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 (2) SET SCREWS TO 14-15
FT. LBS. OF TORQUE IN THE WINDING CONE. ONCE SET SCREWS CONTACT THE SHAFT,
TIGHTEN SCREWS ONE FULL TURN.
HIGH SPRING TENSION CAN CAUSE
SERIOUS INJURY OR DEATH.
DO NOT
adjust, repair or remove springs or parts to
which springs are connected, such as steel brack-
ets, cables, wood blocks, fasteners or other parts of
the counterbalance system.
Adjustments or repairs must
ONLY
be made by a
trained door systems technician using proper tools
and instructions.
DO NOT
remove, cover or paint over this tag. Prod-
uct user should inspect this tag periodically for
legibility and should order a replacement tag from
the door manufacturer, as needed.

Attaching Rear Back Hangs
22
IMPORTANT:
HOLD THE DOOR DOWN TO PREVENT IT FROM RISING UNEXPECTEDLY IN THE
EVENT THE SPRING(S) WERE OVER-WOUND AND CAUTIOUSLY REMOVE LOCKING PLIERS
FROM VERTICAL TRACKS.
Raise the door until the top section and half of the next section are in the horizontal track
radius. Do not raise door any further since rear of horizontal tracks are not yet supported.
WARNING
RAISING DOOR INTO THE LOOSE HORIZONTAL TRACKS CAN RESULT IN
DOOR FALLING AND CAUSE SEVERE OR FATAL INJURY.
Clamp a pair of locking pliers onto the vertical tracks just above the second track roller on
one side, and just below the second track roller on the other side. This will prevent the door
from raising or lowering while installing the rear back hangs.
Using the chart below, select the appropriate perforated angle (may not be supplied). Fabri-
cate and install rear back hangs, as shown.
Perforated Angle Gauge Weight Limitations:
Perforated Angle Gauge
Door Balance Weight
2” x 2” x 12 Gauge
Less Than 800 lbs.
1-1/4” x 1-1/4” x 13 Gauge
Less Than 305 lbs.
1-1/4” x 1-1/4” x 15 Gauge
Less Than 220 lbs.
1-1/4” x 1-1/4” x 16 Gauge
Less Than 175 lbs.
NOTE:
If an opener is installed, position horizontal tracks one hole above level when securing
it to the rear back hangs.
WARNING
MAKE SURE BACK HANGS ARE BRACED SUFFICIENTLY TO RESIST ANY
MOTION DURING SPRING APPLICATION AND DOOR TRAVEL. IF BACK
HANGS PIVOT OR DEFLECT, ADD REINFORCEMENT UNTIL THEY REMAIN
FIRM AND STATIONARY. ANY BACK HANG THAT IS BENT MUST BE
REPLACED.
WARNING
KEEP HORIZONTAL TRACKS PARALLEL AND WITHIN 3/4” TO 7/8” FROM
DOOR EDGE, OTHERWISE DOOR COULD FALL, RESULTING IN SEVERE OR
FATAL INJURY.
IMPORTANT:
DO NOT SUPPORT THE WEIGHT OF THE DOOR ON ANY PART OF THE REAR
BACK HANGS THAT CANTILEVERS 4” OR MORE BEYOND A SOUND FRAMING MEMBER.
NOTE:
If rear back hangs are to be installed over drywall, use (2) 5/16” x 2” hex head lag
screws and make sure lag screws engage into solid structural lumber.
WARNING
FAILURE TO ASSEMBLE AND ATTACH REAR BACK HANGS PROPERLY
ACCORDING TO THE ABOVE INSTRUCTIONS MAY RESULT IN DOOR
FALLING WHEN RAISED, CAUSING SEVERE OR FATAL INJURY.
NOTE:
Perforated angle must be attached to sound framing members and
nails should not
be used
.
