Stewart Filmscreen Corp CM-1005 - Manual (Page 14)

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 its 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 hits 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.
