In order to purchase a satisfactory stone cutting machine, the following points should be noted.
1. 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 method of inspection is generally on the outer packaging of the tool or on the nameplate of the tool. Whether there is a 3C mark, if there is still doubt about this (because the manufacturer of the power tool has not passed the annual supervision review, the CNCA suspends or revokes its certificate), you can go to the website of the CNCA to check the 3C of the tool. Whether the certificate is currently valid.

Usually, the difference between professional and general household tools is in power, and the tools used in professional use are relatively large, so that the professional can reduce the workload. The tools used in general households are relatively small in engineering and the workload is relatively small, so the tools are The input power does not need to be large.
Fourth, observe the outer packaging of the stone cutting machine, the outer packaging should be clear in pattern, no damage, open the packaging box to observe the appearance of the stone cutting machine, the color should be uniform, the surface of the plastic parts has no obvious shadows and dents, there should be no scratches or Bumping marks, assembly misalignment between shell parts ≤0.5mm, aluminum castings coating smooth and beautiful without defects, the surface of the machine should be free of oil and stains.

The serial number of the product traceable should be on the nameplate or certificate. Hold the stone cutting machine by hand, turn on the power, and frequently operate the switch by hand to make the tool start frequently, and observe whether the on/off function of the stone cutting machine switch is reliable.

In order to confirm whether the tool is equipped with a valid radio interference suppressor. The stone cutting machine is energized for one minute, and the hand is held by hand.
