TENSION ADJUSTMENT
(Models 30448, 30449, and 30450 only)
To adjust the tension, push the M3 hex wrench into the adjustment hole, then push in and
turn. Turn it clockwise to tighten the tension and counterclockwise to loosen the tension.
UP AND DOWN LIMITS
The screen up and down limits are set at the factory, so normally there is no need to adjust
them. However, if the need arises, use the included motor limit setting tool to adjust the
up and/or down limits.
Turn the green limit clockwise to retract the screen less or counterclockwise to
retract the screen more.
Turn the yellow limit clockwise to extend the screen less or counterclockwise to
extend the screen more.
