Maintenance & Care
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:
Rinse the chuck very well, and
make sure you let it dry well
afterwards. Cover your index finger
with a very little amount (just a
drop) of oil and rub in between your
thumb and index finger. Dab off the
oil until your fingers is only covered
with a very thin film of oil. Now
move the chuck in between your
thumb and index finger. There
should be only a very thin film of oil
left on the chuck. Please act
according to the saying: Less is
more.
