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 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 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 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 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 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.
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 block-
ages.
