IMPORTANT SAFETY INSTRUCTIONS

To reduce the risk of severe injury or death to persons:
1. READ AND FOLLOW ALL INSTRUCTIONS.
2. Do not permit children either to operate or to play with the opener. Keep remote control in a
location inaccessible to children.
3. Operate opener only when the door is in full view and free from any obstruction. Keep the door in
sight until it is completely closed. NO ONE SHOULD CROSS THE PATH OF THE MOVING DOOR.
4. Check safety reversal system monthly. See page 30. The garage door MUST reverse on contact
with a one-inch (or a 2x4 board laid flat) object placed on the floor. If an adjustment is made to
either the force or the limit of travel, both adjustments may be needed and the safety reversal
system must be checked. Failure to properly adjust the opener may result in severe injury or death.
5. If possible, use the emergency release only when the door is in a closed position. Caution should
be taken whenever the disconnect cord is actuated with the door open. Weak or broken springs
may cause the door to fall rapidly, causing injury or death to persons.
6. KEEP GARAGE DOORS PROPERLY BALANCED. See page 3. An improperly balanced door may not
reverse when required and could result in severe injury or death. Repairs to cables, spring
assemblies and other hardware must be made by a professional garage door person.
7. Disconnect the electric power to the garage door opener before making any repairs or removing the
covers.
SAVE THESE INSTRUCTIONS.
