Strictly comply with the operating instruction and be trained before operating the machine. All staffs must wear safety helmets before enter the working area.
Inspect and ensure the three phases of power supply are normal before using the equipment. Make sure with good grounding protection and effective protection device before operating the machine. Lightning rod should be mounted in mountain area to avoid personal injury and equipment damage due to lightning stroke.
The working area of machine should be placed with or put up with warning signs “Dangerous area, No entry” to prevent from accidental injury due to non staff admittance to the worksite.
The operating floor should be put up on the lateral face of the saw rotation and far away from the machine. Be far away from the cutting quarry stone. Pay attention to mountain slid. Watch out for the cliffs behind and prevent slip and fall.
The rail should be laid and connected flat and firmly. The inclination of rail can not be too steep. After installation of the machine, adjust the fly wheel to the same face with the sawing face of stone. When sawing in horizontal direction, the two guide wheels should be placed in front of the rail to confirm the straightness of sawing face.
Adjust the tension of wire saw to easy pull by two people. Confirm the safety protection device and the warning signs are placed. The machine can start up when staffs stay out of the safety device. Keep the wire saw work in a constant speed. The machine should stop for inspection when sawing with severe jumping.(the jumping is reduced from unsuitable tension of the wire or the different running tracks between the driving wheel and guide wheels)
Cooling the wire saw in the cutting inlet and outlet along the sawing direction through at least two water pipes. Move and adjust the water pipes to control water flow from the lateral face of the sawing gap. The water flow should be appropriate and it is not good for sawing when the water yield is too large or too small. Discharge with slurry in the sawing outlet will be good.
Manually operate the machine when start sawing. The machine can then be changed to automatic control just after the sharp point of the saw is worn out. The moving speed of machine can’t be too fast to protect the wire saw. The operator should not leave the machine to ensure safety. The sawing of machine should be changed to manual control when stone sawing is nearly finished and to reduce the moving speed of the machine gradually.
Any people can't stand in the same direction of sawing or go through the wire saw when the machine is sawing in vertical direction. A safety shield should be put up around the saw to prevent personal injury when sawing horizontally in case of the break of wire saw.
The machine should stop for inspection of the wire saw connector after the machine works for continual ten hours. The wire saw must be replaced in time to prevent breaking while the wear of the wire saw connector is increased.
The cutting edges should be in the same direction when multi- wires are connected. Wire saws of severe wear can’t be used for sawing large plane. Wire saws with different wear can’t be used at the same time.
The machine should stop moving backward before stop. The wire saw should idle for a short time to enlarge the sawing slot so as to restarting of machine. And then move the machine forward so that the wire saw is loosened to prolong the life time of machine.
Disconnect the power supply while finish sawing every time and wash the slurry of the machine in time.
