Modifying the extension of the screen
You can increase the extension of the screen up to 3" past the factory
preset stop, or you can decrease the extension by approximately 4-6" from
the factory preset stop. Do not attempt to modify the screen extension
beyond these recommended amounts.
The thumbwheels are located on the left side of the screen roller tube inside
the case, as shown in Figure 3. Remove the cover of the case using a
7/16” hex head screwdriver. When finished, replace the cover.
To increase the screen's fully extended (screen down) stop position:
1. Lower the screen to its current stop position.
2. Locate the red extension (down) thumbwheel located on the left
side of the screen tube. Turn the thumbwheel in the direction of
the (+) sign. If the power is on, the screen will drop incrementally
as the thumbwheel is turned.
Note: One complete turn of the thumbwheel will make
approximately a 3/4" change in the screen's stop position.
To decrease the screen extension:
1. Lower the screen until it is extended about halfway down.
2. Locate the red extension (down) thumbwheel located on the left
side of the screen tube. Turn the thumbwheel in the direction of
the (-) sign.
Note: One complete turn of the thumbwheel will make
approximately a 3/4" change in the screen's stop position.
3. Activate the screen in the down direction until it reaches the
newly reduced stop position. Repeat this procedure until the
desired stop position is reached.
Once you have made the adjustment, whenever you lower the screen, it will
automatically stop at the new position.
Note: It is recommended that you make a note of any changes made to the
factory preset.
