SECTIONS OR COUNTERBALANCE LIFT CABLES.
NOTICE
INSPECT EACH COUNTERBALANCE LIFT CABLE MAKING SURE IT IS SEATED
PROPERLY ONTO THE CABLE DRUM AND THAT BOTH COUNTERBALANCE LIFT
CABLES HAVE ROUGHLY EQUAL TENSION.
See Figures 43 and 44 for the following steps.
20a. Attach locking pliers to track above top roller.
20b. Grasp cable at approximately mid-door height location.
20c. Draw cable toward you about 1/2" to 1" and release, noting the response of
the cable.
20d. Repeat above steps for other cable.
20e. Adjust cable tension as needed until right and left cables respond the same.

PAWL KNOB MUST BE IN UPPER POSITION TO ADD/REMOVE REQUIRED NUMBER
OF SPRING TURNS.
20f. There are two methods for counting the spring turns as you wind:
1. Identify the black tooth on the ratchet wheel inside of the end bracket. When the
wheel makes one revolution and the tooth returns to its starting point, one turn has
been made.
2. Make a mark on the winding shaft (or socket) and end bracket, and count turns
in this manner.
20g. The required number of complete turns to balance your door is 16.
20h. Starting on the right hand side, turn the pawl knob on the end bracket
to the upper position. Using a ratchet wrench
a 3" ratchet extension , wind the spring by rotating the winding shaft
4
counterclockwise, while watching either the black tooth on the ratchet wheel or the
mark on the winding shaft. After 2 to 3 turns, remove the ratchet wrench and

adjust the counterbalance lift cable
lift cables are in the first groove of the cable drums, as shown in Step Adjusting
Counterbalance Lift Cable.
NOTE: Single-spring applications require no spring winding on the left hand side,
but lift cable tension needs to be adjusted.
NOTICE
WHEN WINDING SPRING(S), ENSURE YOU ARE WINDING IN THE PROPER DIREC-
TION, AS SHOWN IN FIGURE 43 AND FIGURE 44. ENSURE THE RACHET WRENCH
WINDS THE SPRING CLOCKWISE FOR LEFT HAND SPRING. ENSURE THE RACHET
WRENCH WINDS THE SPRING COUNTERCLOCKWISE FOR RIGHT HAND SPRING.
For Single Spring Applications:
Continue winding the spring on the right side to the required number of turns for
your door.
When complete, place pawl knob in lower position.
For Double Spring Applications:
Use a counting method as described in step 20f. Place the ratchet wrench with
5/8" socket and a 3" ratchet extension onto the left side winding shaft end.
To wind the spring, rotate the winding shaft clockwise, while watching the black
tooth on the ratchet wheel or the mark on the winding shaft.
Rotate the winding shaft to the required number of winding turns for your door.
Then return to the right hand side and wind the right hand spring to the required
number of turns.
Place pawl knob in lower position on both sides.
