Leica M3 - 27

The film cassette and the take -up spool must be pushed
fully home to ensure that the film lies properly between
the guides.
Check that the position of the film corresponds to that
shown in the diagram. The matt emulsion side must face
the lens and the focal plane shutter; the take-up spool
winds the film with the emulsion side out .
The
teeth of the transport sprocket should engage the
film perforations. If necessary , slowly work the transport
lever until the teeth engage .
Close the camera back , replace the base-plate , and lock,
thus making the camera light-tight.
The film counter automatically returns to its starting
position - two divisions before zero - when the take-up
spool is withdrawn . The length of film between the cas-
s ette and take-up spool is , of course , already fogged and
useless for taking pictures . It must therefore be advanced
in side the closed camera to bring a fresh , unexposed
portion of the film into position for shooting . Advance the
film by stroking the transport lever, and releasing the
shutter. Repeat these steps , and advance the film once
more so ' that the film counter indicates No . l. You are
now ready for the first exposure .
The correct functioning of the film transport can be recog-
nized by the fact that the red dots on the center shaft of
the rewind knob rotate while the film is advanced.
