Panchromatic Bell & Howell 606 Gaumont (H) User Manual
If there is a noticeable flicker of the light on the screen, turn
the speed control Fig 1 14) in an anti-clockwise direction until
the light is steady. Sharp definition of the edge of the light area
on the screen indicates approximate focus of the lens.
To focus the lens, loosen the lens locking screw (Fig 1 12),
slide the lens backwards or forwards for rough focus and to
make fine adjustments rotate the lens by its knurled front
edge. Lock the lens in position. Return the clutch to the STOP
position and switch off the lamp and motor.
Threading
1. Place the empty take up spool on the spindle of the lower
arm (Fig 1 11) with the spool centre hole slits towards the
take up arm. The spool must click firmly over the spring of
the spool spindle. Place the full spool on the upper feed
arm spindle (Fig 1 7) in the same way.
2. Unwind about 18” of film from the top spool. The film
should feed from the lower front of the spool with the dull
side out and the sprocket holes nearest you as you thread
the projector.
3. Open the sprocket Guards Fig (1 10) by pressing towards
the lens mount, and open the film gate by raising the gate
operating lever (Fig 1 8)
4. Pass the film under the top sprocket and ensure the
perforations fit over the sprocket teeth. Close the sprocket
guard. Next form the upper loop as shown in Fig 3
5. Lead the film through the channel behind the lens, making
sure it is fully located in the channel. Close the film gate
by lowering the lever (Fig 1 8). The gate will only close
properly when the rewind lever (Fig 1 6) is in the RUN
position
6. Form the second loop before passing the film over the
lower socket and close the sprocket guard
