2. 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.

For an exploded view of the spring tube assembly, refer to section 8.13.
1. Elevate the elevating base to the upper limit of travel.
2. Elevate the canopy to the service position, about halfway up so that the black oxide shipping screw is
centered in the horizontal slot, which is about midway up on the outside of the dovetail rail.
3. Turn off the device and unplug it from the wall.
4. Slide up the decorative strip in the dovetail rail slot to expose lower end cap screw. (A piece of adhesive
tape on the decorative strip can help to move it.)
5. Remove the lower end cap.
6. Remove the hole plug from the back of East lift rail. (Refer to
Cable".)
7. Rotate the spring tube assembly until the setscrew hole and lower securing hole are visible from the
access hole in the back of the inner rail. Insert a 2 mm hex wrench through the small hole in the back of
the inner rail through the spring tube and back into the rail to temporarily secure the spring tube
assembly to the inner rail.
8. Unscrew the setscrew in the door cable conical cap until it is possible to separate the door cable cap
from the spring tube. Do not remove the setscrew.
9. Secure a length of string to the cross-hole in the spring tube. The string should be long enough to allow
the spring tube to be removed from the bottom of the rail assembly. Firmly secure the other end of the
string. This string will be used to lift the new spring tube assembly into place.
