21 | Winding Springs |
Tools: Step Ladder, Approved winding bars, 3/8” Wrench |
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.
IMPORTANT: Check the warning tag(s) attached to the spring(s) for the re- quired number of complete turns, to balance your door.
WARNING
Prior to winding or making adjustments to the springs, ensure you’re winding in the proper direction as stated in the Instal- lation Instructions. Otherwise the spring fittings may release from spring if not wound in the proper direction and could result in severe or fatal injury.
Alternately inserting the winding rods into the holes of the springs 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 while tightening 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
