Method Of Operation - ( refer to Layout picture above )

First ensure that the film indicator window registers zero. 0 is in the window. This is accomplished by releasing the transport mechanism by pressing the mechanism release button in the direction of the arrow and releasing and rotating the transport knob clockwise. This operation must be repeated as each number appears in the window until the 0 has registered.

Having ensured the 0 is present in the film indictor window, the spring loaded cover release catch is pushed to the right and the cover which is spring tensioned will open.

Swing the cover back on its hinge to its fullest extent. Pull the film transport knob outwards i.e away from the body and it will then be possible to lift out the spool body.

Remove the sealing strip from the 120 film and place spool on to the supply spool spigots, one spigot is hinged to facilitate this.

The film is placed in position so that the outside of the backing paper is in contact with the spool tensioning spring plate and that the film is being unwound in the direction indicated by the arrow on the side of the spool body.

The backing paper is then led over the roller and along the face of the spool body over the other roller and fed into the takeup spool, which is positioned on the take up spool spigots. Fit the leading edge of the backing paper into the widest slot of the take up spool and rotate the film setting thumb wheel in the direction of the arrow on the side of the spool body until the arrow mark or line on the backing paper is in position in the window marked by the Red arrow on the base of the spool body. Refer to picture below.

Rotate the film transport knob in a clockwise direction until the mechanism locks. The no. 1 should then be visible in the film indicator window and ensures that the film is in position for the first exposure.

After the film has has been exposed, release the mechanism by operating the mechanism release button as before and rotate the film transport knob until it locks. The no. 2 will now be visible in the film indicator window, signifying that the film is in position for the second exposure.

This operation is repeated until the fuill number of frames have been exposed i.e 8 or 12 according to type. After the last exposure, the mechanism release button is operated again and the film transport knob rotated unti,it again locks when the no. 0 appears in the film indicator window.

By the rotation of the film transport knob after the last exposure until the no. 0 appears in the film transoprt window, the film has been wound off and is ready for removal from the Film Holder.

The cover is opened as before by pushing the cover release catch, the film transport knob is pulled out from the body and the spool body removed.

Press the hinge flap of the takeup spool and remove the film from the the spool body and secure the film it its rolled up position by the sticky paper provided.
