ADJUSTMENT STEP 2
Settingthe Force
The force setting measures the amountof force required to
open and close the door.
1. Push the purple button twice to enter into the Force Adjustment
Mode. The LEDwill flash quickly.
2. Push the door control or programmed remote control. The door
will close (DOWN).
3. Push the door control or programmed remote control again.
The door will open (UP).
4. Push the door control or programmed remote control a third
time to close the door (DOWN).
The LEDwill stop flashing when the force has been programmed.
The door must travel through a complete cycle, up and down, in
order for the force to be set properly. If the garage door opener
cannot open and close the door fully, inspect the door to ensure
that it is balanced properly and is not sticking or binding.
If the door is not stopping exactly where you would like it,
repeat Program the TravelLimits.
Without a properly installed safety reversal system, persons
(particularly small children) could be SERIOUSLYINJUREDor
KILLEDby a closing garage door.
• Too much force on garage door 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.
