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 hand-
piece. Never use spray dis-
infection.
Never put any wet burs or
instruments into the hand-
piece. 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 manufac-
turers, 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 pit-
ting. Therefore, when you not work-
ing with the handpiece, always re-
move 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 outcome
of your work, since the mo-
tor will even be slowed down. A
second disadvantage is the strong-
er 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 and empty the spray
liquid tank before.
