Electric tools remind you to use electric motors or electromagnets as power, and a mechanized thing that drives the working head through a transmission arrangement is called an electric thing. Electric tools are mainly divided into metal cutting electric tools, grinding electric tools, device electric tools and railway electric tools. The most common electric tools are electric drills, electric grinders, electric wrenches and electric screwdrivers, electric hammers and impact drills, concrete vibrators, and electric planers. The power socket must match the power plug of the electric appliance. Do not innovate the power plug under any circumstances. Do not operate any socket with a common ground. Unmodified plugs and suitable sockets can increase the risk of electric shock. Keep the equipment away from rain and humid environments. Water entering electric objects will increase the risk of electric shock. Such as when lifting, hanging things, or unplugging the plug from the socket. Please use a late power cord that is approved for outdoor use. Operating a late power cord suitable for outdoor use can reduce the risk of electric shock when you operate electric things outdoors. Stay awake. And control the electric policy calmly. When you are decadent or under the influence of narcotics, alcohol, or drugs, please do not operate the electric policy. The momentary breakup of attention when operating an electric tool may cause serious danger.
