire to the holes in the upper hole of the tube of the door opening assembly. Then use
the wire to pull the tube so that it is guided into the extended upright. Ensure that the wire and tube
cannot fall back down the extended upright.
4. Slide the assembly back into the upright, reinstall the screws that secure it to the belt channel and
reinstall the side roller bracket. To make sure it is properly seated in its tracks, move the rail assembly
through its full range of travel to make sure it does not hang-up or bind before reattaching the upright
to the device. Reinstall the 2 pieces of the motor coupler that fit on the shaft at the base of the upright
that mate with the coupler piece on the gearbox shaft.
5. To assist in reattaching the upright to the device, there are four mounting studs on the bracket casting
that mate with four holes in the upright. Place the upright on the studs. Be sure the canopy bracket is in
front of the upright. Be careful not to pinch any wires between the device and the upright.
6. Secure the upright to the device by reinstalling the 2 screws in the holes inside the upright. Pull any
excess wiring slack in the upright channels into the electrical enclosure. Be careful not to drop the
screws into the upright.
7. Push the lift rail down into the upright until the rail locking screws align with the horizontal oblong holes
halfway down the rail. Lock the rail by turning the screws CCW (4 mm hex key) until they lock the inner
rail in place. Install the two flat head screws that attach the canopy bracket to the lift rail.
8. Attach ground wire to rail. Fasten the display module to the upright with the two screws and nut bar
removed earlier.
9. Reinstall the wire cover. Take care to route the wires in the upright channels and not to pinch them with
the cover when securing with the screw.
10. Remove the Display head assembly by following the steps in
11. Raise the elevating base to the highest position.
12. Using the wire that was attached to the tube, position the tube so that the lower hole in the tube lines
up with the small hole in the back of the lift rail. Push a hex key through the smaller hole in the lift rail
into the lower hole in the tube to hold the tube in place. You may want to tape the hex key in place so
that it cannot fall out during assembly. Remove the wire.
13. Reconnect the heater door cable. Push the conical cap back through the hole in the front of the lift rail.
Reconnect the conical cap to the plastic tube by tightening the screw. Do not over-tighten the screw or
you may damage the plastic tube. Reinstall the access hole cover.
14. Secure the steel cable routing tube back in position with its 2 mounting screws.
15. Attach the door cable assembly to the bracket at the bottom upright. Position the top nut and flat
washer so the bottom of the flat washer is in the middle of the threads. Slide the threaded heater door
opening rod through the bracket, then install the flat washer, lock washer, and nut (8 mm wrench).
16. Use a straight blade screwdriver in the slot at the cable rod's end to hold the rod and use the wrench to
tighten the bottom nut.
17. Install the upper end cap.
18. Slide the decorative strip up and install the bottom end cap.
19. Reinstall the right inside cover around the door cable with the 2 nuts and screws removed earlier.
20. Reinstall the heater housing cover and canopy soffit.
21. Release the intermediate rail locks by tightening the rail locking screws so the screw heads disengage
from the horizontal oblong holes in the uprights.
22. Reinstall the lift motor/gear box. In order to get the splines on the motor coupler to line up you may
need to push the lift rail into the upright to rotate the rail side coupler. Then reattach the motor/gear
box to its mounting plate with the 2 screws removed earlier.
