The induction heating devices HEATER20-BASIC, HEATER50-
BASIC, HEATER100-BASIC, HEATER150-BASIC and HEATER200-
BASIC give rapid, clean operation. Their high eciency level
allows energy-ecient heating and shorter mounting times.
This reduces the operating costs. The uniform, controlled
heating allows consistently good quality of mounting.
Operation is simple and user-friendly, the touch-sensitive
screen is oil-resistant, dustproof and waterproof.
When heating by induction is used, there is no need at
all to use oil – this gives particularly good environmental
compatibility. The scope of application is very extensive.
It is possible to heat the loose inner rings of cylindrical or
needle roller bearings as well as sealed and greased bearings.
Compared with previous models, further improvements have
been made in performance capacity and safety and the part to
be heated need no longer be of a minimum mass.
In order to ensure durability in demanding industrial
operation, the devices are extremely robust and reliable.

2. Safety, warnings and potential hazards
2.1 Explanation of the
pictograms

Schaeer Technologies 7
Warning! Voltage
Be aware that you are working with an
electrical appliance. On the mains side as
well as internally, voltages occur that can lead
to serious injury and death if used inexpertly
or improperly.
■Connect the unit to the power according to
the information on the rating plate.
■Before each use, check the power supply
cable for damage.
■Safe disconnection from the power supply
must be ensured at all times before
starting maintenance and repair work. This
can be achieved by removing the power
plug from the socket.
Warning! Electromagnetic field
Be aware that you are working with an
appliance that generates electromagnetic
fields. Keep a distance of 1 metre from the
unit when switching on.
These fields can be harmful for persons with
active medical aids such as heart pacemakers.
These fields can be harmful for persons
with passive medical aids such as joint
prostheses. The wearing of jewellery can also
result in injuries due to burns.
It is forbidden for persons with active medical
aids to be in the immediate vicinity of the
unit when it is in operation. The generated
electromagnetic field may influence the
proper function of such medical aids.
It is forbidden to wear jewellery when working
with the generator and inductors. There is
a risk of the jewellery being heated by the
electromagnetic field and resulting in injuries
due to burns.
For this reason, persons with passive
implants are recommended not to enter the
immediate vicinity of the induction heater
when it is in operation.
2.2 Description of
potential hazards

8Schaeer Technologies
Furthermore, it cannot be ruled out that the
electromagnetic fields could cause damage to
electronic and magnetic data media. Keep such
equipment away from the induction heater.
Caution! Tripping hazard
Limit the risk of injury due to tripping as
far as possible.
■Keep your place of work tidy. Remove any
loose and superfluous objects from the
immediate vicinity of the unit.
■Position any (power supply) cables as
low as possible to minimise the risk
of tripping.
Caution! Risk of burns
The workpiece becomes warm to very hot
during heating.
Parts of the unit may also become hot due
to contact with the workpiece or the heat
radiated by the workpiece.
Therefore always wear heat-resistant gloves
when handling workpieces in order to avoid
injury due to burns.
Caution! Risk of injury during lifting
A number of units in the Schaeer heater
range weigh more than 23 kg and may
therefore not be lifted by one person alone.
(see technical specs)
If a unit weighs more than 23 kg, lift it with
two persons or use suitable
lifting equipment.
Wear safety shoes to prevent injury from
unintentionally falling workpieces and/or
machine parts.

■The user must carefully read this manual and be familiar with
the safety standards in the work practice.
■Follow the instructions in the manual at all times.
■Check the connection voltage against the rating plate on
the unit. If the power cord does not have one, make sure
it is fitted with the proper plug. This must be fitted by a
qualified electrician.
■Never use or store an induction heater in a
damp environment.
■Only use Schaeer induction heaters indoors.
■If using a mobile version; always lock the castors when not
moving the device.
■If the heater is equipped with extendable horizontal supports,
always secure them with the appropriate locking pin, both in
the fully retracted and in the fully extended position.
■Use suitable lifting equipment according to the weight of
the ledge or component.
■Never use a metal strap to support workpieces or suspend
them in the magnetic field. High currents could start
running through the strap, causing it to heat up.
■Do not hold metal objects near ledge and poles.
■Whilst heating, observe a minimum distance of 1 metre
from the heater.
■Never remove the induction ledge during heating.
■Do not modify the heater. Never use home-made ledges.
■Always check that the induction ledge is positioned
correctly against the poles, so excessive vibration cannot
cause personal injury or damage to the device.
■Do not switch on the heater until the core is closed with
a ledge.
Hazard area
The hazard area of the heating device can represent a danger
of death.
DANGER!
Danger of heart stoppage in persons fitted with
a pacemaker due to the strong electromagnetic
field. Ensure that persons fitted with a
pacemaker remain outside the hazard area of
the heating device. Erect barriers and attach
clearly visible warning signs, Figure 1.
2.3 Safety measures
to be taken

10 Schaeer Technologies
■The electronic systems switch o automatically if the
ambient temperature rises above 70ºC.
■When heating in temperature mode, the heater switches o
if no 1°C temperature increase is measured during a time
pre-set by the manufacturer.
■The coil of the heater is equipped with a temperature
monitor. If the coil becomes too hot, the heating process is
switched o entirely.
■Models with a swivel arm are equipped with a safety
positioning cam.
An induction heater operates by means of a magnetic field.
At a distance of 1 metre, the magnetic field has been reduced to
such an extent that it is below the applicable standard of 0.5mT.
2.4 Safety provisions
WARNING!
Danger of death for persons with artificial
heart valves made from metal, hazard of
severe burns due to heating of implants by the
electromagnetic field, see chatper 2.2.
Ensure that persons with a ferromagnetic
implant remain outside the hazard area of the
heating device. Erect barriers and attach clearly
visible warning signs, Figure 1.
