Slide each of the set collars up against the inside surface of the end bearing brackets, with the set screw facing directly away from the header. Tighten the set screw in each of the set collars to the torsion shaft to 14-15 ft. lbs. of torque (once set screw contacts the shaft, tighten set screw one full turn).

IMPORTANT: Prior to tightening the set screws in the set collars, avoid plac- ing the set screws in the keyways of torsion keyed shaft(s).

Starting on the left hand side, thread the counterbalance lift cable up and around the front side of the left hand cable drum.

IMPORTANT: Verify that there are no counterbalance lift cable obstructions.

Hook the counterbalance lift cable into the left hand cable drum. Starting on the left hand side, slide the left hand cable drum onto the torsion shaft and up against the left hand end bearing bracket. Counterbalance lift cable should provide a minimum of 1/2 pre-wrap on the cable drum. Tighten the (2) set screws in the cable drum to 14-15 ft. lbs. of torque (once set screws contact the shaft, tighten set screws one full turn).

NOTE: For doors with a torsion keyed shaft, insert (1) key shaft into the slot of both the cable drum and the slot in the torsion keyed shaft, as shown.

Rotate the left hand drum and torsion shaft until counterbalance lift cable is taut. Now attach locking pliers to the torsion shaft and brace locking pliers against the jamb to keep counter- balance lift cable taut. Repeat the same process for right hand side.

Now, secure the coupler assembly by tightening the (3) 3/8”-16 x 1-3/4” hex head screws and the (3) 3/8”-16 hex nuts.

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.

IMPORTANT: Inspect each counterbalance lift cables making sure they are seated properly onto the cable drums and that both counterbalance lift cables have equal tension.
