SPRING ADJUSTMENTS
Release the locking pliers from vertical tracks and check the door’s counterbalance. Adjust springs if necessary. If door does not balance properly, verify that all supplied
components such as struts are installed. Verify quantity, wire diameter, spring size & drums to the spring tag. Check Cable length. Add or subtract up to one turn on the
springs. Contact Wayne-Dalton Corp. if problem persists.
FINAL ADJUSTMENTS
Vertical tracks can now receive fi nal adjustments. Open and close the door a few times, checking and adjusting side clearance (if necessary). Tighten jamb fasteners (lags,
self drilling, or anchors) to permanently secure verticals. Adjust door in or out from jamb by loosening the track to obtain proper seal. Permanently tighten all track bolts.
Lubricate springs, rollers, and bearing with oil. DO NOT GREASE THE INSIDE OF THE TRACK.
