Handling Instructions
Always deposit the handpiece
with the top downwards. There-
fore 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 dis-infection.
Never put any wet burs or in-
struments 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 examina-
tions 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 in-
struments of well known manu-
facturers, formation of rust can
appear, e.g., through wrong treat-
ment 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, al-
ways 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.
Always working with maximum
speed might have a similar
effect. Please make sure that
the speed setting you use is accord-
ing to the work you are doing and
the instruments you are working
with.
