There are 5 main "novice" errors that I have encountered in the 40 screens equipped with Kinoton equipment that we directly service.
1. Since the skate and runners are delrin and nylon, and wear progressively, novice operators aren't aware when the skate needs slight adjustment in tension or height to maintain classic "Kinoton" stability. Lack of qualified operator, means the service company needs to be on site quarterly to keep this up. Worse, if the skate gets replaced by a notice operator, they might not reset the tension/height, and ultimately ruin the part in record time.
2. Gate temperture is critical given the low melting temp of the runners/skates. During a lamp change, it is important to focus the lamp carefully to avoid melted parts.
3. A misthread in the gate, that results in a lost lower loop can literally pull the loop stabilization roller pair into the skate, pushing it upward to the sprocket. If left unnoticed by a novice operator, rapid wear of the skate occurs.
4. Rough handling of the oil fill tube of the intermittent results in a small fracture of the tube where it is glued to the threaded base. This results in a slow leak that "appears to be seal failure" of the movement. ..and a big oily mess.
5. Novice operators, who thread out of frame frequently, operate the framing knob that slides the framing bushing on the shaft splines, and thereby shortening the lifespan of the bushing.
Any theatre that can maintain a projectionist for a reasonable length of time, and can learn the idiosyncrities of the Kinoton projector, will not have these issues. However, for the theatre that employs a round door policy of short tenure operators with diminishing knowledge passed from hand to hand, Kinoton equipment is not the best choice. In all likelihood, this same theatre would have low regard for screen image quality, and wouldn't consider the extra dough to purchase Kinoton in the first place.
