Makita GA5020 Problems and Solutions
some common problems with the Makita GA5020 angle grinder and their solutions:
Problem: The angle grinder is not spinning at a constant speed or is slower than normal.
Solution: This is most likely due to worn carbon brushes. The carbon brushes are two pieces of an electric motor that transmit current to the rotating armature via the commutator. Worn carbon brushes can decrease the overall performance of the motor. To replace the carbon brushes, follow these steps:
- Unplug the angle grinder from the power outlet.
- Remove the two screws that hold the brush cover in place.
- Remove the brush cover.
- Inspect the carbon brushes. If they are worn down to less than 1/8 inch, they need to be replaced.
- To replace the carbon brushes, simply push them out of the brush holders and insert new ones.
- Reinstall the brush cover and tighten the screws.
- Plug the angle grinder back in and test it to make sure it is spinning at a constant speed.
Problem: The angle grinder is not turning on.
Solution: This could be due to a number of reasons, including a blown fuse, a faulty switch, or a loose connection. To troubleshoot this problem, follow these steps:
- Check the fuse. If the fuse is blown, replace it with a new one.
- Check the switch. If the switch is faulty, it will need to be replaced.
- Check the connections. Make sure that all of the connections are tight.
Problem: The angle grinder is sparking.
Solution: This is usually caused by worn carbon brushes. As the carbon brushes wear down, they can create sparks. To fix this problem, follow the steps above to replace the carbon brushes.
Problem: The angle grinder is overheating.
Solution: This is usually caused by prolonged use at high speeds. To prevent the angle grinder from overheating, allow it to cool down for a few minutes before using it again. You can also try using a lower speed setting.
If you are unable to fix the problem with your Makita GA5020 angle grinder, you may need to take it to a qualified technician for repairs.
