1.
Door balance.
• With the door closed, pull emergency release
knob (Carriage Lock) towards the opener to
release door from carriage assembly.
• Raise door manually approximately 3’- 4’ and
release.
– Door should remain stationary or move very
slightly.

DOOR SYSTEM TECHNICIAN.
• Close the door.
• Pull emergency release knob towards door to
engage carriage.
– Operate door using remote.
– Door will re-attach itself to carriage assembly.
To reduce the risk of severe injury or death:
1.
READ AND FOLLOW ALL INSTRUCTIONS.
2. Never let children operate or play with the door controls. Keep the remote control away from children.
3. Always keep the moving door in sight and away from people and objects until the door is completely
closed. NO ONE SHOULD CROSS THE PATH OF THE MOVING DOOR.
4. NEVER GO UNDER A STOPPED, PARTIALLY OPEN DOOR.
5. Test opener monthly. The door MUST reverse on contact with a 1-1/2" high object (or a 2" x 4" board laid
flat) at the center of the doorway on the floor. After adjusting either the force or the limit of travel, retest
the door Opener. Failure to adjust the Opener properly may cause severe injury or death.
6. When possible, use the emergency release only when the door is closed. Use caution when using this
release with the door open. Weak or broken springs are capable of increasing the rate of door closure
and increasing the risk of severe injury or death.
7. KEEP DOORS PROPERLY BALANCED. See your garage door Owner’s Manual. An improperly balanced
door increases the risk of severe injury or death. Have a trained door system technician make repairs to
cables, spring assemblies, and other hardware.
