Safety Matters for Attention
1. Signs & Definitions of Safety Marks
This Operation Manual and the Safety Marks printed on the products are to enable you to use this product correctly
so as to be away from personal injury. The signs and definitions of Marks are shown in below:
Danger
The incorrect operation due to negligence will cause the serious personal injury or even death.
Caution
The incorrect operation due to negligence will cause the personal injury and the damage of
mechanism.
This kind of mark is “Matters for Attention”, and the figure inside the triangle is the content for
attention. (Exp. The left figure is “Watch Your Hand!”)
This kind of mark is “Forbidden”.
This kind of mark means “Must”. The figure in the circle is the contents that have to be done. (Exp.
The left figure is “Ground!”)
2. Safety Matters for Attention
Danger
For opening the control box, please turn off the power and take away the plug from socket firstly,
and then wait for at least 5 minutes before opening the control box. Touching the part with high
voltage will cause the person injury.
Caution
Usage Environment
Try not to use this sewing machine near the sources of strong disturbance like high-frequency
welding machine.
The source of strong disturbance will affect the normal operation of the sewing machine.
The voltage fluctuation shall be within 10% of the rated voltage.
The large fluctuation of voltage will affect the normal operations of sewing machine, Therefore a
voltage regulator is needed in that situation.
Working temperature: 0℃~45℃.
The operation of the sewing machine will be affacted by environment with temperature beyond the
above range.
Relative Humidity: 35%~85%(No dew inside the machine), or the operation of sewing machine will
be affected.
The supply of compressed gas shall be over the consumption required by the sewing machine. The
insufficient supply of compressed gas will lead to the abnormal action of sewing machine.
In case of thunder, lightning or storm, please turn off the power and pull plug out the socket.
Because these will have influence on the operation of sewing machine.
Installation
Please ask the trained technicians to install the sewing machine.
Don’t connect machine to power supply until the installation is finished.
Otherwise the action of sewing machine may cause personal injury once the start switch is pressed

at that situation by mistake.
When you tilt or erect the head of sewing machine, please use both of your hand in that operation.
And never press the sewing machine with strength.
If the sewing machine loses its balance, it will fall into floor thus causes the personal injury or
mechanical damage.
Grounding is a must.
If the grounding cable is not fixed, it may cause the electric-shock and mis-operation of machine
The entire cables shall be fixed with a distance at 25mm away from the moving component at least.
By the way, don’t excessively bend or tightly fixed the cable with nails or clamps, or it may cause
the fire or electric shock.
Please add security cover on the machine head.
Sewing
This sewing machine can only be used by the trained staff.
This sewing machine has no other usages but the sewing.
When operating the sewing machine, please remember to put on the glasses. Otherwise, the broken
needle will cause the personal injury in case the needle is broken.
At following circumstances, please cut off the power at once so as to avoid the personal injury
caused by the mis-operation of start switch:
1.Threading on needles; 2. Replacement of needles; 3. The sewing machine is left unused or beyond
supervision
At working, don’t touch or lean anything on the moving components, because both of the above
behaviors will cause the personal injury or the damage of the sewing machine.
During working, if the mis-operation happens or the abnormal noise or smell is found at the sewing
machine, user shall cut off the power at once, and then contact the trained technicians or the
supplier of that machine for solution.
For any trouble, please contact the trained technicians or the supplier of that machine.
Maintenance & Inspection
Only can the trained technicians perform the repair, maintenance and inspection of this sewing
machine.
For the repair, maintenance and inspection of the electrical component, please contact the
professionals at the manufacturer of control system in time.
At following circumstances, please cut off the power and pull off the plug at once so as to avoid the
personal injury caused by the mis-operation of start switch:.
1.Repair, adjustment and inspection ;
2.Replacement of the component like curve needle, knife and so on
Before the inspection, adjustment or repair of any gas-driven devices, user shall cut off the gas
supply till the pressure indicator falls to 0.
When adjusting the devices needing the power supply and gas supply, users can’ t be too careful to
follow the entire Safety Matters for Attention.
If the sewing machine damages due to the unauthorized modification, our company will not be
responsible for it.
