3. The water protection system should be inspected and cleaned regularly. It is recommended to use pure water and other direct drinking water, otherwise scale will appear after a period of use, and the parts will be damaged, resulting in the inability to open the protective float switch, which directly affects the use of the laser engraving machine ；

4. The suction device should be inspected and cleaned regularly. If it is not cleaned for a long time, the dust will not be discharged, which will affect the cleaning of the equipment, interfere with the work of the lens and the laser tube, and the dust will easily cause poor contact of the mechanical parts;

5. Focusing lens and reflector need to be inspected every day, and under the condition of continuous working for a long time, the frame of the lens will easily cause discoloration and rust on the surface of the lens, cracking of the coating, etc. At this time, it is necessary to replace the accessories; and the peeling and cracking belong to The scope to be replaced, especially some customers will use atmospheric pumps and air compressors, so it is easy to produce water on the focusing lens. Failure to deal with it in time will affect the optical path and affect the normal use of the laser engraving machine;

6. The working environment of the laser engraving machine also has certain requirements. It is recommended to use it at no higher than 30 degrees and no lower than 20 degrees, and the indoor environment should not have too much dust, otherwise it will easily affect the parts and the failure rate It is also gradually increasing, and it is not easy to use in a humid or excessively dry environment, which also has a great impact on the maintenance of the machine;

7. The electrical power should be stable. Repeated and incorrect power-off of electrical appliances will affect the service life of the machine, and frequent high and low voltage will also easily cause the service life of the laser engraving machine;

8. The working current of the laser tube should be reasonable. Working under 90-100 light intensity for a long time will not only consume a lot of energy, but also cause excessive use of the optical system, which will affect the service life of the laser tube. It is recommended to clean the laser tube frequently to prevent overuse. Premature aging and cracking. It is recommended to adjust the optical path of the laser engraving machine at 50-60, and then adjust the speed according to the engraving material in order to achieve a good working state;

9. The stability of the machine must be strong, and the bottom plate and receipt must be vouchers, otherwise the operator will adjust the light path to facilitate the penetration when operating, and this zoom will easily cause the aging of the laser tube;

10. The heat dissipation system of the laser power supply of the laser engraving machine should be flexible and unobstructed, so as to ensure that the temperature rise caused by the adjustment of the speed will not cause timely heat dissipation and induce the use of the laser engraving machine.
