1. Loosen shutter clamp screws (item 7 in Figure 5-4) just enough that shutter can be
rotated on its shaft.
2. Turn projector by hand with motor flywheel until Ultramittent sprocket is in top position.
Sprocket should not move while flywheel is being turned.
3. Use sharp pencil. Carefully rest pencil point on Ultramittent casting, pointing to one
sprocket tooth.
4. Without moving pencil, turn projector by hand with motor flywheel until pencil is
pointing at third tooth from starting tooth of Ultramittent sprocket.
Hold motor flywheel to ensure that projector does not turn over while
rotating shutter.
5. Rotate shutter (item 4 in Figure 5-4)
by hand until crosshairs are centered in aperture.
Make certain shutter is not hitting anything.
6. Tighten shutter clamp screws (item 7 in Figure 5-4). Do not allow shutter to move on its
shaft after centering crosshairs.
7. Recheck shutter timing.
