Maintenance & Care
Rinse the chuck very well, and
make sure you let it dry well after-
wards. 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.
