how far the screen goes down and up.

screw head).

with your screen.

end of the wand needs to go into the screw head of the limit switch you want to 

adjust.

6. Adjusting for the up limit position: When the screen retracts and you want to 

change the position of where the bottom bar stops, use the adjusting tool to turn 

the switch in the CW direction to make the screen drop more, and turn it in the 

CCW direction and the screen will rise more into the casing. To see the result of the 

adjustment, extend the screen all the way and then retract the screen to see the

down direction as that will also 

damage the screen.
