1. ABOUT THE USER MANUAL
1.1 Availability
This user manual is supplied with each device and can also be ordered retrospectively.
1.2 Legal guidelines
The information in this manual corresponded to the most recent status at the close of editing. The
illustrations and descriptions cannot be used as grounds for any claims relating to devices that
have already been delivered. Timken accepts no liability for any damage or malfunctions if the
device or accessories have been modied or used in an incorrect manner.
1.3 Original user manual
The original user manual is taken to be a user manual in the Dutch language. A user manual in
another language is to be taken as a translation of the original user manual.
FOREWORD
The Timken G2 induction heating devices 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.
In order to ensure durability in demanding industrial operation, the devices are extremely robust
and reliable.

2.2 Description of potential hazards
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 eld
Be aware that you are working with an appliance that generates electromagnetic
elds. Keep a distance of 1 metre from the unit after switching on.
These elds can be harmful for persons with active medical aids such as
pacemakers.
These elds 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 eld may inuence
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 eld 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.
Furthermore, it cannot be ruled out that the electromagnetic elds could cause
damage to electronic and magnetic data media. Keep such equipment away from
the induction heater.

8
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 superuous objects
from the immediate vicinity of the unit.
• Position any cables, including the power supply ones, as low as possible to
minimize 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 Timken 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.

2.3 Safety measures to be taken
• 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 tted with the proper plug. This must be tted by a qualied electrician.
• Never use or store an induction heater in a damp environment.
• Only use Timken 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 yoke or component.
• Never use a metal strap to support workpieces or suspend them in the magnetic eld. High
currents could start running through the strap, causing it to heat up.
• Do not hold metal objects near yoke and poles.
• Whilst heating, observe a minimum distance of 1 metre (3.3 ft) from the heater.
• Never remove the induction yoke during heating.
• Do not modify the heater. Never use home-made yokes.
• Always check that the induction yoke 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 yoke.
• In the event that smoke or vapor is emitted from the workpiece during heating, ensure that
there is extraction or sucient ventilation in the workshop. Do not inhale vapours or fumes!
Hazard area
The hazard area of the heating device can represent a danger of death.
WARNING!
Failure to observe the following warnings could create a risk of death
or serious injury.
• Danger of heart stoppage in persons tted with a pacemaker due to the strong
electromagnetic eld. Ensure that persons tted with a pacemaker remain outside the hazard
area of the heating device. Erect barriers and attach clearly visible warning signs, Figure 1.
WARNING!
Failure to observe the following warnings could create a risk of death
or serious injury.
• Danger of death for persons with articial heart valves made from metal, hazard of severe
burns due to heating of implants by the electromagnetic eld, see chapter 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.

2.4 Safety provisions
• The electronic systems switch o automatically if the ambient temperature rises
above 70ºC (158º F).
• 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 eld. At a distance of 1 metre, the magnetic
eld has been reduced to such an extent that it is below the applicable standard
of 0.5mT.
WARNING!
Failure to observe the following warnings could create a risk of death
or serious injury.
• 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 eld may inuence the
proper function of such medical aids.
• For this reason, persons with passive implants are recommended not to enter the
immediate vicinity of the induction heater when it is in operation.
