Adjustment
Introduction
Without a properly installed safety
reversal system, persons (particularly
small children) could be SERIOUSLY
INJURED or KILLED by a closing
garage door.
• Incorrect adjustment of garage door
travel limits will interfere with proper
operation of safety reversal system.
• 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 fl at) on fl oor.
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
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.
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.
