Counterbalance Cable Aligned
and Seated In The First Groove Starting on the right hand side, rotate the
cable drum until the set screw faces directly
away from the header. Torque tube cam peak
should be pointing straight up.
NOTE: Illustrations show the right hand cable
drum, left hand cable drum is symmetrically
opposite.
NOTE: Cable tension is set during the initial
door installation. If there is slack between the
counterbalance cable and the cable drum or
unequal tension between the right and left
hand counterbalance cables, the
counterbalance cables will have to be
readjusted. If there is no slack and cable
tension is equal, proceed to Step 11.
Loosen the set screw no more than 1/2 turn.
Using locking pliers, pull on the end of the
cable to remove all cable slack.
Check to ensure the cable is aligned and
seated in the appropriate groove(s) of the
cable drum. Snug the set screw, and then
tighten an additional 1-1/2 turns. Left side will
be
adjusted in Step 12.
IMPORTANT! ENSURE THE CABLE IS ALIGNED
AND SEATED IN THE APPROPRIATE GROOVE(S)
OF THE CABLE DRUM PRIOR TO WINDING
SPRINGS.

excess cable, tuck end into cable drum
(Torquemaster
® ) or insert end in hole of cable
drum (Torquemaster ® Plus).
