Makita HR140DWMJ Problems and Solutions

The Makita HR140DWMJ is a popular cordless hammer drill, but it can experience some common problems. Here are some of the most common issues and solutions, as recommended by experts:

  • The drill won't turn on. This is usually caused by a dead battery. Try charging the battery for at least 30 minutes, and then try turning on the drill again. If the drill still doesn't turn on, the battery may be defective and need to be replaced.
  • The drill won't drill through concrete. This is usually caused by the drill bit not being sharp enough. Try sharpening the drill bit, or using a different drill bit that is designed for concrete. You may also need to apply more pressure to the drill.
  • The drill chuck is loose. This can cause the drill bit to wobble and make it difficult to drill straight. To tighten the chuck, use a wrench to turn the chuck tightening screw clockwise.
  • The drill overheats. This is usually caused by the drill being used for too long at a high setting. Allow the drill to cool down before using it again. You may also want to try using a lower setting.

If you are experiencing any other problems with your Makita HR140DWMJ, you can consult the owner's manual for more troubleshooting tips. You can also contact Makita customer support for assistance.
