IMPORTANT SAFETYINSTRUCTIONS
To reduce the risk of SEVERE INJURY or DEATH:
1. READ AND FOLLOW ALL WARNINGS AND INSTRUCTIONS.
2. ALWAYS keep remote controls out of reach of children. NEVER permit children to operate or
play with garage door control push buttons or remote controls.
3. ONLY activate garage door when it can be seen clearly, it is properly adjusted, and there are no
obstructions to door travel.
4. ALWAYS keep garage door in sight and away from people and objects until completely closed.
NO ONE SHOULD CROSS THE PATH OF THE MOVING DOOR.
5. NO ONE SHOULD GO UNDER A STOPPED, PARTIALLY OPENED DOOR.
6. If possible, use emergency release handle to disengage trolley ONLY when garage door is
CLOSED. Use caution when using this release with the door open. Weak or broken
springs or unbalanced door could result in an open door falling rapidly and/or unexpectedly and
increasing the risk of SEVERE INJURY or DEATH.
7. NEVER use emergency release handle unless garage doorway is clear of persons and
obstructions.
8. NEVER use handle to pull garage door open or closed. If rope knot becomes untied, you could
fall.
9. After ANY adjustments are made, the safety reversal system MUST be tested.
10. Safety reversal system MUST be tested every month. Garage door MUST reverse on contact
with 1-1/2" (3.8 cm) high object (or a 2x4 laid flat) on the floor. Failure to adjust the garage
door opener properly increases the risk of SEVERE INJURY or DEATH.
11. ALWAYS KEEP GARAGE DOOR PROPERLY BALANCED (see page 1). An improperly
balanced door may NOT reverse when required and could result in SEVERE INJURY or
DEATH.
12. ALL repairs to cables, spring assemblies and other hardware, ALL of which are under
EXTREME tension, MUST be made by a trained door systems technician.
13. ALWAYS disconnect electric power to garage door opener BEFORE making ANY repairs or
removing covers.
