• Remove the film from its can and bag.
• Place the film roll on the rear spindle. Check that the core drive
pin on the spindle is not caught on one of the core ribs or the roll
will not seat properly. Secure the spindle-lock.
• Thread two feet of film, making sure it passes outside the top gui-
ding rollers.
• Insert the film between the pinch rollers and sprockets making
sure the perforations engage with the sprocket teeth.
• Turn the upper and lower pinch rollers clockwise, to close them.
• Slide the film in the slot of the take-up core. Rotate this core three
or four turns.
• Check that the film is firmly attached and positioned correctly
around the sprocket wheels.
• Close the door, and fasten the door locks by turning them upward.
If you cannot close the film door, it means that you have forgotten
to close one or both pinch rollers.
• The remainder of the procedure can be performed in daylight.
