The method you use to raise and lower the screen depends on the type of
switch control device you have selected.
When you lower or retract the screen, it will stop at it s preset limit. If an
obstacle (such as a person or furniture) gets in the path of the screen as it
is lowered, you should use the switch control to stop the screen's motion; it
will not automatically stop if it hit s an obstacle.
The motor is designed to be used for short operations such as lowering the
screen in preparation for viewing. The motor is not designed for continuous
duty. If the motor operates continually for more than a few minutes, it may
automatically shut off to prevent damage from overheating. If the motor
occasionally needs to be run more than normal, for example during initial
setup and positioning, allow time for the motor to cool down.
In general, when the screen is not in use, you should store it in the fully
retracted position.
The extension and retraction limit switches have been preset at the factory.
In general, we advise you to avoid readjusting these switches.
In some cases, to enable proper alignment of the displayed image on the
screen, you may need to adjust the extension of the screen. If adjustment
to the extension is necessary, carefully follow these instructions.
12 Stewart Filmscreen Corporation
OPERATING THE SCREEN
Caution
Do not operate the motor when any of the following occurs:
The unit emits any smoke, heat, abnormal noise or
unusual odor.
The unit is damaged in some way, such as damage from
a water leak.
If any of these situations occur, call a qualified service person.
Caution
Improper adjustment of the limit switches can cause
irreparable damage to the screen itself, resulting in voiding the
factory warranty.
ADJUSTING THE SCREEN EXTENSION

Model A Electriscreen: Owner’s Manual 13
Modifying the extension of the screen
You can increase the extension of the screen up to 3" (7.6 cm) p ast the
factory preset stop, or you can decrease the extension by approximately
4-6" (10-15 cm) from the factory preset stop. Do not attempt to modify the
screen extension beyond these recommended amount s.
The limit switches are located on the lef t side of the screen roller tube inside
the case, as shown in Figure 11.
To increase the screen's fully extended (screen down) stop position:
1. Lower the screen to its current stop position.
2. Locate the white extension (down) limit switch located on the left
side of the screen tube. Use a screwdriver to turn the switch in a
counterclockwise direction. If the power is still on, the screen will
drop incrementally as the switch is turned.
Note: One complete turn of the switch will make approximately a
3/4" (2 cm) 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 white extension (down) limit switch located on the left
side of the screen tube. Use a screwdriver to turn the switch in a
clockwise direction.
Note: One complete turn of the switch will make approximately a
3/4" (2 cm) 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.

Warning!
The screen is fully retracted when the batten is flush with the
bottom of the case. Some of the larger unit s require the
batten to stop at approximately 1 1/2” (3.8 cm) from the bottom
of the case. Do not attempt adjustment s with the yellow
retraction (UP) limit switch that will further retract the screen.
Incorrect adjustment of the switch will cause severe screen
damage. Please consult the factory if you have any questions.

With reasonable care, you can expect many years of trouble-free use of
your Stewart projection screen.
We encourage you to keep your screen clean. To protect your screen when
it is not in use, store it in the fully retracted position.
Avoid getting any foreign material on the screen, as cleaning may prove
very difficult. It may not be possible to remove scratches, paint, ink, etc.
General maintenance
The screen surface on your screen is delicate. Special attention to these
instructions should be followed when cleaning.
A draftsman-style brush may be used to lightly whisk away any
loose dirt or dust particles. (This type of brush is usually
available at office supply stores.) Stewart Filmscreen has an
optional screen cleaning kit that cont ains the proper type of
brush. Contact your dealer if you would like to obtain this
cleaning kit.
Particles left on the screen when it is retracted into the case may
form an impression on the screen surface. Periodically wipe the
back of the screen with a clean damp cloth.
For tougher spots, use a solution of mild detergent and water .
Rub lightly using a sponge. Blot with a damp sponge to absorb
excess water. Residual water marks will evaporate within a few
minutes. Let the screen air dry completely before retracting.
Do not use any other cleaning materials on the screen. Contact the factory
if you have questions about removing dif ficult spots.
Replacement parts and service
No user-serviceable parts are contained within the unit. Cont act your dealer
or the factory if you require p art replacement or service.
