STEP 2: Adjusting the Sensitivity Force — Sensitivity System force adjustment screws are located on the side rails of the Power
Unit and can easily be adjusted with a screwdriver. Turn the screws CLOCKWISE for more force and COUNTERCLOCKWISE
for less force.
STEP 3: Testing the Sensitivity Force — To test the Sensitivity System, start the Opener and grasp the bottom door handle halfway
through the door's travel (opening or closing). When testing in the CLOSE direction, a second person will be needed to maintain
pressure on the Push Button IF an Auxiliary Entrapment Protection Device has not yet been fitted. If a second person is unavailable,
use a stiff cardboard carton placed in the door's downward path to indicate the force the Opener is exerting. If the force adjustment
screws are properly set, the door should stop if opening, and reverse if closing without exerting undue pressure.
WARNING
IMPROPER ADJUSTMENT OF SENSITIVITY SYSTEM
FORCE COULD CAUSE ENTRAPMENT, INJURY OR
DEATH. SET ADJUSTMENTS FOR JUST ENOUGH
FORCE TO OPERATE THE DOOR RELIABLY, BUT NO
STRONGER. Contact a service professional to correct
any binding, sticking or other door problems. DO NOT
OVER-ADJUST SENSITIVITY SYSTEM TO
COMPENSATE FOR A POORLY WORKING DOOR.
WARNING
THE SENSITIVITY SYSTEM REVERSING TEST SHOULD BE
PERFORMED MONTHLY TO ENSURE THAT THIS IMPORTANT
SYSTEM REMAINS IN PROPER ADJUSTMENT.
WARNING
FAILURE TO TEST
REVERSING SYSTEM
COULD RESULT IN
DEATH OR SERIOUS
INJURY. TEST THIS
SYSTEM ONCE A MONTH

STEP 4: Testing the Opener’s
Reversing System — To test the
Opener's Reversing Feature at floor level,
place a solid object 1-1/2" thick (such as a
standard 2 X 4 board laid flat) on the
ground where the center of the door will
contact it. Close the door. If the down
force adjustments are correct, the door
will reverse within two seconds of
contacting the object and travel to the Full
Open position. If this does not occur,
recheck the Limit Adjustments (Page 17)
and Sensitivity Adjustments (Step 2 & 3,
Above).
NOTE:
Any time adjustments are
made to Limits or Sensitivity, YOU
MUST RETEST THE OPENER FOR
THE REVERSING FEATURE AT
FLOOR LEVEL AS OUTLINED
ABOVE.
