Makita 4390D Problems and Solutions

Sure. Here are some common issues and problems with the Makita 4390D and their solutions:

• The saw does not start. This is usually caused by a problem with the trigger switch. To fix this, you can try cleaning the switch with contact cleaner. If that does not work, you may need to replace the switch.
• The saw blade is not spinning. This can be caused by a problem with the motor, the belt, or the blade itself. To troubleshoot this issue, you can try checking the motor for any obvious problems, such as loose wires or burned-out components. You can also try tightening the belt or replacing the blade.
• The saw blade is not cutting straight. This can be caused by a number of factors, such as a dull blade, a warped fence, or an incorrect cutting angle. To fix this issue, you can try sharpening the blade, adjusting the fence, or changing the cutting angle.
• The saw is making a strange noise. This could be a sign of a more serious problem, such as a bearing or motor issue. If you hear a strange noise coming from your saw, it is best to stop using it and have it serviced by a qualified technician.
