The film skates should sit close rather
uniformly in the whole film path.
If the skate lifting is actuated (reverse
running) the film skates should lift up at
the top by about 0.5 mm.

Regulating the film pressure skates
Because the film pressure skates will grind-in by the time, you have to check
regularly the skate sit. If necessary regulate it.
Skate distance
• skate distance too far: - The engagement of the sprocket teeth in the
perforation can no longer be assured.
- Film draws over the teeth.
- The loop becomes too small.
- Film breaks.
• skate distance too close: - The sliding friction increases.
- The drive will be stressed.
- The film will be damaged.
Skate height
1. For this purpose two film layers 16 mm respective 35 mm are put into the film
gate and the film skate 16 mm or 35 mm is closed.
By loosening the counter set screw , the skate can be adjusted in its height.
After adjusting fasten screw again.
2. The horizontal distance of the skate to the film gate can be corrected after
loosening the Allen screws on the lower and upper adjusting element .
Evenly shift the adjusting elements. After adjusting fasten Allen screws again.
3. Check the adjustments by running a film. If necessary adjust again.
