Maintenance & Care
Chuck Cleaning
Because of the washer, very little
dirt might enter the handpiece. In
the curse of the time, dirt can ap-
pear and might interrupt the perfor-
mance of the handpiece. Therefore,
clean the chuck monthly.
How to remove the chuck
Screw off the top of the handpiece
with the spanner shown in the pic-
ture.
Now clean the inside of the hand-
piece and the top with the brush.
For opening the chuck, push the
button forward.
Set the screw spanner (wrench) on
the axle and hold it tight. Now use
the front of the second spanner to
unscrew the chuck.
To assemble the chuck, follow the
steps in reverse order. Make sure
that the chuck is opened during the
assembly (the handpiece button
must be in forward position) and is
firmly applied afterwards.
How to clean the chuck
Soak the chuck in ethyl alcohol or a
cleaning liquid for tools. Clean the
slits of the chuck with the brush.
Use the brush to remove all dirt
residues from the drill-hole of the
chuck:
