3.3.2 Heating
Place the heating tip on the element to be heated, then press the
heating switch (1), the LED backlight (2) will light up, which means
that heating has begun. After the element is sufficiently heated, let
go of the heating switch (1), the LED backlight (2) will turn off and
the device will stop heating, but the built-in fan will continue to
work, cooling the device. Put the device in a safe, stable and
fireproof place. Before disconnecting the device (plug) from the
power supply, wait at least 5 minutes for the fan to cool down (to
switch off).
PLEASE NOTE: never touch the heating tip with any part of your
body or bring it close to the body during or immediately after
heating – there is a risk of severe burns!

Heating with a heating coil
Heating coils (10-12) are intended for heating bolts, nuts,
clips, removing seals, seized door hinges, bolts in exhaust
manifolds, cargo holds and van or truck crates, lambda
probes, etc.
In order to extend the life of the heating coil, the element
should be heated to the extent allowing to dismantle it;
avoid overheating the element as temperature may lead to
burnout of the heating coil insulation. Usually, there is no
need to heat the element until it is red-hot, just a few
seconds of heating or a few-second trials will be enough as
a start. During heating, the coil should not touch the heated
element - keep a distance of approx. 3-4 mm between
them.
Heating with a "U" shaped tip
The "U" heating tip (13) is universally applicable, moreover,
you can shape it, for example while repairing dents in
metal. To do this, form it like in the picture below:
