After closing the power switch and unplugging the power plug from the socket, wait for at least 5 minutes
before opening the control box cover. Touching areas with high voltage can cause casualties.
No liquid is allowed to enter the sewing machine, otherwise it will cause fire, electric shock and operation
failure.
Use Environment
Please don't use in the environment with strong electrical
interference sources such as power line interference and
elec trostatic interference.
Strong electrical interference sources may affect the correct
operation of sewing machines.
The fluctuation of power supply voltage should be used in
the environment of rated voltage less than ±10%.
The large fluctuation of voltage will affect the correct
operation of sewing machine.
The power supply capacity should be greater than the
power consumption of the sewing machine. Insufficient
power supply capacity will affect the correct operation of
sewing machine.
Warning
Be Careful
If any liquid enters the sewing machine (head or control box), turn o ffthe power supply immediately, pull
the plug out of the socket, and contact the vendor or senior technicians.
The ambient temperature should be used in the range of
5-35 degrees Celsius.
Low or high temperature will affect the correct operation of
sewing machine.
Relative humidity should be in the range of 45% - 85%, and
the equipment will not form condensation environment. Dry
or wet environment and dew will affect the correct
operation of sewing machine.
In case of thunderstorm, turn off the power switch and pull
the power plug off the socket. Lightning may affect the
correct operation of sewing machine.
Do not connect devices other than USB memory to USB
connection ports. Otherwise, it may lead to failure.
Ask trained technicians to install sewing machines.
Please commission the purchase shop or electrical
professionals for electrical wiring.
The sewing machine weighs about 38Kg. Installation must
be completed by more than two people.
Please do not connect the power supply before the
installation is completed. If you step on the pedal by
mistake, the sewing machine will cause injury.
Please unplug the plug after cutting of f the power supply.
Otherwise, it will easily become the cause of the failure of
the control box.
It must be grounded.
Insufficient ground connection is the cause of electric shock
or misoperation.
When fixing the cable, do not bend the cable excessively
or fix it too tightly with clamps, which may cause fire or
electric shock.
If a worktable with casters is used, the casters should be
fixed so that they cannot move.
When the head of the sewing machine falls down, please
make sure that the worktable is fixed and not moved at will.
Accidents such as foot clamping have occurred in the
movement of worktable, which is the cause of personal
accidents.
When the sewing machine head falls down or stands up, ple
ase operate with both hands.
One-handed operation can easily cause injury if the weight of
the sewing machine slips.
When lubricating oil and butter are used, it is necessary to
wear protective glasses and gloves to prevent lubricating oil
from falling into serious or sticking to the skin, which is the
cause of inflammation.
In addition, lubricants or butter should not be drunk,
otherwise vomiting and diarrhea will occur.
Keep oil out of reach of children

Precautions Prior to Startup
Precautions for Use
1
1. The machine head is coated with a thick layer of rust-prevention grease before encasement,
and the encased machine head may possibly be subjected to grease hardening and dust buildup
on the machine surface in process of long storage and
long-haul traffic; therefore, take care to remove the grease and dust from the surface using soft
cloth and gasoline.
2. Though the machine was inspected and tested with care before factory leaving, it might be
affected by violent vibration resulting in looseness or distortion of the machine parts; therefore the
operator shall thoroughly check the machine, turn the upper wheel by hand and check it for
difficulty in free rotation, slight impact, and other uneven resisting force or abnormal noises, and
make appropriate adjustment if any to restore the machine state before formal trial run.
3. Never start up the machine if the oil liquid level in the oil box falls outside the normal range.
4.The upper wheel shall rotate counterclockwise (when it is viewed from the lateral surface of the
upper wheel) when the machine is operating.
5. Check whether the voltage and phases indicated on the electric-control data plate are correct.
6.The date of manufacture is indicated on the certificate of conformity.
2
1.Never touch the needle by hand when the machine is powered on or while it is operating.
2.Never put your finger into the protection cover of take-up lever during operation of the
machine.
3.The operator must not put his finger into the needle guard bracket when he feeds the
sewing materials by hand.
4.Operator must trim off the electricity supply before he turns over the machine head or
removes the hand cover.
5.The operator must trim off the electricity supply before he gets away from the machine.
6.Prohibit the head, hands and anything to approach the upper wheel and bobbin winder
while the machine is operating.
7.Never remove or mount the protection cover or other protection devices before the
machine is stopped.
8. Never wipe up the surface of machine head using paint thinner such as acetone.

1.Ad
justing the bobbin thread winding
1)To adjust the winding capacity of bobbinthread, unscrew fixing screw ⑤ ,set winding lever ③
in direction A or direction B, and fix screw ⑤ again. Direction A is intended for reduction, and
direction B is intended for increase(CCaution:The amount of thread wound onto the bobbin
should be a maximum of 80% of the bobbin capacity).
2.If thread cannot be wound onto the bob
bin flatly, unscrew nut ⑥ , turn the winding tesion disco, and adjust the height of height of thread
gripper plate ⑦.
a. The standard position is reached once the center heights of rotating hook ① and thread
gripper plate ⑦ are identical.
b. If the winding amount on the lower part is bigger, move the winding tension discoin direction
D indicated in the right hand figure.
3.If the winding amount on upper part is bigger, move the winding tension disco in direction E
indicated in the right-hand figure.
When the winding tension disco reaches its suitable position, screw down fixing screw ⑥ .
Adjust the winding tension of bobbin thread by turning thread tension nut ⑧. Thread the needle
thread when needle bar stays in its highest position, lead out the thread end from the thread
stand, and conduct threading as per the serial numbers indicated in the figure.
