Handling instructions
Never put the handpiece
into any kind of liquid, and
never oil or grease the
handpiece. Clean its surface with a
damped cloth. Pay attention, that no
moisture
or liquid enters the
handpiece. Never use spray dis-
infection.
Never put any wet burs or
instruments
into the
handpiece. Its moisture
could damage the interior parts of
the handpiece.
Any materials used by
hadewe prevend a formation
of rust. In cases in which a
rust infestation was found within the
handpiece, thorough inspections
and examinations always have
proved that the rust had a foreign
origin (which was usually caused by
the
tools used in these
circumstances).
Even in high-grade steel
instruments of well known
manufacturers, formation of
rust can appear, e.g., through
wrong treatment with chemical
cleaning and disinfection liquids.
This extraneous rost affects internal
parts of the handpiece in form of
rust bloom and causes pitting.
Therefore, when you not working
with the handpiece, always remove
the bur/ tool from it.
Always make sure that you
do not let the handpiece fall
down or exposes it to any
shocks. The ballbearings and the
motor could be damaged by this.
Only work with tools, which
are flawless.
Do not work with tools which
-
are bent or out of balance
- whose shaft is worn out or
- are rusty.
Working with faulty tools will
cause a stronger vibration of
the handpiece. A damage of
the ball bearings, clamping tech-
nique or motor could be the conse-
quence.
