The screen surface travel is stopped automatically in the fully opened and closed positions by limit switches that are

properly adjusted at the factory. The screen should not be adjusted for more or less drop.

Should the picture surface get out of adjustment and it be necessary to adjust picture surface drop, proceed in the follow-

ing manner.

NOTE: Use a small flat screwdriver or allen wrench to make adjustments. See Figure 3.

CAUTION! When adjusting limit switches and testing, be prepared to stop screen quickly as serious damage may

occur.

More Screen Drop

1. Place operating switch in

Down" position.

2. When the screen stops, turn the white "Down" limit knob one-quarter turn counter-clockwise. Test by raising picture

surface approximately two feet, then lower again. Repeat until proper screen drop has been attained.

Less Screen Drop

1. Raise picture surface approximately two feet above desired level.

2. Place operating switch in "Off" position.

3. Turn the white "Down" limit knob one-quarter turn clockwise. Test by lowering screen until it stops. Repeat until

proper screen drop has been attained.

NOTE: The yellow "Up" adjustment knob controls where fabric stops in the case. Do not adjust bottom slat to come

in contact with the fabric on roller.
