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 14-15 ft. lbs. of torque (once set screws contact the torsion shaft, tighten screws one full turn).

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 over-wound, carefully remove the locking pliers from the torsion shaft and vertical tracks.

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.

Perforated Angle Gauge Weight Limitations:

1-1/4” x 1-1/4” x 16 Gauge Door Weight Less Than 175 lbs.

NOTE: If an opener is installed, position horizontal tracks one hole above level when securing it to the rear back hangs.

WarningARNING

Keep horizontal tracks parallel and within 3/4” to 7/8” maxi- mum of door edge, otherwise door could fall, resulting in severe or fatal injury.

Important: Do not support the weight of the door on any part of the rear back hangs that cantilevers 4” or more beyond a sound framing member.

Note: If rear back hangs are to be installed over drywall, use (2) 5/16” x 2” hex head lag screws and make sure lag screws engage into solid structural lumber.

Note: 26” angle must be attached to sound framing members and nails should not be used.

Now, permanently attach the weatherstrips on both door jambs and header. The weather- strips were temporarily attached in Preparing the Opening, in the pre-installation section of this manual.

NOTE: When permanently attaching the weatherstrips to the jambs, avoid pushing the weath- erstrips too tightly against the face of door.

IMPORTANT: CHECK THE WARNING TAG(S) ATTACHED TO THE SPRING(S)

FOR THE REQUIRED NUMBER OF COMPLETE TURNS, TO BALANCE YOUR DOOR.

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.

Now, lift door and check its balance. Adjustments to the required number of spring 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. A poorly balanced door can cause garage door operator operation problems.

Important: Hold the door down to prevent it from rising unexpectedly in the event the spring(s) was over-wound and cautiously remove vice clamps from vertical tracks.

Raise the door until the top section and half of the next section are in the horizontal track radius. Do not raise door any further since rear of horizontal tracks are not yet supported.

WarningARNING

Raising door further can result in door falling and cause severe or fatal injury.

Clamp a pair of vice clamps onto the vertical tracks just above the second track roller on one side, and just below the second track roller on the other side. This will prevent the door from raising or lowering while installing the rear back hangs.

Using the chart (Perforated Angle Gauge Weight Limitations) below, use the appropriate perforated angle (may not be supplied), (2) 5/16” x 1-5/8” hex head lag screws and (3) 5/16” bolts with nuts (may not be supplied), fabricate rear back hangs for the horizontal tracks. Attach the horizontal tracks to the rear back hangs with 5/16” - 18 x 1” hex bolts and nuts (may not be supplied). Horizontal tracks must be level and parallel with door within 3/4” to 7/8” maximum of door edge.

WarningARNING

Exceeding the recommended listed door weight limitations of specific gauge perforated angles may result in door falling when raised, causing severe or fatal injury.

WarningARNING

Verify perforated back hang angle load ratings with back hang angle supplier.

Perforated Angle Gauge Weight Limitations:

Perforated Angle Gauge	Door Weight
2” x 2” x 12 Gauge	Door Weight Less Than 800 lbs.
1-1/4” x 1-1/4” x 13 Gauge	Door Weight Less Than 305 lbs.
1-1/4” x 1-1/4” x 15 Gauge	Door Weight Less Than 220 lbs.

To adjust spring tension, fully close door. Apply vice grips to track above third track roller. Insert a winding rod into the winding cone. On single spring doors, counterbalance lift cable tension must be maintained by placing vice grips on torsion shaft before loosening set screws in the winding cone. Push upward on the winding rod while carefully loosening the set screws in the winding cone. 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 in the winding cone and repeat for the other side. Recheck door balance. DO NOT ADJUST MORE THAN 1/2 TURN FROM THE RECOMMENDED NUMBER OF TURNS.

If the door still does not operate easily, lower the door into the closed position, UNWIND THE SPRING(S) FULLY (Reference the insert “Removing The Old Door / Preparing The Opening” section on torsion spring removal) and recheck the following the items:

1.) Check the door for level.

2.) Check the torsion shaft for level.

3.) Check the track spacing.

4.) Check the counterbalance cables for equal tension and proper wrap onto the cable drums.

5.) Check the track for potential obstruction of the track rollers.

6.) Clamp locking pliers onto track and rewind springs.

IMPORTANT: If door still does not operate properly, then contact a trained door system technician.
