Foreword
The Auroria foot care unit was produced according to strict quality criteria and uses the
latest technology in its design. The images in this manual may vary slightly from the
product you have bought as we are constantly developing our products.
This user manual includes a detailed description and explanation of how to use the
Auroria unit. If you have any questions or suggestions you can contact us by telephone
or email.
This user manual belongs with the Auroria unit. Keep it somewhere safe. If you give
this product to someone else please include this document as it includes important
information on how to correctly use the product.
Short description of functions
The Auroria is a device for the treatment of callus and nails. The handpiece is compati-
ble with rotating tools such as diamond polishers, steel cutters and ceramic cutters.
These can reach at speeds up to 40,000 rpm and therefore provide an efficient way of
removing tissue. The direction of rotation can be changed by pressing a button. The
integrated filtered suction function effectively sucks up any dust particles. The rotation
speed and suction function can be adjusted using the keyboard. The device display will
notify you when the filter needs to be changed and when the device is due for inspec-
tion

Troubleshooting
Handpiece vibrates, is very noisy
and/ or becomes warm in the
front part
Use of bent burs/ tools ÆUse a dif-
ferent bur/ tool to test this. The
bur/tool itself can be tested with the
hadewe Bur Shaft Tester (Art. No.
(4990) to see if it is bent).
Maximum allowed speed of the tool
was exceeded, which caused a
stronger vibration Æpay attention to
the tool (i.g. bur, capper and instru-
ment) manufacturers handling de-
tails.
Bur/tool can be inserted only with
difficulty, or not at all.
Use of bent burs/ tools ÆUse a dif-
ferent bur/ tool to test this. The
bur/tool itself can be tested with the
hadewe Bur Shaft Tester (Art. No.
4990) to see, if it is bent).

faulty ÆPull out the socket of the
foot switch to see if this is the cause
Pull out the mains plug to reset the
device
The unit shows different sound lev-
els at different sites of use
The sound level varies according to
the surroundings of the unit. If you
set up the unit directly in front of a
wall, the sound is reflected stronger,
as if it would, while standing further
away from a wall.
Handpiece motor stutters shortly
(appr. 1 sec) when turning unit on
In very rare cases this effect did
appear. It will not harm or damage
the device.
Suction function doesn't work
The suction motor will turn off automati-
cally if it overheats. Let the device
cool down before using it again.
Send the device off for inspection if
this occurs repeatedly.

22
Handling instructions
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.
7
Safety Instructions
The light on the handpiece is for lighting the area being
treated. Do not look directly into the light.
Never use the suction to vacuum any liquids (or air/water fog
which contains particles of liquids).
When the device is brought out of standby mode it will run
with the rotation speed and suction power used last. Take
care to not start the mill at an overly high rotation speed.
Select the required rotation speed before changing the mill-
ing tool.
Always follow the operating instructions.
Do not carry out any repairs, modifications or maintenance
work yourself. This is only to be accomplished by an author-
ized specialist. The mains cable may also only be changed
by the manufacturer, or an authorized specialist. Mainte-
nance records may be supplied to repair workshops and
trained technicians upon request. Never remove the hous-
ing, especially not while the equipment is plugged into the
socket, since some components are under electric voltage.
Any unauthorized or improper handling (e.g. trying to repair
the unit) of the equipment will immediately nullify the guaran-
tee/warranty, and any other liabilities of the manufacturer.
This appliance can be used by children aged from 8 years
and above and persons with reduced physical, sensory or
mental capabilities or lack of experience and knowledge if
they have been given supervision or instruction concerning
use of the appliance in a safe way and understand the haz-
ards involved.

Cleaning and disinfection
Cleaning and disinfection
The device is designed to be compatible with rotating in-
struments which do not penetrate the skin or mucosal or
inadvertently may still cause injuries. For this application please
adhere to the cleaning and disinfection instructions provided be-
low.
After every treatment please carry out the following steps:
Remove the rotating tool (e.g. bur, capper, etc.) first.
Then handle the tool according to the instructions of it`s manufac-
turer.
Remove tissue remains by wiping off the unit with a mildly mois-
tened paper cloth. Afterwards clean all surfaces with disinfection
cloth (e.g. Mikrozid AF Tücher of Schülke and Mayr) There is no
limit to the number of times this device can be cleaned and disin-
fected during its recommended lifespan.
21
Handling instructions
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
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 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.
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.

carefully before using the unit and
carefully note the safety advice.
Always keep this manual accessible
to any users of the drill.
Area of application
This device should only be used by
people who have completed a foot-
care qualification. Before use the
operator should make themselves
familiar with the device by reading
this manual or being instructed by
another. The device must only be
used in closed spaces. It may be
used in hospitals, in a commercial
environment or in homes. The de-
vice is not intended for use in oper-
ating rooms.
The control unit can be set up in a
cabinet, or can be used as a porta-
ble unit (i.g. in a carry case). It is
suitable for the following scopes:
•Footcare: Milling, trimming and
polishing. (Attention: The suction
must be in operation during foot
care).
•Manicure: Grinding, milling and
polishing works.
The devise is determined of
operating rotating instruments,
which will not penetrate the skin
or murcous membrane if used
appropriate, but could evoke
damages accidently.

Maintenance & Care
Cleaning the chuck
Because of the additional protection
washer (see right), not much dirt is
usually entering the handpiece. In
the process of time, some dirt might
collect itself within the handpiece,
and might affect its functions.
Therefore the chuck has to be
cleaned monthly.
Dismantle the chuck:
Screw off the top of the handpiece
with the spanner shown in the pic-
ture:
Now clean the inside of the hand-
piece and the top with a dry brush.
For opening the chuck, push the
button forward.
Set the screw spanner (wrench) on
the axle and hold it tight. Now use
the front of the second spanner to
unscrew the chuck.
To assemble the chuck follow the
steps in reverse order. Make sure
that the chuck is opened during the
assembly (the handpiece button
must be in forward position), and is
firmly applied afterwards.
Cleaning the chuck
Soak the chuck in ethyl alcohol or a
special cleaning liquid for tools.
Clean the slits and the hole of the
chuck with a dry scrubber or brush.
Rinse the chuck very well, and
make sure you let it dry well after-
wards.
Cover your index finger with a very
little amount (just a drop) of oil and
rub in between your thumb and
index finger. Now dab off the oil til
your finger is only covered with a
very thin film of oil. Now move the
chuck in between your thumb and
pointer. There should be only a very
thin film of oil left on the chuck.
Please act according to the saying:
Less is more!

Use
Operation
In the following section the order in
which you should use the device is
described. Additionally the individu-
al steps will be explained in detail.
Read the complete manual before
use.
After connecting the device to the
power press the standby button (14)
to make it start rotating. Use the (2)
and (3) buttons to select a rotation
speed. Manufacturers often provide
recommendations for optimal rota-
tion speeds. However it is important
that you never exceed the maxi-
mum recommended rotation speed.
You can now choose a rotation
direction using the button (4). The
most commonly used direction is
clockwise. Most milling instrument
(steel instruments with steel cutters)
are optimised for clockwise use.
The rotation direction is irrelevant
for diamond cutters and high-grade
corundum sanders in terms of effi-
ciency. Working anti-clockwise can
be beneficial if, for example, the
dust obscures your field of vision
when working clockwise.
Using buttons (7) and (8) you can
adjust the intensity of the suction.
Frequently used rotation speeds
and suction power settings can be
saved. First select the desired rota-
tion speed and suction power. Save
these settings by pressing the M1
button for 4 seconds. To use your
custom settings simply press M1.

Suction
Switch on the suction with button
(8). The suction output can be regu-
lated in 5 levels. You will see the
selected level in the display. Level 0
would mean that the suction is
turned off.
In case the suction motor over-
heats, the unit will switch off auto-
matically. Leave the unit to cool off
for a while before starting it again.
Should the same failure appear
again, please return the unit to your
supplier for inspection.
Exchange the filter bag
When changing the filter it
is advisable to wear a face
mask conforming to EN
14683 type IIR or EN 149 FFP 2.
Only operate the unit with a suction
filter assembled. Control the bag
after every 10 operating hours. Ex-
change a full filter bag immediately.
A filter should be exchanged at
least after 50 operating hours.
At first, unfold the paper of the mi-
cro filter (Art. No. 5179) bag and
push your finger into the opening in
the front.
Pull out the lid of the dust chamber
and remove the old filter.
Hold the filter in the middle to pre-
vend it from bending and sliding off
(see picture below). Therefore you
avoid it from coming off again.
Exchange control unit filter
This filter (Art. No. 3752) has to be
exchanged after every 200 operat-
ing hours. Remove the old filter and
place the new one in its holder (see
picture).
