NOTE:
Drill 3/16” pilot holes into header for the lag screws.
To locate the center bracket bushing assembly, mark the header halfway between the flag
angles and level the TorqueMaster® spring tube. Fasten the center bracket bushing assem-
bly to the header using (2) 5/16” x 1-5/8” lag screws.

Securing Door For Winding Spring(s)
20
With the door in the fully closed position, place locking pliers onto both vertical tracks just
above the third track roller. This is to prevent the garage door from rising while winding
spring(s).
NOTE:
Check the following before attempting to wind spring(s):
a. Counterbalance lift cables are secured at bottom corner brackets.
b. Counterbalance lift cables are routed unobstructed to cable drums.
c. Counterbalance lift cables are correctly installed and wound onto cable lift drums.
d. TorqueMaster
®
spring tube is installed correctly.
e. Review the label attached to the spring warning tag, to determine number of spring turns
required.
NOTE:
Door MUST be closed and locked when winding or making any adjustments to the
spring(s).
WARNING
FAILURE TO PLACE LOCKING PLIERS ONTO VERTICAL TRACK CAN
ALLOW DOOR TO RAISE AND CAUSE SEVERE OR FATAL INJURY.

Adjusting Counterbalance Lift Cable
21
Starting on the right side, adjust the cable drum assembly by rotating the drum until the set
screw faces directly away from the header. The position of the cam peak on the TorqueMas-
ter
®
spring tube should be pointing straight up.
Loosen the set screw no more than 1/2 turn. Ensure counterbalance lift cable is aligned and
seated in the first and second grooves of the cable drum. Pull on the end of the cable to
remove all cable slack.
Snug the set screw and then tighten an additional 1-1/2 turns. Measure approximately 6” of
cable and cut off excess cable. Insert end of the cable into the hole of cable drum. Repeat for
left hand cable drum assembly.
IMPORTANT:
ENSURE THE COUNTERBALANCE LIFT CABLE IS SEATED IN THE FIRST
GROOVE OF THE CABLE DRUM PRIOR TO WINDING SPRINGS.

IMPORTANT:
VERIFY THAT THERE ARE NO OBSTRUCTIONS IN THE TRAVEL PATH OF THE
DOOR SECTIONS OR COUNTERBALANCE LIFT CABLES.
IMPORTANT:
INSPECT EACH COUNTERBALANCE LIFT CABLE MAKING SURE IT IS SEATED
PROPERLY ONTO THE CABLE DRUM AND THAT BOTH COUNTERBALANCE LIFT CABLES HAVE
EQUAL TENSION.
PRIOR TO WINDING SPRING(S), CHECK COUNTERBALANCE LIFT CABLES FOR EQUAL
TENSION:
1. Attach locking pliers to track above top roller.
2. Grasp cable at approximate mid-door height location.
3. Draw cable toward you about 1/2” to 1” and release, noting the response of the cable.
4. Repeat above steps for other cable.
5. Adjust cable tension as needed until right and left cables both respond the same.
WARNING
WINDING SPRING IS AN EXTREMELY DANGEROUS PROCEDURE
AND SHOULD BE PERFORMED ONLY BY A TRAINED DOOR SYSTEM
TECHNICIAN USING PROPER TOOLS AND INSTRUCTIONS.
WARNING
IT IS RECOMMENDED THAT LEATHER GLOVES BE WORN WHILE WINDING
SPRINGS. FAILURE TO WEAR GLOVES MAY CAUSE INJURY TO HANDS.
NOTE:
A 3” ratchet extension is recommended for added clearance from the horizontal track
angle.
IMPORTANT:
PAWL KNOB MUST BE IN UPPER POSITION TO ADD / REMOVE REQUIRED
NUMBER OF SPRING TURNS.
There are two methods for counting the spring turns as you wind. One method is to 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. The other
method is to make a mark on the winding shaft (or socket) and end bracket, and count your
turns in this manner.
Check the label attached to the spring warning tag or the Winding Spring Turn Chart (below)
for the required number of complete turns to balance your door.
Starting on the right hand side, turn the pawl knob on the end bracket to the upper position.
Using a ratchet wrench with a 5/8” socket and a 3” ratchet extension, wind the spring by
rotating the winding shaft counter clockwise, while watching either the black tooth on the
