Adjustment Step 2
Adjust the Force
Force adjustment controls are located on the beck
panel of the opener. Force adjustment set'rings
regulate the amount of power required to open end
close the door.
The door will stop in the up direction if anything
interferes with its travel. The door will reverse in the
down direction if anything interferes with itstravel
(including binding or unbalanced doors).
Ifthe forces are set too light, door travel may be
interrupted by nuisance reversals in the down
direction end stops in the up direction. Weather
conditionscan affect the door movement, so
occasional adjustment may be needed.
The maJdmumforce adjustment range is 260 degrees,
about 3/4 of a complete rum. Do not force controls
beyond that point. Tum force adjustment controls
with a screwdriver.

when required and could seriously Injure or Idll
someone under It. Do not Inoreaos the force
beyond the minimum amount required to close
the doer. Do not use the force adjustments to
compensate for • binding or sticking garage
door. Test the safety reverse system following
all adjustments to force levels. See page 30.
How and When to Adjust the Forces
Test the DOWN (close) force
Grasp the door bottom when the door is about
halfway through DOWN (close) travel. The door
should reverse. Reversal halfway through down
travel does not guarantee reversal on a two.inch
obstruction. See page 30. If the door is hard to
hold or doesnt reveme, decrease the DOWN (close)
force by turning the control counterclockwise.
Make 10 degree rum adjustments until the door
reverses normally. After each adjustment, run the
opener through a complete cycle.
Test the UP (open) force
Grasp the door bottom when the door is about
halfway through UP (open) travel. The door should
stop. if the door is hard to hold or doesn't stop,
decrease UP (open) force by turning the control
counterclockwise.
Make 10 degree tum adjustments until the door stops
easily. After each adjustment, run the opener through
a complete travel cycle.
If the doer doesn't open at least 5 feet _J
Increase UP (Open) force by turning the control
clockwise. Make 10 degree turn adjustments u_til
door opens completely. Re-adjust the UP limit if
necessary. After each adjustment, run the opener
through a complete travel cycle.
If the doer reverses during the down (close) cycle
and the opener lights aren=t flashing
Increase DOWN (close) force bytuming the control
clockwise. Make 10 degree turn adjustments untilthe
door completes a close cycle. After each adjustment,
run the opener through a complete travel cycle. Do
not Increase the force beyond the minimum
amount required to close the doer.
