Maintenance & Care
Cleaning the chuck
Because of the additional protection
washer (see right), not much dirt is
usually entering the handpiece. In
the process of time, some dirt might
collect itself within the handpiece,
and might affect its functions.
Therefore the chuck has to be
cleaned monthly.
Dismantle the chuck:
Screw off the top of the handpiece
with the tool 5343:
Now clean the inside of the
handpiece and the top with a dry
brush.
For opening the chuck, push the
button forward.
Set the tool 5300 on
the axle and hold it
tight. Now use the
front of tool 5343 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.
Cleaning the chuck
Soak the chuck in spirit or a special
cleaning liquid for tools. Clean the
slits and the hole of the chuck with
a dry scrubber or brush. 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. Now dab off the oil til
your finger is only covered with a
very thin film of oil. Now move the
chuck in between your thumb and
pointer. There should be only a very
thin film of oil left on the chuck.
Please act according to the saying:
Less is more!
