GENERALLY THE BEST POSITION for the operator to stand is near the center of the
spotlight, on the right hand side, although the angle of tilt and the size of porthole may alter the position
for the most convenient operation.
EACH OPERATOR will, after a few minutes of operation, generally develop his own
system and preferred position for operating the follow spot.
THE VERTICAL TILT LOCK LEVER located on the base assembly can be set to give
the required amount of friction on the spotlight to suit the individual operator.
THE LENS CARRIAGE FRICTION BRAKE is located on the outrider of the large lens
carriage and is preset at the factory for the most satisfactory operation. Individual requirements vary
and the brake can be adjusted to suit the operator. Remove the color boomerang, reach through the
color gel opening and loosen the locknut. Then adjust the screw on the friction brake until the desired
tension is applied to the large lens carriage. Tighten the locknut and replace the color boomerang.
THE COLOR BOOMERANG is equipped with six color filter discs containing the
following colors in order from rear to front:: (1) Amber, (2) Flesh Pink, (3) Daylight Blue, (4) Light Sky
Blue, (5) Primary Blue, (6) Light Red. Keep the darkest or most dense colors to the front of the
boomerang. A heat filter is mounted in a fixed position behind the boomerang to protect the gels.
THE SIX COLOR DISC LEVERS are mounted in the cover plate casting directly in
front of the aperture selector lever. To insert a color disc in the light beam, move the proper color disc
lever to the left as far as possible. To release a color disc, move the lever to the extreme right. Be sure
that the lever is always fully returned to the limit of its movement.
TO REMOVE A COLOR DISC ASSEMBLY, remove the knobs from the aperture
selector, masking shutter and fadeout levers. Remove the two end screws from the cover plate casting
and lift off the complete boomerang assembly. The two split rivets holding the color disc assembly can
now be removed and a new color disc assembly installed. Only the six above-mentioned color discs are
supplied with the boomerang; additional colors are available from theatrical supply dealers.
