Wayne-Dalton DS-100 Checking and Adjusting Spring Balance, DS-75 Mini ‘Z’ Stop-Clip Attachment

STEP 9 CHECKING AND ADJUSTING SPRING BALANCE

WARNING

Spring tension can cause curtain assembly to rotate rapidly, possibly resulting in severe or fatal injury. To prevent such injury, securely hold curtain assembly to prevent rotating.

Move the door up and down to check for proper spring tension. If the door lowers easily and raises hard, more spring tension is required. If the door lowers hard and raises easily, less spring tension is required. If a tension adjustment is necessary, secure the door in position and remove the bottom bar stops. Carefully roll the curtain all the way up without letting go of the bottom bar. Tie a rope around the curtain roll and slowly rotate the curtain roll in the opposite direction as tension was applied until spring is neutral. Change the location of the spring attachment bolt in the required direction as shown. Repeat STEPS 6, 7, 8, and 9. See STEP #12 for Tension-Pro™ bracket spring tension adjustment.

WARNING

Securely hold curtain assembly until bottom bar stop fasteners have been tightened. If not securely held, curtain could rotate, possibly causing severe or fatal injury.

STEP 10 INSTALLING LIFT HANDLE, STOP CLIPS AND OPTIONAL SLIDE BOLT LOCKS

Install a lift handle in the center of the bottom bar using 1/4-20 x 5/8” carriage bolts and flange nuts, placed so the nut is on the coil side, or inside of door as shown. If the opening width is greater than 5 foot and the door does not have slide bolt locks, install a second lift handle on the right hand side of the bottom bar (outside looking in). Install 1/4-20 x 5/8” carriage bolts and flange nuts in all remaining bottom bar holes.

I: DS-75 Mini ‘Z’ Stop-Clip Attachment:

For DS-75 mini doors, install the ‘Z’ stop-clip as shown on the right. Since the stop-clip has a retaining tab on top, it only requires one bolt to secure it to the bottom bar. Repeat assembly procedure for both sides.
