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 circum-
stances). 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.
Working with high pressure
will not improve the out-
come 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.
Always working with maxi-
mum speed might have a
similar effect. Please make
sure that the speed setting you use
is according to the work you are
doing and the instruments you are
working with.
In case of sending the de-
vice by mail remove the dust
filter before.
Only suck up dust or milling
waste, never suck up larger
particles such as small bits
of cotton wool as this may be get
caught in the handpiece and lead to
blockages.
