properly and someone could be pinned under it. An
opening door might not stop when going up and
someone hanging on the door could be pinned between
the door and the header. Never increase the force above
the minimum required to move the door.Never adjust the
force to compensate for a sticking or binding door.
Perform this safety check once a month.
