Handling Instructions & Troubleshooting
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.
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 or even devastation 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.
Troubleshooting
When the motor stutters or does
not run
…
Possible cause: worn carbons
In this the case we suggest to
send us the handpiece for
maintenance works.
If the handpiece becomes hot
…
In case the handpiece should
become hot or the noise level
extraordinary loud, apparently
the ball bearings of the front part
of the handpiece are worn out.
In this the case we suggest to
send us the handpiece for
maintenance works.
