FAILURE TO USE APPROVED
WINDING BARS CAN CAUSE
SPRING ENERGY TO BE RELEASED
SUDDENLY, RESULTING IN SEVERE
OR FATAL INJURY.
COUNTERBALANCE SPRING
TENSION MUST BE RELIEVED
BEFORE REMOVING ANY
HARDWARE. A POWERFUL
SPRING RELEASING IT’S ENERGY
SUDDENLY CAN CAUSE SEVERE OR
FATAL INJURY.
Do not release the torsion spring tension
unless you’re a qualified and experienced
door technician, but have a professional
door agency release the tension.
Step 1: Close the door and place vice
clamps to the back legs on both vertical
tracks, above the third roller to prevent
the door from lifting as you unwind the
springs. Use only approved winding bars
available from your dealer. Do not use
undersized steel rods, screw drivers or
anything else to unwind the springs.
Position the ladder just off to the side
of the winding cone. The winding cone
should be easy to reach without putting
your body directly in front of it.
Step 2: Insert a winding bar into one
of the holes in the winding cone. Exert
upward pressure. Using caution, loosen
the two (2) set screws in the winding
cone. Be prepared to support the full
torsional force of the spring when the set
screws are loosened.
Step 3: Once set screws are loose, slowly
and carefully lower the winding rod until it
rests against the door. Insert other winding
bar into the upper hole. Push up and
remove lower bar. Carefully lower upper
winding bar, one 1/4 turn at a time, until
it rests against the door. Repeat process
until all tension is relieved. If your door
is equipped with two (2) torsion springs,
follow the same procedure to relieve
tension on the second spring.
Step 4: Remove vice clamps from tracks,
unbolt entire torsion assembly and remove
from work area.
NOTE: Continue with “P4” on page 9 after
completing this step.
