1) Before energizing mobile power tools and hand-held power tools, the protective earth or protective zero should be connected.

2) Mobile power tools and hand-held power tools should be equipped with a separate power switch and protection. It is strictly forbidden to connect two or more electric equipment to one switch.

3) The power switch of the mobile electric tool should adopt a leakage protection device, the action current should not be more than 15mA, and the action time should be less than 0.1s. The switch should be installed in an easy-to-operate place, and the distance between the tool and the tool should not be more than 5m.

4) When portable power tools and hand-held power tools are connected by sockets, their plugs and sockets should be free from damage, cracks, and good insulation.

6) Mobile power tools and hand-held power tools should be equipped with highly sensitive action leakage protectors.

7) The power cords of portable power tools and hand-held power tools must use copper core multi-strand rubber sheathed flexible cables or PVC sheathed flexible cables. The cables should avoid heat sources and should not be dragged on the ground. When the above requirements cannot be met, measures should be taken to prevent heavy objects from crushing the cable.

8) When mobile power tools and hand-held power tools need to be moved, do not carry the power cord or rotating parts.

9) After the use of portable power tools and hand-held power tools, the power supply must be disconnected on the power supply side.
