Setting Spring Tension
See chart below for proper spring tension setting.
Beginning with the right hand side, ensure the
counterbalance cable is in the first groove of the cable drum.
NOTE: Apply light pressure to the canoe clip on counter
while winding springs.
Using a power drill (high torque/gear reduced to 1300 RPM
preferred) with a 7/16" socket driver, carefully rotate right
hand winding bolt clockwise, until counter shows 2-3 turns.
This will keep the counterbalance cable taut while adjusting
the left hand side counterbalance cable.
Adjust left hand counterbalance cable tension (Refer to step
10).
NOTE: Single spring applications require no spring winding
on left hand side, but need cable tension adjusted.
IMPORTANT! 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 10.
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 or the number record during the Pre-Installation
Inspection on page II.
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 or the number record during the Pre-
Installation Inspection on page II. Then return to the right
hand side and wind the right hand spring to the required
number of turns for your door or the number recorded
during the Pre-Installation inspection on page II.
IMPORTANT! DO NOT OVERWIND.
After spring is wound, hold the lock nut (in back of end
bracket) stationary 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 on
double spring Torquemaster
® systems.
IMPORTANT! CAUTIOUSLY REMOVE VICE CLAMPS FROM
VERTICAL TRACKS. ADJUSTMENTS TO THE RECOMMENDED
NUMBER OF TURNS MAY BE REQUIRED. IF DOOR RAISES OFF
FLOOR UNDER SPRING TENSION ALONE, THEN REDUCE UNTIL
RESTS ON FLOOR. IF IS HARD RAISE OR DRIFTS DOWN ITS
OWN, ADD TENSION. AN UNBALANCED CAN CAUSE IDRIVE
®
OPERATION PROBLEMS.
IMPORTANT! IF YOU ARE INSTALLING THE IDRIVE ®
OPENER ON A NEW GARAGE DOOR, REAR SUPPORTS WILL
NEED TO BE FABRICATED/ INSTALLED TO SUPPORT THE
HORIZONTAL TRACKS. REAR SUPPORTS ARE CONSTRUCTED
USING PERFORATED ANGLES, HEX HEAD BOLTS/NUTS AND
THEN THE MUST BE SECURELY ATTACHED TO SOUND
FRAMING MEMBERS WITH LAG SCREWS. FOR DETAILED
INFORMATION ON CONSTRUCTING/ SUPPORTING THE REAR
SUPPORTS, REFER TO YOUR DOORS INSTALLATION
