Preparing your garage door Before you begin: • Disable locks. • Remove any ropes connected to garage door. • Complete the following test to make sure your garage door is balanced and is not sticking or binding: 1. Lift the door about halfway as shown. Release the door. If balanced, it should stay in place, supported entirely by its springs. 2. Raise and lower the door to see if there is any binding or sticking. If your door binds, sticks, or is out of balance, call a trained door systems technician.
Planning • Do you have an access door in addition to the garage door? If not, Model 7702CB Outside Quick Release is required. See Accessories page. • Look at the garage door where it meets the floor. Any gap between the floor and the bottom of the door must not exceed 1/4". Otherwise, the safety reversal system may not work properly. See Adjustment Step 3. Floor or door should be repaired. Identify the type and height of your garage door.
Planning (Continued) WARNING ONE-PIECE DOOR INSTALLATIONS • Generally, a one-piece door does not require reinforcement. If your door is lightweight, refer to the information relating to sectional doors in Installation Step 11. • Depending on your door’s construction, you may need additional mounting hardware for the door bracket (Step 11). Without a properly working safety reversal system, persons (particularly small children) could be SERIOUSLY INJURED or KILLED by a closing garage door.
