Balancing Door
Remove locking pliers. Lift door and check its balance. Adjustments to the required number
of spring turns stated may be necessary. If door rises off floor more than 2 ft. under spring
tension alone, reduce spring tension. If the door is hard to rise or drifts down on its own, add
spring tension. A poorly balanced door can cause garage door operator problems.
To adjust spring tension, fully close door. Apply locking pliers to track above third track roller.
Place locking pliers on torsion shaft, as shown in Step Attaching Counterbalance Lift Cables.
Insert a winding rod into the winding cone. Push upward on the winding rod slightly while
carefully loosening the set screws in the winding cone.
IMPORTANT: BE PREPARED TO SUPPORT THE FULL FORCE OF THE TORSION SPRING ONCE
THE SET SCREWS ARE LOOSE.
Carefully adjust spring tension 1/4 turn. Retighten both set screws to 14-15 ft. lbs. of torque
in the winding cone and repeat for the other side. Recheck door balance and re-adjust spring
tension if needed.
IMPORTANT: DO NOT ADJUST MORE THAN 1 TURN FROM THE RECOMMENDED NUMBER
OF TURNS.
If the door still does not operate easily, lower the door into the closed position, unwind
spring(s) completely, and recheck the following items:
1.) Is the door level?
2.) Are the torsion shaft and flag angles / angle mount level and plumb?
3.) Does the distance between the flag angles / angle mount equal door width plus 3-3/8" to
3-1/2"?
4.) Do the counterbalance lift cables have equal tension? Adjust if necessary.
5.) Rewind the spring(s).
6.) Make sure door is not rubbing on jambs.
IMPORTANT: IF DOOR STILL DOES NOT BALANCE PROPERLY, THEN CONTACT A TRAINED
DOOR SYSTEM TECHNICIAN.
