Makita DA391D Problems and Solutions

The Makita DA391D is a powerful and versatile impact wrench, but it can develop some common problems over time. Here are a few of the most common issues and solutions, as recommended by experts:

• The impact wrench won't turn on. This is usually caused by a dead battery. Make sure the battery is fully charged, or try replacing it with a new one.

• The impact wrench is making a loud noise. This could be a sign of a bearing problem. If the noise is accompanied by vibration, it's definitely time to take the impact wrench in for repairs.

Try cleaning the air filter and replacing the impact socket. If the problem persists, you may need to take the impact wrench in for repairs.
• The impact wrench is leaking oil. This is a serious problem that should not be ignored. Oil leaking from the impact wrench can damage the internal components and may even cause a fire.
