1.1 Ambient temperature and humidity The temperature and humidity requirements of second-hand computerized embroidery machines are 5℃~35℃, relative humidity 45%~85% (no condensation). If the temperature is too high, it will be difficult for the computer to dissipate heat, and the electrical components may malfunction due to overheating, resulting in a decrease in the reliability of computer control; too dry air will generate static electricity, damage the integrated circuit, and be detrimental to people and machines; too humid air, not only This will lead to the occurrence of oxidative corrosion, poor contact and short circuit of the components inside the computer control system, and the wet embroidery thread will lead to a great increase in the thread breakage rate, which will affect the production efficiency.

1.2 Ventilation Second-hand computerized embroidery machines should be placed in a well-ventilated place, otherwise the machine will malfunction and affect normal production. Do not stack debris around the control box to facilitate heat dissipation.

1.3 Dustproof The embroidery machine has some guide rails and bearings that are exposed. Dust in the air will enter the surface of the guide rails and cause increased wear. In addition, if dust enters the computer box, it will also affect the work of the computer. Therefore, it is necessary to keep the environment clean and control the dust entering the workshop. There must be certain dust-proof measures, such as regularly using a vacuum cleaner, wearing slippers when working, and covering with a breathable cloth cover when shutting down, and cleaning the dust regularly (cleaning inside the control box should be done 2 to 3 minutes after the power is turned off. cleaning with a soft-bristle brush or hair dryer).

1.4 Selection of power supply In order to ensure the safe use of computerized embroidery machine, when selecting a power supply, do not use the same power supply with other heavy loads (such as high-power electrical equipment, large electric welding machines, etc.). In areas with large power grid fluctuations (more than ±10% of the voltage rating, single-phase 220VAC, three-phase 400VAC), a power regulator must be equipped, and the power supply must be greater than the power consumption required by the embroidery machine, otherwise it will affect the normal operation of the embroidery machine work.

1.5 Pay attention to electrical safety
(1) The connection wire between the power supply and the embroidery machine should preferably be embedded. Restricted by conditions, pipes (such as metal pipes and flame-retardant plastic pipes, etc.) can also be used to connect to a suitable position next to the embroidery machine.

(2) Switches and plugs must be products with the CCC certification mark to ensure reliable connection between the power supply and the embroidery machine.

(3) The embroidery machine must be connected to the ground wire and ensure a reliable connection with the ground. The grounding resistance is less than or equal to 10Ω, and the grounding wire should be made of copper core wire with a cross-sectional area of ​​not less than 2.5 mm2, depending on the length of the grounding wire.

1.6 Grounding A series of problems such as radio frequency interference, system crash, and pattern movement may be solved by changing the placement direction of the embroidery machine. The best thing to do is to be sure to use a good shield grounding.

1.7 Turning on and off Do not turn on and off frequently, and the interval between the second startup must be more than 3 minutes. Because the current generated at the moment of switching on and off is 3 to 5 times larger than that during normal operation, frequent switching will cause the local heating to be too fast or the computer control system to be overloaded, which will affect the service life of the embroidery machine and cause the system to fail to work normally.

1.8 Fuse Replace the fuse in strict accordance with the specifications marked on the product. If the inside of the fuse tube is found to be black, you should contact the service personnel in time to ensure the safety of personnel and property.

1.9 Avoid sunlight exposure The machine should avoid sunlight exposure. It is easy to damage the LCD screen if it is illuminated on the operating head. If it is illuminated on the beam, it will easily cause deformation of the beam, which will cause wire breakage and needle breakage, so that the machine cannot work normally, so sunshade must be adopted. measure.

1.10 Lightning protection Lightning can easily cause damage to the computer control system, so lightning protection measures should be taken in thunderstorm weather until the power is cut off.

1.11 Use If the machine is used for the first time or needs to be reconnected to the power supply, use a multimeter to measure the voltage of the external incoming power supply, whether it meets the normal operation requirements. After connecting the power supply of the embroidery machine, measure the power supply voltage of the terminals, which should be consistent with the nominal value of this product. Computer embroidery machine operators must pass safety and operation training before they can get on the machine to ensure the safe operation and normal use of the equipment; when the machine is turned on, do not touch any mechanical transmission parts or open the cover of the control box, otherwise it may damage the equipment. and damage to the operator. The disconnection detection switch is frequently used in work, and the operator is required not to use excessive force when flipping the switch, otherwise it will easily damage the switch or shorten the service life of the switch. The disk drive is a precision device. When inserting the disk, you must identify the direction; when the disk is being read (the prompt light on the drive is on), never take out the disk, which will seriously damage the disk and the drive. Use guaranteed quality disks, use of poor quality disks will seriously damage the disk drive. The magnetic disk is a product of magnetic material, and should be kept away from objects with strong magnetic fields such as magnets and TV sets; otherwise, the disk will be damaged and data will be lost. At the same time, keep it clean and avoid pressure and moisture. In case of a sudden power failure during work, the power switch of the machine should be cut off, and at the same time, avoid any objects touching the frame, and turn the color-changing box to avoid damage to the machine. The operation buttons are the most frequently used parts and are easily damaged. Press them carefully during use. It is forbidden to press the buttons directly with fingernails or hard objects.

1.12 For machines that have been out of use for a long time
(1) Moisture-proof treatment must be carried out when restarting the machine. The method is to open the cover of the electrical box and dry the circuit boards with a hair dryer. Power on.

(2) The wire-passing part should be checked and cleaned to ensure the flexible operation of the wire-passing wheel.

(3) Clean and refuel other mechanical transmission parts, especially the circular drive rail parts must be rust-proof.

(4) Qualified users should start the machine every 2 to 3 days (2 to 3 hours to avoid moisture), and at the same time check whether the signal connectors, the power terminal block are firmly connected, whether the wires are damaged, and whether the insulation is in good condition. Especially for users in southern my country, it is very necessary to adopt the above methods in the rainy season.

1.13 Use special spare parts Use special spare parts, otherwise it is easy to expand the fault range, cause unnecessary damage, and affect the performance and service life of the whole machine.
