Hardware knowledge: precautions for the operation of hardware power tools

Hardware power tools are products that are often used in modern industrial industries. They generally use electricity as the driving force. However, some things need to be paid attention to during use. What matters should operators pay attention to when using power tools?

Precautions for the operation of electric tools:

1. Before using the tool, a full-time electrician should check whether the wiring is correct to prevent accidents caused by the wrong connection of the neutral line and the phase line.

2. Before using the tools that have been left unused or damp for a long time, an electrician should measure whether the insulation resistance meets the requirements.

3. The flexible cable or cord that comes with the tool must not be extended. When the power source is far away from the work site, a mobile switch box should be used to solve it.

4. The original plug of the tool shall not be removed or changed at will. When the original plug is damaged, it is strictly forbidden to directly insert the wire of the wire into the socket without the plug.

5. If the shell and handle of the tool are found to be broken, stop using it and replace it.

6. Non-full-time personnel are not allowed to disassemble and repair tools without authorization.

7. The rotating parts of the holding tool should have protective devices.

8. Operators wear insulating protective equipment (insulating shoes, insulating gloves, etc.) as required.

9. A leakage protector must be installed at the power source.

10. It is strictly forbidden to use it with overload, pay attention to the sound and temperature rise, and immediately stop the machine for inspection if any abnormality is found.
