Without a properly installed safety reversal system, persons
(particularly small children) could be SERIOUSLYINJUREDor
KILLEDby a closing garage door.
* Incorrect adjustment of garage door travel limits will interfere
with proper operation of safety reversal system.
* NEVERuse force adjustments to compensate for a binding or
sticking garage door.
. After ANY adjustments are made, the safety reversal system
MUST be tested. Door MUST reverse on contact with
1-1/2" (3.8 cm) high object (or 2x4 laid flat) on floor.
Adjust the position of the door by using the black and purple
buttons. Black moves the door UP (open) and purple moves the
door DOWN(close).

desired UP (open) position (Figure 2).

the UP (open) limit and begins closing the door.

releaseeither the black or purple button. This will stop the
door.

position.
7. Push the remote control or (Figure 3). This sets the DOWN
