The screen stop positions are preset at the factory. Should it be necessary to adjust for more or less travel proceed as
follows. Refer to figure 4.
TO INCREASE SCREEN HEIGHT
1. Turn the white limit adjuster counterclockwise one-quarter turn at a time. Run the screen down about one foot and
then back up to test the stop position. Repeat until the desired position is set.
NOTE: Do not adjust for more height than what was ordered. Adjusting too high may cause the arms to lock and not retract
properly. There must be at least 1-1/2 wraps of fabric on the roller at all times.
TO DECREASE SCREEN HEIGHT
1. Turn white limit adjuster clockwise one-quarter turn at a time. Run the screen up to test the stop position. Lower
the screen about one foot and turn limit adjuster again. Repeat until the desired position is set.
TO ADJUST THE DOWN POSITION
1. Raise the screen about one foot and stop. Turn the red limit adjuster counterclockwise one-quarter turn to
increase the down travel.
NOTE: Do not adjust the screen down too far. This will strain the motor and screen. The lid of the box should just close when
the motor stops.
1. Turn the red limit adjuster clockwise one-quarter turn at a time to decrease the amount of down travel. Run the
screen down to test the stop position. Repeat until the desired position is set.
