*Thread the film as illustrated. Engage the film on the intermittent sprocket (Item 9), and check for correct framing at the framing aperture (Item 12). When correct, close the gate by firmly holding the gate opening lever and tripping the gate release (Item 8). Walk the lever back by hand to prevent the gate from slamming into the trap with excessive force. Form loops above and below the gate as illustrated, and close the pad roller assemblies (Item 2, 5).

*Turn the mechanism by hand to advance a few frames of film. Run fingers over each sprocket (Items 1, 6, 9) to ensure that the sprocket teeth are centered in the film perforations, and the film is centered on the sprockets. Double check the position of the film in the framing aperture (Item 12). A correct frame image in the framing aperture ensures correct frame positioning in the picture aperture (Item 11). The framing knob (Item 7) can be used to correct misframes, but doing so reduces the framing range during playback. It is advisable to open the gate and rethread with the framing knob in its center position.

*Thread the soundhead as instructed in the soundhead manual. A slight degree of film tension is required above the feed sprocket (Item 1) and below the soundhead. This prevents the film from snapping on motor start.
