3.Lower the air pressure: Lower the air pressure to the operator. The door will not operate as quickly and the shock of the immediate reversal of the door won’t loosen the cables.
4.Restrict the air flow: Install a valve in the air line to restrict the airflow. This will slow the reaction time of the door and still maintain the desired air pressure.
5.Balance the door: Balance the door by checking spring tension or counterweight. If the springs are wound too tightly, or the counterweight is too heavy, the door may not come down properly and cable could get slack.
6.Cable keepers: This is a spring that attaches to the bottom roller shaft and hooks to the cable. It requires 11/4 inches of space between the door and the track.
7.Pusher springs: Pusher springs give a door stuck in the horizontal position a shove to get it started. These are available from most door companies, or call UPI at
