Introduction
Without a properly installed safetyreversal system, persons (particularly small children) could be
SERIOUSLY INJURED or KILLED bya closing garage door.
l
Incorrectadjustment ofgarage door travel limits will interfere with proper operation of safety
reversal system.

After ANY adjustments are made, the safetyreversal system MUSTbe tested. Door MUST reverse
on contact with 1-1/2" (3.8 cm) high object(or 2x4 laid flat) on floor.
To preventdamage to vehicles,be sure fully open door provides adequate clearance.
Your garage door opener is designed with electroniccontrols to make setup and adjustments easy. The
adjustments allow you to program where the door will stop in the open (UP) and close (DOWN) position.
The electronic controls sense the amountofforce required to open and close the door. The force is
adjusted automatically when you program the travel.
NOTE: If anything interferes with the door’s upward travel it will stop. If anything interferes with the door’s
downward travel, it will reverse.

When setting the UP travel for a one-piece door ensure that the door does not slant backwardswhen
fully open (UP). Ifthe door is slanted backwards thiswill cause unnecessary bucking and/or jerking when
