any other metallic object in, or, on your clothing before operating the
induction heater.
• Do not wear clothing that contains metallic rivets, waistband buttons,
pocket buttons or zips when operating the induction heater.
• The induction heater can heat these metallic objects very quickly and
cause serious burns or even ignite clothing.
• Always wear safety goggles when using the induction heater.
• Fumes and smoke from hot/burning adhesives are toxic. Wear an
appropriate dual filter (dust and fume) mask.
• Wear heat-resistant gloves when using the induction heater as it heats
metal very quickly. You can easily burn your hands and fingers when
trying to remove parts from hot metal surfaces.

Do not fit or remove a coil or rope coil with the induction heater plugged
into the mains.
• Before plugging in the induction heater, make sure that the outlet volt-
age supplied is compatible with the voltage marked on the label and
within 10% of the stated voltage. An outlet voltage incompatible with
that specified on the label can result in serious hazards and damage to
the induction heater.
• Ensure the induction heater is connected to a supply that is adequately
earthed. (Grounded)
• Do not use the induction heater in rain, moisture or immersed in water.
Exposing the induction heater to water or other liquids can cause an
electrical shock hazard.
• Do not use any attachments except for those supplied by Kamasa Tools,
use of non approved attachments may cause damage to the induction
heater and invalidate your warranty.
• Do not leave the induction heater plugged into the mains when not in
use.
• Damaged cords create electric shock hazards - Do not kink, bend, crush
or cut the mains electrical lead. Never carry the induction heater by the
mains electrical lead.
• Keep the lead away from heat, oil, sharp edges and/or moving parts.
• Do not use the induction heater if the lead is damaged. Leads cannot
be repaired, only replaced.
Do not use any attachment with damaged insulation, use of damaged
attachments can result in sparking and can cause a fire hazard. Use of
damaged attachments will invalidate the warranty.
INDUCTION HEATER SHOULD NOT BE USED CONTINUOUSLY FOR MORE
THAN 3 MINUTES ON ANY MATERIAL
The heat generated by the induction heater can cause paint/ aerosol cans,
or any other pressurised or sealed containers used for storing fuels or gas
to explode and their contents to ignite.
• Do not use an attachment if the insulation has been breached. If insula-
tion has been breached it can cause sparking when contacting with a
vehicle. This could be a fire hazard especially when working on, or near
fuel lines and/or fuel tanks.

• Use of damaged attachments will invalidate the warranty.
Do not use the induction heater without an attachment fitted. Ensure
attachment is securely located and locking screws are firmly tightened.
Do not use the induction heater for longer than the stated duty cycle:
THREE minutes on followed by THREE minutes o.
• The main circuit board has an overheat protection device, however the
attachments do not have overheat protection so should not be used for
more than THREE minutes of continued use.
• Please ensure that the cooling fan is running when the power switch is
operated, if the fan does not run DO NOT use the induction heater.
Do not attempt to create more than 4 coils, a minimum of 2 coils and a
maximum 3 to 4 coils is the optimum number needed for best operation.
The induction heater should not be left unattended whilst switched on.
• In order to cool eectively, and prolong the life of your induction heat-
er, always make sure that the vents of the induction heater are clean
and free of dust and debris so that the power unit has an unimpeded
flow of cooling air.
• Do not attempt to repair or service the induction heater. There are no
serviceable parts besides replacing the coil attachments.

OPERATION INSTRUCTIONS
Principles of operation
A preformed coil (6, 7), the rope coil (8), is inserted into the coil location
sockets (10) and then secured into place with the locking screws (11). The
coil then converts the current to a high frequency alternating magnetic
field. This magnetic field crosses the metallic, conductive work surface
(e. g., the nut/bolt) and vibrates the electrons in the metal through the
principle of electromagnetic induction. The kinetic energy of the moving
electrons is dissipated as heat, which rapidly heats metal within the
tool’s working range.
The induction heater heats ferrous metals and their alloys readily, but has
no eect on non ferrous materials, glass, plastics, wood, cloth and other
non conducting materials. The power trigger (9) is used to turn the power
unit on and o. Push it in to turn on power to the unit. The unit will re-
main on as long as pressure is applied to the switch. Remove pressure from
the switch to turn the power o. Unplug the induction heater when not in
use.
Preparation for use
Carefully read and understand all safety warnings and instructions in this
manual before operating the induction heater. Pay particular attention to
the safety rules in section SAFETY AND PRECAUTION instructions.
The induction heater is designed to operate from a normal 230V AC, 50 Hz
mains outlet, and will operate without suering damage on voltages of up
to 250V AC.
Generator use
Some portable generators, particularly low-cost units producing 4kW or
less, are unregulated and can produce in excess of 250 V AC which will
damage the unit and void the warranty. If you are in any doubt concerning
the generator that will be supplying power to the induction heater, have a
professional electrician measure the generator voltage with a digital volt-
meter. Measure the voltage with the generator engine warm and under
no load. With some generators the voltage may be reduced by decreasing
the engine speed.
Inverter use
DC to AC Inverter operation; Use only 2kw or larger sine wave inverter.
The use of square or quasi-sine wave inverter will void the warranty.

SAFETY SELF-PROTECTION
The induction heater has a unique safety self-protection feature: under
a number of conditions it will enter self-protection mode to protect the
internal circuitry of the induction heater; in this mode the current is cut,
the internal fan slows right down and the white LED at the front of the
instrument flashes.
Release the power trigger immediately the inductor enters the self-pro-
tection mode. Once the cause or fault is established and then rectified, the
inductor will function normally again.
Common reasons for the inductor to enter self-protection mode:
• Attachment or coil contacts loose: Securely locate coil ends in their
sockets and tighten the locking screws.
• Braid coil covering is torn, damaged or missing: Fit new, undamaged
coil.
• Fitting a coil that is too small, heat damages braid covering (see
diagram below): The coil must not touch the fastener or object being
heated, there must be an adequate air gap — 5mm minimum. No (or
too small) air gap will damage the braid covering as the object heats
up.
Coil too small – no air gap Larger coil – adequate air gap

USING THE PREFORMED COILS
The preformed coil is used to heat nuts, fasteners, caulking removal, door
hinges, exhaust manifold bolts, oxygen sensors, etc. The working life of the
preformed coil can be maximised by only heating objects enough to break
the rust bond. Leaving an air gap between the coil and the work piece is
recommended as the insulation of the coil will eventually burn through if
held directly to hot material.
1 Carefully follow the “Preparation for use” instructions.
2 Choose the appropriately sized coil to give the closest fit to the work
piece (nut/bolt etc.) ensuring an air gap of 5 mm.
3 Insert both ends of the coil into the coil location socket and tighten the
locking screws securely.
4 Place coil centrally over the work piece.
5 Activate the power trigger to run the induction heater until enough
heat has been applied to the work piece to break the rust/corrosion
bond.
Tip:
There is usually no reason to heat a nut to a red-hot condition in order
to free it from the corrosion holding it to the bolt.
6 Release the power switch to turn o the power.
USING THE ROPE COIL
The rope coil can be used to free a bearing race from an axle housing/hub,
remove rusted oxygen sensors, remove ball joints & track-rod ends, heat
exhaust pipe joints etc.
1 Carefully follow the “Preparation for use” instructions.
2 Insert one end of the rope coil into one of the coil location sockets and
tighten the locking screw securly.
3 Wrap the coil at least 3 times around the work piece to be expanded.
4 Insert the other end into the remaining open coil location socket and
tighten the locking screw.
5 Activate the power switch to run the induction heater until enough
heat has been applied to the work piece to break the rust/ corrosion
bond.
6 Release the power switch to turn o the power.

MAINTENANCE
Disassembly and storage
1 Turn unit o and allow it and all attachments to cool for at least 30
minutes before disassembly, cleaning or storage. Handling the unit or
parts before they have cooled may result in injury; storage of unit while
still hot may result in damage to equipment or pose a fire hazard.
2 When you are finished working, turn the power o by releasing the
power trigger and make sure that the internal fan stops.
3 Disconnect the plug (4) from the mains outlet or extension cord.
4 Once cooled suciently place unit and coils into foam cut outs in stor-
age case.
NOTE: Never disassemble the induction heater. If the sticker covering the
screw that holds the chassis together is removed, the warranty is not valid.
Cleaning instructions
• Make sure the unit is turned o and unplugged. Use a dry, clean, non-
abrasive cloth or paper towel to remove grease, oil, and other dirt from
the induction heater and electrical lead before returning them to the
storage case.
• For grease, oil and dirt that is more dicult to remove use a non vola-
tile cleaning product. Allow all components to dry completely before
using the induction heater.
• Do NOT immerse any components of the unit in water or a cleaning
solution.
• Do NOT spray the unit with water from a hose, or wash any parts under
a stream of water from a tapor shower.
• Do NOT clean any components with volatile organic compounds such
as petrol, benzene, kerosene, methyl ethyl ketone (MEK), fuel oil, brake
part cleaner, paint remover and thinners, varnish removers, plastic ad-
hesive solvents, etc. These substances are fire hazards and will harden
or dissolve the polymer materials used in the induction heater compo-
nents.
• Do NOT use heat guns, microwave or gas ovens, etc. to dry the compo-
nents of the induction heater

TROUBLESHOOTING
The induction heater is designed to stop running if the internal
components become overheated, however, the attachments DO NOT
have an overheat shuto. We recommend a 3 MINUTE duty cycle
with the induction heater. (3 minutes on – 3 minutes o).
If the unit stops suddenly: check to ensure unit is still plugged into a
functioning AC power outlet. Also be sure if using an extension cord
that there are no cuts in the cord. Allow the unit to cool o for at least
30 minutes and then retry.
If there is a lack of power output, this may be from using an improper
extension lead or a damaged attachment. Do not use more than one
extension cord at once.
