Tools Needed:
Power Drill
7/16" Socket
Driver
Winding Bolt Rotation
See chart in Step 32 for proper spring tension setting.
Beginning with the right hand side, ensure the cable is in the first groove of the cable drum. Apply light pressure to the canoe clip on counter cover while winding springs.
Using a power drill (high torque/gear reduced to 1300 RPM preferred) with a 7/16" socket, carefully rotate right hand winding bolt clockwise, until counter shows
This will keep the counterbalance cable taut while adjusting the left hand side counterbalance cable. Adjust left hand counterbalance cable tension. (refer to Step 30)
NOTE: Single spring applications require no spring winding on left hand side, but need cable tension adjusted.
NOTE: Ensure counterbalance cable tension is equal for both sides prior to fully winding spring(s) to appropriate number of turns. If cable tension is unequal refer to Step 30.

WARNING
Prior to winding or making adjustments to the springs, ensure 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.

Setting Spring Tension
NOTE: Apply light pressure to the canoe clip on the counter cover while winding spring(s).
See the Spring Turn chart.
For SINGLE SPRING applications, return to the right hand side and carefully rotate the winding bolt head clockwise until the counter shows the correct number of turns for your door.
For DOUBLE SPRING applications, remain on the left hand side and carefully rotate the winding bolt head clockwise until the counter shows the correct number of turns for your door. Then return to the right hand side and wind the right hand spring to the required number of turns.
IMPORTANT: Do Not Overwind.
After spring is wound, hold the lock nut (in back of end bracket) stationary on the right hand side with a 7/16” wrench while rotating the winding bolt clockwise until snug. Tightening of the lock nut prevents spring from unwinding. Repeat for opposite side for double spring TorqueMaster® systems.
IMPORTANT: Cautiously remove vice clamps from vertical tracks. Adjustments to the recommended number of turns may be required.
AFTER REAR SUPPORT ASSEMBLY IS COMPLETE (STEP 34), CHECK DOOR BALANCE. If door raises off floor under spring tension alone, Reduce spring tension until door rests on the floor. If the door is hard to raise or drifts down on its own, add spring tension. An unbalanced door such as this can cause idrive® operation problems.
