the motor blocks during the treatment.
Never use the power supply unit (Meanwell GS40A12-P1J),
if it is open, if the mains cable/socket is damaged, or if it has
a damaged housing. Warning: Electric shock may occur.
Only work with recharging units recommended by hadewe.
Charging units of other manufacturers may use a power
output, which might be too hight, and would lead to damage
the unit, or even cause it to burn. You will find the
description of permitted charging units under the technical
data.

Safety instructions
Regularly check the mechanical safety of the unit (look for
damages to the housing or mains cable for example).
Always follow the operating instructions.
Do not carry out any repairs, modifications or maintenance
work yourself. This is only to be accomplished by an
authorized specialist. The mains cable may also only be
changed by the manufacturer, or an authorized specialist.
Never remove the housing, 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 guarantee/warranty,
and any other liabilities of the manufacturer.
To prevent any possible safety risks make sure you always
use only original hadewe accumulators. Never disassemble
the accumulators in any way.
In case the unit was exposed to impact of any kind, it had to
be checked, that the accumulators have not sustained
damage. Switch off the unit at the transport safety device.
Remove the accumulators from the unit (see page 10), and
check the accumulators for damage according to the
following list:

Safety instructions
Damaged Accumulators:
A damaged accumulator can be identified by:
damaged or deformed housing of the accumulator
tarnished spots on the metal parts of the batteries
melting points
heating accumulators when the unit is switched off
leaking of the batteries
The unit is never to be used with damaged accumulators.
A damaged accumulator or a unit with damaged
accumulators is to be stored in a non-burning, non-
conducting (electricity) vessel. If you have to move the unit
with damaged accumulators, you have to remove the
accumulators first (see page 10). A damaged accumu-lator
may never be shipped. It is only to be transported in a
ireproof, non-conducting container, and under supervision.
With a damaged accumulator it is possible that battery acid
is leaking out. Therefore make sure to only touch it wearing
protective gloves. Should the battery acid ever get in contact
with human skin, rinse with lots of water for at least 15
minutes. Should the battery acid ever get in contact with the
human eye, also rinse the eyelid with lots of water for at
least 15 minutes.

Before the use
Please read through the instructions
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
The control unit can be set up in a
cabinet, or can be used as a
portable unit (e.g. in a carry case). It
is suitable for the following scopes:
Footcare/Manicure: Milling,
trimming and polishing. (Attention:
Additional spray or suction might
have to be in operation during foot
care in your country).
Dental technique / -laboratory:
Milling-, trimming and polishing
work at plaster casts and models
(Do not use this unit for dentist
purposes, i.e. working directly on
the patient).
Industry: Grinding, milling and
polishing works.
Installation site / location
The installation of the workroom
must correspond to any regulations
according to your country laws. Set
up the control unit, so that the
ventilation slits are not covered or
blocked, and the exhaust air can
escape well.
The drill and the charging unit may
only be operated in confined
spaces. Temperature rising of the
housing is normal during operation.
Although the unit should never be
covered, nor be located near
heating devices or in direct sun
impact.

12
Before the use
Fully charge the unit before its first
use. Read the instructions in the
following chapter on how to
proceed.
Before first use
Before the first start you have to
turn the main switch from 0 to 1 with
a coin or a screwdriver.
Because of safety reasons you
have to turn the transport safety
switch from 1 to 0 for longer
transportations and shipment.
This switch interrupts the accu from
the control unit.

13
Maintenance & Care
Accumulators
The unit is powered by high quality
Lithium Iron Phosphate
accumulators. These accumulators
have a long life span and are very
safe. Thermal runaway is not
possible with these accumulators.
Accumulator running time
With fully charged accumulators
and a speed of 22.000 rpm in empty
running this unit has an operating
time of approximately 10 hours.
Charging display
When switching the unit on, the
number of bars in the display will
show you the current state of
charge of the accumulators:
10 bars = fully charged
1 bar = almost empty
Charging process
Only use charging device, which
have been approved by hadewe.
Never use any charging units,
which are not explicitly listed in the
technical data section at the end of
this manual. Charging units of other
manufacturers may damage the unit
by giving out too much power, and
may even cause the unit to burn.
To charge the unit, connect the
charging unit to the charging socket
at back of the unit, and connect the
plug to mains. During the charging
operation you will see a moving line
in the display. Once the
accumulators are fully charged, the
display will show the word “FULL”. If
the accumulators are empty, the
charging time should take approx.
2 hours.
Working with the unit is possible
during the charging process, but the
charging of the unit will take longer
time then. Should the unit be
completely empty, the accumulators
will have to be charged for at least 5
minutes, before the unit can be
switched on again.
Warning LED
If the remaining charge of the unit is
10% or less, the LED at the front of
the unit will start to blink.
Warning signal (acoustic)
As with all kinds of accumulators a
complete discharge of them will
damage the cells. To prevent this,
the unit will alert the user with a
loud warning sound as soon as a
deep discharge is imminent. You
will now have approximately 3
weeks to re-charge the unit to
prevent the cells from being
damaged.
In case you cannot recharge the
unit, and still want to turn of the
warning signal, you would have to
remove the accumulators by a
professional (see “change
accumulators”). Attention: Removed
accumulators are still discharging
themselves. Charge these
accumulators as soon as possible.

14
Maintenance & Care
Change accumulators
The plug has to be removed from
the connected charging unit. Switch
the unit off, and make sure that the
handpiece is secured in a way,
where it cannot cause damage or
injury in case of an unintended start
of the drill. Unscrew the 2 screws at
the bottom of the unit, and then
remove the unit’s upper housing.
Now remove the accumulators and
carefully unplug it from the
electronic board. Insert the new
accumulators and connect them to
the electronic board. Screw the
upper housing on again.
Clamping the tool/ bur
The handpiece is equipped with a
chuck, which can hold all burs with
a diameter of 2,35 mm (this is the
diameter usually used for tools in
podiatry). To open the chuck, push
the spanner forward with your
thumb and leave it there. Now insert
the tool as far as possible. Pull back
the knob and the tool will be firmly
clamped.
For security reasons,
only change the tool, if
the handpiece is turned
off.
Setting up the speed
Hold the handpiece (incl. tool) in
your hand or store it in the
handpiece holder attached to the
side of the control unit.
Switch on the unit with button (6).
Now you can also set the speed
with buttons (3) and (4), and choose
its direction of rotation with button
(5). In reverse running the LED (2)
will be on.

15
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 tool 5343:
Now clean the inside of the
handpiece and the top with a dry
brush.
For opening the chuck, push the
button forward.
Set the tool 5300 on
the axle and hold it
tight. Now use the
front of tool 5343 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 spirit 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 afterwards.
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!

16
Handling details
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 put any wet burs or
instruments into the
handpiece. Its moisture
could damage the interior parts of
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.
Always working with
maximum 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.
