What?
Any unusual rattling noises can be eliminated by
regreasing. The sleeve (1) moves downwards or
upwards with the toothed spindle (2) in the fixed
driven sleeve (3) during drill feed. The noises are
caused by the necessary clearance between the
two toothings of the sleeve and spindle. The grease
in the delivery condition may have been used up.

Img.6-2:
Regreasing is carried out from above via the
spindle drive. Apply grease at the visible toothed
area of the spindle. It is recommended to use a
grease which can remain permanently inside the
toothing. The grease "Staburag NBU 30 PTM" from
Klüber is recommended and has proved to be a
successful assembly grease for clearance fits.
