What should I pay attention to when using power tools?

1. Before using the tool, the full-time electrician should check whether the wiring is correct and prevent the accident caused by the misconnection of the neutral line and the phase line.

2. If the tool that has not been used for a long time or is damp is used, the electrician should measure whether the insulation resistance value meets the requirements before use.

3. The flexible cable or cord that comes with the tool must not be connected. When the power supply is far away from the work site, it should be solved by using the mobile power box.

4. The original plug of the tool must not be removed or changed at will. It is strictly forbidden to directly insert the wire of the wire into the socket without using the plug.

5. The tool case is found and the handle is broken. It should be stopped and replaced.

6. Non-professional personnel shall not disassemble and repair tools without authorization.

7. The rotating parts of the tool should have guards.

8. The operator wears protective protective equipment as required.

9. At the power supply, the leakage protector must be installed.
