23 | Securing Door For Spring Winding(s) |
Tools: Vice Clamps |
With the door in the fully closed position, place vice clamps onto both vertical tracks just above the third track roller. This is to prevent the garage door from rising while winding springs.
WARNING
Failure to place vice clamps onto vertical track can allow door to raise and cause severe or fatal injury.
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 downward toward the floor, 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
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.
NOTE: An unbalanced door such as this can cause garage door opener operation problems.
