In order to ensure the safety of users, Sichuan tools should be used in general places. If you use |, you must use a leakage protector and a safety isolation transformer. Otherwise, the user must wear insulation gloves, wear insulation boots or stand on an insulation platform (pad)
2. In wet places or workplaces with good electrical conductivity such as metal frames, mountain or Sichuan tools should be selected. If the tool is used, it must be installed with a leakage protector with a rated leakage action current of no more than 15mA and an operation time of no more than 0.1s.
3, in narrow places such as boilers, metal containers, metal pipes, etc., should use Sichuan tools. If Sichuan tools are used, they must be installed with a leakage protector with a rated leakage current of no more than 15mA and an operating time of no more than 0.1s.
4, special environments, such as hot and humid places, outdoor rain and snow, and places with dangerous or corrosive gases, the use of power tools should meet the safety technical requirements of the corresponding protection level.
5. The power cord of the tool must be three-core (single-phase tool) or four (three-phase tool) multi-strand copper rubber sheathed soft cable or sheathed wire, of which the yellow and green two-color wire can only be used as a protective grounding or neutral line in any case
6, the safety isolation transformer of Sichuan tools, leakage protector of l tools, and the control box and power adapter of Sichuan and M tools should be placed outside, and a special person should be monitored outside
7. Before use, check whether the tool shell and handle are broken and damaged, whether the protective grounding or zero connection is correct, firm and reliable, and whether the wire and plug are intact; open
Whether the action is normal and flexible; Electrical and mechanical protection devices are in good condition; Whether the rotating part of the tool is flexible and barrier-free. 8, the use of power tools do not hold the wire or the rotating part of the tool, the use of the process to prevent the wire is tattooed, damp, heat or damage. 9. It is strictly prohibited to insert the conductor core directly into the socket or hang it on the switch
10, the soft cable or cord of the power tool shall not be arbitrarily long or disassembled. The plugs and sockets used should meet the corresponding national standards. The plug socket with a ground pin should conform to the specified contact sequence when plugging in to prevent misinsertion.
