Why doesn’t my power tool work even though it’s connected to the power source?

There are several possible reasons why your power tool is not working despite being connected to a power source. Here are the four most common:

• Faulty power source: There may be a problem with the power source. Check whether the socket is working by plugging in another device. For battery-powered tools, make sure the battery is inserted correctly and has enough charge.
• Problem with the switch: The tool’s switch may be defective or blocked by dirt and dust. Try operating the switch several times or cleaning it.
• Internal wiring issues: The tool’s internal wiring may be damaged. This is more common in older or heavily used tools. In this case, you may need professional repair assistance.
• Damaged motor brushes: The brushes in the motor may be worn out. These can often be replaced yourself; make sure you use the correct model.

Please remember that the utmost caution should always be exercised when carrying out any repairs on power tools. If you are unsure, consult a professional.
