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
electrostatic 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 off the 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 off 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
move -ment of worktable, which is the cause of personal
accidents.
When the sewing machine head falls down or stands up,
please 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
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.
Precautions for Use

-3-
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.

-rt is bigger, move the winding tension disco
in direction D indicated in the right-hand figu
-re. If the winding amount on upper part is bi
-gger, move the winding tension disco in dire
-ction E indicated in the right-hand figure.
c.When the winding tension disco reach
-es its suitable position, screw down fixing s
-crew ⑥.

panel moving distance is 1.3times than origin
-al one. Move reversely the distance is 0.8 tim
-es as original one.
3)Assembly the nut ⑧ after adjusting panel
moving distance.

Oil mass Adjustment of Rotating Hook (Fig. 23, Fig. 24 , Fig. 25)
1.Adjustment method
1) Adjust the oil mass of rotating hook using
adjusting screw ①: Screw down (turn it to the
right) adjusting screw ① to raise the oil mass
,or unscrew (turn it to the right) the adjusting
screw to lower the oil mass.Amount repeate
-dly until the lubrication amount is correct.
2)Check the lubrication amount again after
the sewing machine has been used for appr
-oximately two hours.
Caution:
1.To prevent the unexpected startup of
sewing machine, trim off the power supply
before the operation is conducted.
2.Confirming the Oil Mass
1) Remove the thread from all points from
the thread take-up to the needle.
2) Use the lifting lever to lift the presser foot.

3) Run the machine at the normal sewing s
-peed for approximately 3 minute without se
-wing any material (following the same start
/stop pattern as when actually sewing)
4) Place the lubrication amount check she
-et ② underneath the rotary hook ③ and hol
-d it there.Then run the sewing machine at t
-he normal sewing speed for 10 seconds.(A
-ny type of paper can be used as the lubrica
-tion amount check sheet ②)
5) Check the amount of oil which has spat
-tered onto the sheet ②.
Caution:
1.Prior to the above-mentioned opera
-tion, remove the knockout plate and
check whether there is oil in the oil box.
2. Do not use fingers to touch the hoo
-k or other running components of fe
-eding mechanism when checking the
amount of oil for the hook to avoid the
accident.
3. Use the following procedure to che
-ck the amount of oil being supplied to
the rotary hook when replacing the ro
-tary hook or when changing the sewi
-ng speed.
3.Guide sample of oil mass adequacy
1) The guide sample shown in the right-ha
-nd figure(see Fig. 10) may be finely adjuste
-d (increased or reduced) as per different se
-wing processes; however, excessive increa
-se or reduction shall be avoided. Too little o
-il mass may lead to rotating hook heating, a
-nd over much oil mass may lead to contami
-nation of the sewing materials.
2)Test the oil mass 3 times using special
oil mass confirmation paper till the oil traces
indicated by the special paper show no chan
-ges.
