Engage the drill with the

socket) into the drive shaft of the winding unit to
wind the spring. See Table c for the total number
of winds required for your spring(s).
If you have a door with one spring:
After securing the left and right drums, finish
winding the left spring to the specified number of
winds.
If you have a door with two springs:
After securing the left and right drums, there will
be one or two winds on the left spring. proceed
with winding the right side to the specified number
of winds. Go to the left side and finish winding
the spring to the specified number of winds.
The number of spaces between stripes on
the spring equals the number of winds on the
spring. (fIG. 16)
ImPORTANT: lift the door 3"- 4" off of the
ground. Starting on the right hand side,
tighten the set screw that was not previously
tightened in Step 8. Repeat this procedure for
the left hand side.
The exact number of winds may be adjusted by
adding up to
1
/
4
winds or subtracting
1
/
wind
as compared to Table b. Lift the door by hand
with the automatic door opener disconnected
(if so equipped). If the door lifts by itself or lifts
too easily, reduce the number of winds (drill in
reverse/counterclockwise). If the door is too hard
to lift, increase (drill in forward/clockwise) the
number of winds.
