Winding Spring(s)

(Continued)

RECOMMENDED SPRING TURNS

Tools Needed:

To wind the spring, rotate the winding shaft clockwise, while watching the mark on the winding shaft (or socket). Rotate the winding shaft to the required number of turns for your door or the number recorded during the Pre-Installation Inspection on page II. Place ratchet pawl in lower position. Then return to the right hand side and wind the right hand spring to the required number of turns or the number recorded during the Pre-Installation Inspection on page II. Place ratchet pawl in lower position.

IMPORTANT! DO NOT OVERWIND SPRINGS.

NOTE: Since total turns to balance door can deviate from spring turn chart values by ± 1/2 turns, adjustments to the recommended number of spring turns may be required AFTER rear hangers assembly is completed.

IMPORTANT! CAUTIOUSLY REMOVE VICE CLAMPS FROM VERTICAL TRACKS. ADJUSTMENTS TO THE RECOMMENDED NUMBER OF TURNS MAY BE REQUIRED. IF DOOR RAISES OFF THE FLOOR UNDER SPRING TENSION ALONE, THEN REDUCE SPRING TENSION UNTIL DOOR RESTS ON THE FLOOR. IF THE DOOR IS HARD TO RAISE OR DRIFTS DOWN ON ITS OWN, THEN ADD SPRING TENSION. AN UNBALANCED DOOR 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.
