People who has an artificial heart pacemaker, who has similar electric
medical device should avoid using or nearing this device.
1. Heating rusted bolt nut, by the purpose of fast and easy remove from
machines, cars etc. Using the thermal expansion theory, when the nuts
of the bolt is heat, it expands which makes it easy to be removed from
rusted bolt.
2. A flat coil will enable the device to remove stickers .
FUNCTIONS
SAFETY CAUTIONS
Page 3
For professional use only.
Avoid wearing a ring, other metal jewelries, key, watch or any metal
gadget, any cloth that has metal rivets nearing the induction coil,
electromagnetic induction may cause high temperature of such metal
parts and may lead to skin burn or burning of cloth.
If the heating element has deposition of toxic or become toxic matters
due to high temperature, operator must wear anti poison gas mask or
equal safety protection.
Electric shock can cause death.
Clear inflammable, explosive matters near the working area before use.
Protection gloves should be wear during use.

DEVICE DESCRIPTION
OPERATION STEPS
1.Release the 2 fixing bolts contraclockwise 0.5cm out.
2.Select appropriate size of coil for your work and insert the two ends into
the front holes.
3.Twist the bolts clockwise to fix the coil tightly.
4. Plug in and place the heating element in the center of the coil, then
press & hold the red button, the light in front will shine simultaneously.
5. At the same time, the heating elements' temperature raise, when work is
done, release the button, and put it in safe place.
Fix the coil to this place

1.This device is built in the over heat protection, it will shut itself off to prevent
damage from overheat, you can use it after the temperature back to normal .
2.Please try not to use it over 2 minutes one time, although the device is built in
the over heat protection, however, life spam of the device may be reduced.
3.During use, please place the coil in the center of bolt/heating object, try not to
reach or close to large metal part where you don’t need to heat), otherwise it
will increase working load and slow heating speed of bolt. Please refer to Pic 4.
4.When the white coil insulation is breach, please replace with new insulation
pipe, or replace the coil, if you have to use it, please not use it in the way of Pic
1, Pic 2.
(Breach of insulation pipe may lead to short circuit of induction coil, thus
may cause irretrievable damage to the heater)
5.Do not block the back end fan during working, otherwise cooling ability will
decrease, and cause overheat of the device very soon.
6.Please don't put this device in fridge, near the air conditioner vent, this may
cause condense water inside of the device and may damage the board.
7.Please don’t bend the power cord sharply, no matter in using or storage.
8.Please don’t open the device by yourself .

2. Metal surface temperature will be 50-60 °C lower.
3. Temperature over 550 °C may lead to annealing to the nut, directly
affect iron mechanical properties, so recommend heating temperature
is below 500°C

TROUBLE SHOOT
Items
Solutions
No response after pressing
“ON” button, no indication
light on, no fan working, no
increasing heat of heating
object.
1. Check if the plug is broken;
2. If plug is firmly plugged in;
3. If the switch on the socket is on;
4. Or the fuse in the plug (British
type) is damaged;
Indication light is on, cooling
fan is on, slow heating speed;
1. If using large coil for small
diameter bolt, difference is more
than 20-30mm.
2. If the front coil is breach or off,
and the turns of coil attached to
each other.
3. Please placetheheatingobjectin

metal will consume a part of
heating power.
Heating duration did not last
for 1minute before shutting
off.
1. Check if the insulation is breach
and the coil has contact with bolt
and lead to short circuit.
2. If the heating bolt is surrounded
by metal object, which will
increase the load of the device.
please clean the surrounding
metal or concentrate power to the
bolt.
3. After device recover to normal
function, heat still remain in the
device, please wait longer time to
