The Lift Cable Tension Adjuster shown in Figure 3A allows for the door, the door opening and
the tracks to be a small amount out of plumb, level and square. However, if they are out too
much, one of the lift cables may fall off the cable drum as the bottom of the door opens to the
curve. If this happens, first check to make sure the horizontal tracks are parallel and square
with the door. The cable drums must be securely fastened to the torsion tube. WARNING! If
the problem is caused by loose cable drum set screws, which allowed cable drum slippage,
the torsion springs must have their tension released before a satisfactory cable drum
adjustment can be made. Start over again at STEP 22. Also check the door, the door
opening and the tracks for plumb, level, and square.
WARNING! EXTREME CAUTION MUST BE EXERCISED WHILE
ADJUSTING THE TORSION SPRINGS!
STEP 27
With the door fully open and working free, make final adjustments to the horizontal tracks.
Leave about 1/2" (13) space between the side of the door and the horizontal track, then
fasten the punched angle brace with 3/8 X 1” short neck carriage bolts and 3/8" lock nuts.
The punched angle track hanger should be vertical.
(See Figure 20)
WARNING! Be sure the door is in the down position if the punched angle
Track hanger needs to be unfastened and moved to another position.
STEP 28
Note: Doors over 14’ (5270) high and any extra heavy door that causes the horizontal
tracks to deflect more than 1/2“ (13) in 10’ (3050) should also be center hung and
braced with punched angle to support the weight.
