2) Temperature control button: ( Note: The temperature control button
and the “ON/OFF” button are the same button. After powers on, the
button acts as temperature control button. )
Lightly press the button to change the preset temperature for heating
the gutta-percha. The temperature will change in the sequence of
150℃→180℃→200℃→230℃ as shown in Figure 1, and back to
150°when you press the button in 230℃.

3) Battery level:
The actual power of the battery is displayed in real time on the screen.
When the battery is fully charged, the power of the OLED display is
displayed as ve grids. When the battery level is one grid, it indicates that
the battery is low and needs to be charged in time. When the battery level
is displayed as a space, it indicates that the battery is very low and needs
to be charged immediately.
Note: During normal use, try not to let the battery level reduced to
space status (completely no power) before charge, which will shorten the
service life of battery.
Warning:
If the device has not been used for more than one month, the battery
needs to be recharged. If the device is not in use for a long time, please be
sure to charge it at least once a month to protect the battery. The service
life of battery of Melting and Filling Gun will be shortened when it is in
a low battery state for a long time or when it leaves the charging base for
a long time.
4) Temperature:
When the temperature is preset, the display screen shows the preset
temperature value. About 1s after the temperature preset, the OLED

4
screen will display the real-time temperature inside heating chamber.
When the Melting and Filling Gun is in the heating state, the
temperature indicator will simultaneously display the current temperature.
5) Charging base:
Firstly, connect the power adapter plug to the power adapter as shown
in Figure 2. Then connect the power adapter to the charging base as
shown in Figure 3 and connect the power adapter to a standard socket.
Place the Melting and Filling Gun correctly on the charging base as
shown in Figure 4, so that the charging connector under the Melting
and Filling Gun can be reliably connected to the output connector of the
charging base. When the Melting and Filling Gun is properly connected
to the charging base, the LED charging indicator on the base will be on
constantly. If the LED is ashing or not lit, please check all the cables
carefully.
There are charging status indicators on the charging base. When the
Melting and Filling Gun is not placed on the charging base, the indicator
will ashes in yellow and green alternately. When the Melting and Filling
Gun is placed on the charging base, if the charging is being charged,
the yellow indicator will be on constantly. When the battery is full, the
yellow indicator will be o and the green indicator will be on constantly.
Notes: After receiving the device, please charge it immediately.
Before use, please be sure that battery is fully charged. When the device
is fully charged, the battery level of the Melting and Filling Gun LED
display screen is the highest. After the battery runs out, the time of
battery charging takes at least 2 hours and 30 minutes.

6) Gutta-percha loading slot:
Note: Only gutta-percha can be loaded into it for a time.
7) Heat insulation hood:
The design of heat insulation hood is to protect the oral soft tissue and
lip from scalding.
Note: Before being used to dierent patients or before each use, please
clean, disinfect and sterilize the heat insulation hood.
8) Gutta-percha injection needle
Before use, the gutta-percha injection needle and the Fi-G must be
connected and tightened with the wrench provided by our company to
prevent the injection needle from falling o or the gutta-percha leakage
during use. But do not to screw too tight. Here we provide a variety of
injection needles with different sizes (Please refer to Table 2), and the
injection needles can be pre-bent depending on the application. ( Note:
Store unused gutta-percha injection needles in a sealed environment, as
the gutta-percha injection needle are made of silver and may discolor due
to oxidation caused by long-term exposure to air ). Please use the wrench
provided by the company to connect, disassemble and pre-bend the gutta-
percha injection needle.
Note: When replace the gutta-percha injection needle, please first
power o and wait for 5 minutes. Only after the Melting and Filling Gun
and gutta-percha injection needle cool down, the replacement can start.
When the gutta-percha injection needle is still hot, to avoid scalding,
please do not pre-bent or replace the gutta-percha injection needle.
Warning:
Before being used to different patients or before each use, please

recommended that users follow manufacturer's written instructions to
properly disinfect the device; the Melting and Filling Gun cannot be
autoclaved. Do not autoclave the Melting and Filling Gun and charging
base or place them in chemical disinfectants.
9) Wrench:
The wrench is used to tighten the gutta-percha injection needle
and its connection to Melting and Filling Gun. After tighten the gutta-
percha injection needle, the needle can be bent to any suitable angle with
wrench. Do not use other instruments to pre-bend the needle other than
the wrench provided by manufacturers.
10) Cleaning brush:
When cleaning the heating chamber with a cleaning brush, rst set the
preset temperature of the Melting and Filling Gun to 200 °C, then insert
the cleaning brush into the back of the Melting and Filling Gun, and then
push it hard to ensure that the cleaning brush is removed from the front of
the heating chamber. Do not remove the cleaning brush from the back of
the Melting and Filling Gun. When cleaning, you can repeat the cleaning
for several times to ensure that the heating chamber is well cleaned.
