23 | Chalking Torsion Spring(s) | |
Tools Required: Step Ladder, Chalk | ||
|
Draw a chalk line horizontally along the center of the torsion spring coil(s). As the torsion spring is wound, the chalk line will create a spiral. This spiral can be used to count and determine the number of turns that are applied on the torsion spring.

NOTE: Check the following before attempting to wind torsion spring(s): a. Counterbalance lift cables are secured at bottom corner brackets. b. Counterbalance lift cables are routed unobstructed to cable drums.
c. Counterbalance lift cables are correctly installed and wound onto cable lift drums. d. Counterbalance lift cables are taut and have equal tension on both sides.
e. Cable lift drums are against end bearing brackets and set screws are tight. f. Torsion spring or springs are installed correctly.
g. Review the label attached to the spring warning tag, to determine number of spring turns required.
NOTE: Door MUST be closed and locked when winding or making any adjustments to the torsion spring(s).
WarningARNING
Failure to ensure door is in a closed position and to place vice clamp onto vertical track can allow door to raise and cause severe or fatal injury.
WarningARNING
Use only specified winding bars, as stated in Step Securing Door for Spring Winding. DO NOT SUBSTITUTE with screwdriv- ers, pipe, etc. Other tools may fail or release from the spring cone and cause serious personal injury.
WarningARNING
Prior to winding or making adjustments to the springs, en- sure you’re winding in the proper direction as stated in the Installation Instructions. Otherwise the spring fittings may release from spring if not wound in the proper direction and could result in severe or fatal injury.
Position a ladder slightly to the side of the spring so that the winding cone is easily acces- sible, and so your body is not directly in line with the winding bars.
Check the label attached to the spring warning tag for the required number of complete turns to balance your door.

Alternately inserting the winding rods into the holes of the spring winding cone, rotate the winding cone upward toward the ceiling, 1/4 turn at a time, until the required number of complete turns for your door height is achieved. As the last 1/8 to 1/4 turn is achieved, securely hold the winding rod and carefully stretch the torsion spring 1/8” - 1/4”. Next while still securely holding the winding rod, tighten both set screws in the winding cone to
Carefully remove winding rod from winding cone. Repeat for the opposite spring. While holding the door down to prevent it from raising unexpectedly in the event the spring(s) were

Adjustments to the number of turns stated may be necessary. If door rises off floor under spring tension alone, reduce spring tension until door rests on the floor. If the door is hard to rise or drifts down on its own, add spring tension.
Torsion spring(s) should be wound in the direction the end coil points.
