Handling Instructions
Always
deposit
the
handpiece with the top
downwards. Therefore, you
can avoid liquid from entering the
handpiece.
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
disinfection.
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 prevent 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 rust 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 ball bearings 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
technique or motor could be the
consequence.
Working with high pressure
will not improve the outcome
of your work, since the
motor will even be slowed down. A
second
disadvantage
is
the
stronger impact on the ball bearings
and the motor, which will shorten
their life span in the long run.
