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.
