M 1. Open the collet chuck with the "Release tool" function of DentalCNC.
M 2. Open the working chamber door and remove the tool from the spin-
dle if necessary.

hand insert the measuring pin through the knurled nut into the collet
chuck and keep holding it.
M 4. Unscrew the collet chuck with the knurled nut.
M 5. Remove the measuring pin from the collet chuck. Then put it aside
within reach together with the knurled nut.
M 6. Clean the inner cone of the spindle with the cleaning cone of the
service set.
M 7. Clean the collet chuck with the brush of the service set. Make sure
that the 3 buffers in the collet chuck do not fall out during cleaning.
Damaging of the spindle when using the wrong or wrongly applied
grease
If you use grease that is unsuitable for the spindle or if grease gets into the
longitudinal slots of the collet chuck, the spindle can get damaged.
Make sure that no grease gets into the longitudinal slots of the collet
h
chuck.
Only use a very small, about pinhead-size amount of the grease.
h
Only use the provided collet grease of the service set.

M 10. Insert the measuring pin into the collet chuck with one hand and
keep holding it. Screw the collet chuck with the knurled nut in your
other hand tightly into the spindle.
In any case, turn the knurled nut as far as it goes so that the collet chuck sits
tightly in the spindle. Otherwise rotational imperfections can occur during
operation which worsens your processing results.
