DeWalt DW400 Problems and Solutions

Sure. Here are some common issues and problems with the DeWalt DW400 angle grinder, along with expert-recommended solutions:

Issue: The grinder starts smoking. Solution: This is usually caused by overheating. Allow the grinder to cool down completely before using it again. If the problem persists, you may need to replace the brushes.

Issue: The grinder is not spinning. Solution: Check the power cord to make sure it is plugged in properly. If the cord is plugged in and the grinder is still not spinning, the switch may be faulty. You can try cleaning the switch contacts with a contact cleaner. If that does not work, you may need to replace the switch.

Issue: The grinder is making a loud noise. Solution: This could be caused by a number of things, such as worn bearings, a loose nut, or a damaged blade. Check the grinder for any obvious signs of damage. If you cannot find the source of the noise, you may need to take it to a qualified technician for further diagnosis.

Issue: The grinder is not cutting through material as easily as it used to. Solution: This could be caused by a dull blade. Sharpen the blade or replace it with a new one. You may also need to adjust the wheel guard to ensure that it is not interfering with the cutting action.

Issue: The grinder is not breaking sparks. Solution: This is usually caused by a dirty or damaged carbon brush. Clean the brushes with a wire brush or replace them if they are damaged. You may also need to adjust the brush gap.

Issue: The grinder is not spinning in reverse. Solution: This is usually caused by a faulty switch. You can try cleaning the switch contacts with a contact cleaner. If that does not work, you may need to replace the switch.
