1 Safety Instructions and Precautions t is strongly recommended that any personnel who are involved with the operation or maintenance of this equipment should first read the contents of this manual. Only authorized personnel who have been instructed in and fully understand the necessary safety procedures must use this equipment.
Page 6 1.1.2 Some important instructions:  1325/1530 is using laser to cut. Laser light, because of its special properties, poses safety hazards not associated with light from other sources. The safe use of lasers requires that all laser users and everyone near a laser be aware of the dangers involved in laser operation.
Page 7 associated with light from other sources. The safe use of lasers requires that all laser users and everyone near a laser be aware of the dangers involved in laser operation. Only authorized personnel who have been instructed in and fully understand the necessary safety procedures must use this laser equipment.
Page 8 Safety precautions Exercise caution to protect against specular reflections since reflections at the laser wavelength are invisible. Eye safety is great concern when using a high-power laser. There are often many secondary beams present at various angles near the laser. These beams are specular reflections of the main beam from polished surfaces.
Page 9  Avoid operating the laser in a darkened environment. Do not use the laser in the presence of flammables, explosives, or  volatile solvents such as alcohol, gasoline, or ether. For additional information on laser safety, refer to the following publications: ...
Page 10  The cable that connected with power supply should be long enough and have damage-protecting external cover. The numerical control system of this machine has strict requirements for the input voltage. Manostat is strongly recommended, to ensure the voltage conform to the requirements for the voltage.
Page 11  The water cooler system should have been running for ten minutes before operating the cutting machine. And check the whole water cooler system, to ensure there are no air bubble in the pipe. Before operating the cutting machine, check each parameter setting, to ensure there are no air bubble in the pipe.

2.3 Machine structure Laser Cutting Machine (figure 2-1) contains of laser unit, the cutting machine, control system, water chiller. Figure 2-1 Laser cutting machine 2.3.1 The cutting machine The cutting machine consists of the base, worktable, gantry frame, cutting head and operating panel. The worktable fixed on the base, and the gantry frame 15 / 36...
Page 16 moves on the rails fixing on the base. The laser unit and the cutting head move on the rails fixing on the gantry frame. There are four casters under the base. The left is the cabinet containing all electric components. The right near the back is the vent, connecting it to exhaust by pipe, thus can vent exhaust gas that cutting made.
Page 17 beam delivery system includes reflecting mirror and lens. (figure 2-3) A,B,C ,D,E are reflecting mirrors and F is lens. Figure 2-3 The Laser Unit Laser head was fixed in the shield. When cutting workpiece, should prevent optics lens from being damaged by high reflectivity material.
Page 18 must filtrate by the clean air system, to ensure the accessorial cutting gas conform to the purity requirements. Refer to figure 2-4. When use the compressed air, you should provide oil mist seperator, filter and dryer, to ensure the particles is smaller than 5μm, the content of condensate is lower than 5mg/m , the content of oil is lower than 0.1 mg/m .

Page 20 3. Installation and Utility Requirements 3.1 Hoist and transportation It is necessary to fix the moving parts and the whole machine when packing. Pay attention to machine net weight and the position of center of gravity while the machine is being hoisted. The jacks should have enough carrying capacity. It is strongly recommend that moving the machine must be lightly, slowly and smoothly, and collision and leaning should be avoid.

The groundwork should be tamped. the cement is No. 400, its thickness is more than 50mm. It is recommended that the ground should be covered with water millstone or lacquer. Brush the wall surface with the white lacquer. The door and windows should have well hermetic characteristic. Plastic steel is recommended.
Page 22 3.4.1 Power supply requirement: The main power supply is single-phase 220V 60Hz, full current is 13A the voltage range is 220V±10%. And the area of lead cross section is more than 2.5mm The numerical control system of this machine has strict requirements for the input voltage.
Page 23  Any time, you can start chiller again more than three minutes later after the chiller’s power off, otherwise the chiller can be easily damaged.  Prevent wiring from being sprinkled, otherwise conducing creepage and damaging the chiller.  Do not touch inside, prevent high speed fan and high temperature from hurting body.
