Before using this machine tool formally, please master the relevant operation methods of the machine tool and understand the various parts of the machine tool. Operating conditions and correct operation are effective measures to ensure the normal operation of the machine tool and personal safety. use When the machine tool is used, please strictly follow the preparations and inspections before use to conduct relevant inspections. 2. Preparation and inspection before use a) Check that the power connection is normal. b) Check whether the lubricating oil level of the machine tool is within the normal range, otherwise add lubricating oil to the normal range. c) Check the coaxiality of the laser and the gas nozzle to ensure that the laser beam is emitted from the center of the gas nozzle. d) Check whether the air nozzle meets the cutting process requirements, otherwise, replace the appropriate cutting air nozzle. e) Check whether the auxiliary gas for cutting is connected normally, otherwise connect the corresponding auxiliary gas for cutting, and ensure that the gas pressure has been adjusted to the normal range. 3. Safety and safety protection, safety signs and instructions before and during use Indicates “Caution”, failure to follow proper operation may result in personal injury or cause damage to the equipment. Indicates that there is a laser beam passing through, do not pass through the beam, otherwise it will cause damage to the human body Burns are even life-threatening. Indicates that there is a danger of high voltage power supply, do not approach high voltage, otherwise it will cause damage to the human body Electric shock can even be life-threatening. Precautions: a) No one, at any time, should put their eyes in the direction of the laser (including the red indicator light) Towards. b) When opening the mechanical shutter, prohibit people and non-working objects from being within the laser irradiation range. c) The operator should wear protective glasses, and it is strictly forbidden for the operator to leave during the operation of the machine. d) If an abnormality occurs during the use of the machine tool, the emergency stop switch should be pressed immediately. e) During use, the cooling water temperature and working gas pressure should be checkedfrequently. f) Operate the equipment with the operating license, observe the safety operation rules, and it is strictly forbidden for non-workers of this machine tool to operate. g) The laser equipped with this machine tool is a Class 4 laser product. The fiber laser is invisible light, and the diffuse reflection of the emitted beam may cause damage to the human body (especially the eyes). Fire should be prevented. h) Exhaust gas generated during laser cutting is harmful to human operators. Please ensure that the dust collector of the machine tool normal work. i) Always keep the equipment clean and tidy, refuel according to regulations, and ensure reasonable lubrication; Good tools and accessories should not be lost; if a fault is found, stop the machine immediately to check, and should not deal with it by yourself. Notify maintenance in time. j) To prevent electric shock injury, non-professional maintenance personnel are strictly prohibited from checking and overhauling the electrical control part of this machine tool.
