ADJUSTMENT
Introduction
Your garage door opener is designed with electronic controls 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 amount of
force 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.
Without a properly installed safety reversalsystem, persons
(particularly small children) could be SERIOUSLYINJUREDor
KILLEDby a closing garagedoor.
• 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 reversalsystem
must be tested. Door MUST reverse on contact with 1-1/2"
(3.8 cm) high object (or 2x4 laid fiat) on floor.
To prevent damage to vehicles, be sure fully open door
provides adequateclearance.
ONE-PIECEDOORSONLY
When setting the UP travel for a one-piece door ensure that the
door does not slant backwardswhen fully open (UP). If the door
is slanted backwards this will cause unnecessarybucking and/or
jerking when the door is opening or closing.
