hardware, ALL of which are under EXTREME tension.
• Disable ALL locks and remove ALL ropes connected to garage door BEFORE installation and
operating garage door opener to avoid entanglement.

unexpectedly. NO ONE SHOULD CROSS THE PATH OF THE MOVING DOOR.
To prevent damage to garage door and opener:
• ALWAYS disable locks BEFORE installing and operating the opener.

Complete the following test to make sure the garage door is balanced and is not sticking or binding.
1. Lift the door halfway up. Release the door. If balanced, it should stay in place, supported entirely by
its springs.
