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 object (or a 2x4 board laid flat) placed on the floor. If an adjustment is made to one of the controls
(either force or limits of travel), the other control may need to be adjusted also, 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 inju O" or death to persons.
6. KEEP GARAGE DOORS PROPERLY BALANCED. See page 3. An improperly balanced door may not
reverse ,,hen 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.
