NOTE:
If your springs have stenciling, then skip this step.
Draw a chalk line horizontally along the center of the torsion spring coil(s). As the torsion
spring is wound, the chalk line will create a spiral. This spiral can be used to count and
determine the number of turns that are applied on the torsion spring.

Securing Door for Spring Winding
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
springs.
NOTE:
Check the following before attempting to wind torsion 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. Counterbalance lift cables are taut and have equal tension on both sides.
e. Cable lift drums are against end bearing brackets and set screws are tight.
f. Torsion spring or springs are installed correctly.
g. 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
torsion spring(s).
WARNING
FAILURE TO ENSURE DOOR IS IN A CLOSED POSITION AND TO PLACE
LOCKING PLIERS ONTO VERTICAL TRACK CAN ALLOW DOOR TO RISE
AND CAUSE SEVERE OR FATAL INJURY.

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
USE ONLY SPECIFIED WINDING BARS, AS STATED IN STEP
SECURING DOOR FOR SPRING WINDING. DO NOT SUBSTITUTE WITH
SCREWDRIVERS, PIPE, ETC. OTHER TOOLS MAY FAIL OR RELEASE FROM
THE SPRING CONE AND CAUSE SEVERE OR FATAL INJURY.
WARNING
PRIOR TO WINDING THE SPRING, ENSURE YOU’RE WINDING IN THE
PROPER DIRECTION AS SHOWN BELOW. OTHERWISE THE SPRING
FITTING MAY RELEASE FROM SPRING AND RESULT IN SEVERE OR FATAL
INJURY.
Position a ladder slightly to the side of the spring so that the winding cone is easily acces-
sible, and so your body is not directly in line with the winding bars.
Check the label attached to the spring warning tag for the required number of complete turns
to balance your door.
HOW TO WIND TORSION SPRINGS:
1. Insert one winding rod snugly into winding cone, to full socket depth
2. Maintaining a tight grip on the winding rod rotate it slowly in the proper direction, as
shown below.
3. If there is any slippage of the winding rod in the winding cone socket, reverse the direction
of winding and return the cone to its original position. Remove the winding rod from the
winding cone socket. Reseat the winding rod in the socket. Start over at Step #1.
4. When the winding rod is vertical above the winding cone, insert another winding rod into
one of the other sockets, being careful to seat it snugly and at full socket depth.
5. Hold the spring with the second winding bar, and remove the first.
6. Repeat Steps #2 through #5 until the complete turns have been applied.
IMPORTANT:
AFTER WINDING THE SPRING(S), TIGHTEN THE SET SCREWS IN THE WINDING
CONE TO 14-15 FT-LBS OF TORQUE (ONCE SET SCREWS CONTACT THE TORSION SHAFT,
TIGHTEN SCREWS AN ADDITIONAL 1/2 TURN FOR SOLID SHAFT AND ONE FULL TURN FOR
TUBULAR SHAFT).
