The stone cutting machine is a compulsory certification product stipulated by the National Certification and Accreditation Administration. Therefore, when purchasing, you should first check whether the product has the 3C mark. The general method of checking is whether it is on the outer package of the tool or on the nameplate of the tool. If you still have doubts about the 3C mark (because the manufacturer of the electric tool has not passed the annual supervision and review, the CNCA suspends or revokes its certificate), you can go to the website of the CNCA to check whether the 3C certificate of the tool is Currently valid.
According to the needs of users, first distinguish between home use and professional use. Since most electric tools are designed for professionals, you should distinguish between professional and general household work shells before purchasing. Generally, the difference between professional and general household tools is in power. The power of professional tools is larger to facilitate the professionals to reduce the workload. The general household tools are relatively small due to the smaller engineering and relatively small workload, so the tools are more powerful. The input power does not need to be large.

Observe the outer packaging of the stone cutting machine. The outer packaging should have clear patterns and no damage. Open the box and observe the appearance of the stone cutting machine. The color should be uniform. There should be no obvious shadows and dents on the surface of the plastic parts, and there should be no scratches or bumps. , The assembly misalignment between the shell parts is less than or equal to 0.5mm, the aluminum casting coating is smooth and beautiful without defects, and the surface of the whole machine should be free of oil and stains. When you hold it with your hands, you feel better, and the handle of the switch should be flat. The length of the cable should generally not be less than 2 meters.

Check the nameplate and manual of the stone cutting machine. The parameters of the nameplate should be consistent with those on the 3C certificate. The manual should have the detailed address and contact information of the manufacturer and the manufacturer. There should be a traceable batch number on the nameplate or certificate. Hold the stone cutting machine by hand, turn on the power, and frequently operate the switch by hand to start the tool frequently, and observe whether the on and off function of the stone cutting machine is reliable. At the same time, observe whether there are any abnormalities in the TV and fluorescent lamps on site. In order to confirm whether the tool is equipped with an effective radio interference suppressor. The stone cutting machine is energized and operated for one minute. Hold it with your hand during operation. You should not notice any abnormal vibration in your hand. Observe the reversing spark. The reversing spark should not exceed 1.5 levels, generally from the air inlet of the tool. From the inside, there should be no obvious arc on the surface of the commutator. During operation, there should be no abnormal noise, etc.
