NOTICE
Damaging of the spindle when using
the wrong grease or applying the
grease incorrectly
If you use unsuitable grease or if grease gets into
the longitudinal slots of the collet chuck, the
machine may get damaged.
Ensure that no grease gets into the lon-
gitudinal slots of the collet chuck.
Only use a very small, about pinhead-size
amount of the grease.
Only use the provided grease of the service
set.

Put a small amount of the collet grease on the
index finger and smear it with the thumb.
10.
Apply the smeared collet grease to the flanks of
the collet chuck.

Insert the measuring pin into the collet chuck
with one hand and keep holding it. Screw the col-
let chuck with the knurled nut in your other hand
tightly into the spindle.
Turn the knurled nut as far as you can so
that the collet chuck is properly seated in
the spindle. Otherwise rotational imper-
fections can occur during operation which
will worsen your processing results
12.
Remove the measuring pin from the collet chuck
and store it together with the other components
of the spindle service set.
