Wayne-Dalton IDRIVE 3982 - Manual (Page 11)

Now that the counterbalance system is installed to the
garage door, remove the locking pliers and carefully
lower the door to the fully closed position. Be sure
the door descends uniformly by pulling the door down
from the center of the door and using correct gripping
points, such as a lift handle or lock handle.
WARNING
TO AVOID SEVERE IN-
JURY DO NOT PLACE FINGERS OR HAND
BETWEEN SECTION JOINTS.
Once the door is closed, measure the spring length on
both springs and verify the spring tension length is the
same for both springs. If they are not, raise the door,
re-attach locking pliers and repeat the CABLE ADJUSTMENT process in Step8.
IMPORTANT! Do not try to adjust springs while the door is in the closed (Down) position.
Ensure that the safety cables installed on your door are not tangled with the extension spring cables. Contact
a professional garage door service technician if safety cables are not installed through each of the extension
springs on your door.

Attach the 3-hole clip as shown. Insert the S-hook into the 3-hole clip. Pull the
cables taut ensuring the cable is on the sheave. Connect the cable to the hori-
zontal angle. Repeat Step 8 for the opposite side of the door.
After the counterbalance cables are installed on both sides of the track, lift the
drum wrap to remove the shrink wrap from the cable drums. Re-insert the drum
wrap and match the hole in the drum wrap with the hole in the fl ag bracket.
Secure the drum wrap to the fl ag bracket using (1) 1/4-20 x 9/16” track bolt and
1/4-20 fl ange nut (see Fig.7). Repeat for the other side.
SPRING ADJUSTMENTS: Adjust the counterbalance cables so that there is
no more than 1” of spring stretch. This is done by adjusting the cable in the 3-
hole clip and/or moving the S-hook to another location on the horizontal angle.
Be sure that the left and right side counterbalance cables are adjusted to provide
the same amount of spring pre-tension on each side.
