TorqueMaster®

12		Setting Spring Tension
Tools Needed:	See chart below for proper spring tension setting.
Power Drill	Beginning with the right hand side, ensure the
	counterbalance cable is in the first groove of the cable drum.
7/16" Socket	NOTE: Apply light pressure to the canoe clip on counter
	while winding springs.
Driver
7/16" Wrench	Using a power drill (high torque/gear reduced to 1300 RPM
	preferred) with a 7/16" socket driver, carefully rotate right
Step Ladder	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
	INSTRUCTIONS AND OWNER’S MANUAL.
