Warnings and safety precautions
This product is designed for fusing glass optical fibers for
communication purposes and should not be used for fusing
other substances. Incorrect handling may result in electric
shock, fire and personal injury. For the safety of the user,
please read and observe the following carefully.
Warning
Do not use power adapters, batteries, power cords, etc.
other than those specified for this product. Do not use
voltages other than those specified for this product as this
may cause a fire or electric shock.
Do not allow liquids such as water or metallic substances to
enter the interior of the machine, as this may cause fire,
electric shock or machine failure. In the event of water or
metallic substances entering the machine, stop using it,
unplug it from the mains and contact our maintenance
department.
Do not use the fusion splicer in a flammable or explosive
environment, as this may lead to fire or explosion.
Do not touch the electrodes when the fusion splicer is in
operation to avoid being injured by the high voltage
generated by the electrode discharge. Also when replacing
the electrodes the power must be switched off and the power
cord unplugged.
If you find that the machine is smoking, smells or makes
unusual noises, please stop using it immediately and unplug
it from the power supply and contact our maintenance
service. If you continue to use the machine, it may cause fire,
electric shock, machine failure and other accidents.
It is forbidden to dismantle or modify the fusing machine,
battery or power adapter to avoid heat, rupture or fire.
Please use the battery in strict accordance with the

5
operating instructions, as incorrect use of the battery may
result in heat, rupture, explosion, fire or personal injury
Caution
Do not use and store the fusion splicer in an environment
with high temperatures and humidity as this may cause
damage to the equipment.
Do not touch the heat shrink tube during or just after
heating, as the heat shrink tube is very hot and may cause
burns.
Do not touch the fusion splicer, AC power cord and AC plug
when your hands are wet as this may cause electric shock.
Do not use any chemicals other than alcohol to clean
microscope lenses, V-grooves, displays etc. as this may
result in blurred images, smudges etc. and may even cause
corrosion and damage to the equipment.
When used in dusty environments, appropriate dust control
measures must be taken to avoid large amounts of dust
entering the inside of the machine and causing it to
malfunction.
Do not subject the fusion splicer to strong vibrations and
shocks, as this may cause damage to the machine. Use a
special carrying case for transporting or storing the fusion
splicer.
Use the power adapter supplied as standard, if you use
your own adapter, the fusion splicer may not work properly.
Please check the battery level before using the fusion
splicer. If the battery level is low or there is an under voltage
alarm, please recharge the battery pack in time. (When the
battery is fully charged but still has a very short operating
time, please replace the battery with the specified type in
time).

Chapter 2 Basic operation
This chapter describes the basic operation of the fusion
splicer. Read this chapter in detail to use the equipment
correctly and to avoid problems such as damage to the
equipment and no normal results.
2.1 Power supply connection
The product supports the following two types of power
supply: internal lithium battery pack (no external power
adapter plugged in); external power adapter (external
power adapter plugged in). Plugging the DC output
cable of the adaptor into the external power connector
of the fusion splicer will charge the battery pack.
When the battery is too low, the fusion splicer will
display an alarm message on the display and the user
should promptly charge the battery pack or power it
with the power adapter.
When the battery is too low, the fusion splicer will show
an alarm message on the display and the user should
recharge the battery pack or use the power adapter to
supply power in time.

2.2 Power on and off
Short press the power button " " to turn on the
machine, the power button indicator turns red, the
buzzer emits "beep, beep" two sounds, after which the
display shows the working screen. Long press the
power button to switch off the machine, you can
observe that the display first turns off, the power
indicator flashes, and the indicator goes out after
releasing the hand, indicating that the fusion splicer has
been closed normally.

2.4.3 Removal and cleaning of fiber optic
coatings
After stripping the fiber, a dust-free paper moistened
with high purity alcohol is used to remove debris from
the coating layer, starting at the interface between the
coating and the bare fibre and rotating in a circular
direction towards the bare fibre.
2.4.4 Cleave the fiber
(1) Open the cleaver flap and place the stripped fiber into the
cleaver fiber holder slot, keeping the fiber perpendicular to
the cleaver surface.
(2) Slowly press down on the cleaver fiber holder flap and the
cleaver flap.
(3) Gently push the slider forward to cut the fiber.
(4) Open the cleaver flap and fiber holder flap and remove
the cut fiber.
(5) Remove the fibre scrap and place in the fibre scrap box.
Note: When the cutting end is not good or the fiber cannot be
cut, please adjust the cutter face; in addition, it is better to
use the cleaver that comes with the fusion splicer.
