What? How?
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.6-5:
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.
