Introduction
Without a properly installed safety reversal system,persons (particularly small children) could be
SERIOUSLY INJURED or KILLED by a closing garage door.
l Incorrect adjustment of garage door travel limits will interfere with proper operation of safety
reversal system.
l After ANY adjustmentsare made, the safety reversal system MUSTbe tested. Door MUST
reverse on contact with 1-1/2" (3.8 cm) high object (or 2x4 laid flat) on floor.
To prevent damage to vehicles, be sure fully open door provides adequate clearance.
Your garage door opener is designed with electronic controls to make setup and adjustmentseasy. The
adjustmentsallow you to program where the door will stop in the open (UP) and close (DOWN)
position. The electronic controls sense the amount of force required to open and close the door. The
force is adjusted automatically when you program the travel.
NOTE: Ifanything interferes with the door’s upward travel it will stop. If anything interferes with the
door’s downward travel, it will reverse.
UP (Open)
DOWN (Close)
One-Piece Doors Only
When setting the UP travel for a one-piece door ensure that the door does not slant backwards when
fully open (UP). Ifthe door is slanted backwards this will cause unnecessary bucking and/or jerking
when the door is opening or closing.
