How to Check the Mains Supply for Makita Tools
If you own a Makita tool and are having issues with it not working properly, one of the first things to consider is whether your mains supply is functioning correctly. Checking the mains supply is essential to ensure your tool operates safely and efficiently. Here’s what you need to know. Power Supply Requirements
Makita tools, specifically those designed for heavy work like chiseling and demolition, should be connected to a power supply that matches the voltage indicated on the nameplate of the tool. They require a single-phase AC supply and can be used with sockets that do not have an earth wire due to their double insulation. Voltage Range
Ensure your mains supply is between 220 V and 250 V. Important Factors
Voltage Fluctuations: Operating a Makita tool under unstable voltage can negatively affect both the tool and other equipment connected to the mains. It’s crucial that the mains impedance is equal to or less than 0.31 Ohms to prevent problems.

Protection Mechanism: Make sure that the mains socket you use is equipped with a fuse or a protective circuit breaker that has slow tripping characteristics, which can help prevent electricity spikes from damaging your tools. Identifying Mains Supply Issues
Before troubleshooting, it’s good practice to follow these steps to check the mains supply:
Check the Indicator Lamp: When you plug in your Makita tool, the power-ON indicator lamp should light up. If the lamp is lit, but the tool does not start, possible causes include worn-out carbon brushes or defects in the motor or switch. Troubleshoot the Power Source:
If the lamp does not turn on, the mains cord or the lamp itself could be faulty. Plug another working appliance into the same socket to ensure that the socket is live and functioning. Inspect the Mains Cable: Look for any signs of wear or damage on the cord and plug. A faulty cord can cause intermittent power loss. Testing the Voltage
If you have a multimeter:
Set the multimeter to read AC voltage. Insert the probes into the live and neutral ports of your wall socket. Confirm that the reading falls within the required range of 220 V to 250 V.

If the voltage is too low or too high, you may need to contact an electrician to resolve the issue. Effects of Poor Mains Supply
Using your Makita tool with an inappropriate power supply can lead to:
Tool Malfunction: Consistent use under poor conditions may cause damage to the tool’s motor or internal components. Safety Hazards: Improper voltage can increase the likelihood of electric shock or fire hazards. Maintaining Your Tool’s Performance
Regular maintenance and careful power checks can extend the life and efficiency of your Makita tools. Here are a few tips:
Regularly check the condition of carbon brushes. Keep the environment free of moisture, as water can damage electrical components. Always use Makita-approved accessories to avoid compatibility issues. Conclusion
Checking the mains supply of your Makita tool is a crucial step in ensuring its longevity and your safety. By following these steps, you can troubleshoot common issues related to the power supply. If you continue to experience problems, consider seeking assistance from a professional or contacting a Makita service center. Remember, safe operation begins with a reliable power source!
