1. Select the size of star guide appropriate for the job.
Star guides may be trimmed by cutting the individual
vanes with scissors.
2. Lay out two or three star guides next to their C-rings.

3. Spread the C-ring open just enough to slip it over the
hub of the star guide. Align the C-ring gap with the
gap in the star guide. Press the C-ring into the
grooved portion of the hub. Repeat with the second
C-Ring for the opposite side of the hub.
4. Spread the star guide and C-rings together and slide
over the camera head, or around the cable and up
from the camera base, to the desired position on
the spring and release.
5. Pre-stressing the vanes of the star-guide will help
make them more flexible in use. Bend each vane gen-
tly back and forth several times to pre-stress them.

6. Once the star guide is installed, it will help to prevent
loss if you adjust the C-ring so that the gap is at
least 90 degrees from the star guide's gap.

7. Removing Star Guides: Slide the end of a flat-
tipped screwdriver between the C-ring and the base
of the vane. Pry or snap the C-ring off. Repeat for the
second C-ring and slide the rings and the star guide
off the cable.
Installing Ball Guides
Ball-type centering guides use two retaining rings that
hold the guide in place on the spring.
Figure 16 – Camera With Ball Guide In Use
To unlock the retaining rings, pull them outward with the
tip of a flat-tipped screwdriver. You will then be able to
slide the ball guide over the camera head and position it.
Lock the rings by pressing them in once the guide is in
position.
