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 a 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 23. The garage door
MUST
reverse on contact
with a 2x4 board laid flat 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 manual 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 could
result in severe injury or death.
Repairs to cables, spring assemblies and other hardware must be
made by a qualified person.
7. Disconnect the electric power from the garage door opener before making any repairs or removing
the covers.
8. SAVE THESE INSTRUCTIONS.
