DeWalt DHS790AB Problems and Solutions

The DeWalt DHS790AB is a powerful and versatile miter saw, but it can experience some common issues. Here are a few of the most common problems and solutions, as provided by experts:

Problem: The saw won't start. Solution: Check to make sure that the saw is plugged in properly and that the battery is charged. If the saw still won't start, check the circuit breaker or fuse. If those are okay, then the brushes may need to be replaced.

Problem: The saw is making a loud noise. Solution: This could be caused by a number of things, such as a loose blade, a misalignment of the blade, or a worn-out bearing. To troubleshoot the noise, start by checking the blade. If it's loose, tighten it. If it's not loose, then check the alignment of the blade. If the blade is misaligned, then adjust it. If the blade is aligned correctly, then the noise is likely coming from a worn-out bearing. In this case, you'll need to replace the bearing.

Problem: The saw is not cutting accurately. Solution: This could be caused by a number of things, such as a dull blade, a misalignment of the blade, or a worn-out fence. To troubleshoot the accuracy of the saw, start by checking the blade. If the blade is dull, then sharpen it. If the blade is not dull, then check the alignment of the blade. If the blade is misaligned, then adjust it. If the blade is aligned correctly, then the problem is likely with the fence. In this case, you'll need to adjust the fence or replace it.

Problem: The saw is overheating. Solution: This could be caused by a number of things, such as a dirty blade, a high-friction cut, or a worn-out motor. To troubleshoot the overheating of the saw, start by checking the blade. If the blade is dirty, then clean it. If the blade is not dirty, then check the cut. If the cut is high-friction, then try to reduce the friction. If the cut is not high-friction, then the problem is likely with the motor. In this case, you'll need to replace the motor.

Recall: In 2019, DeWalt issued a recall for the DHS790AB miter saw due to a potential fire hazard. If you have a DHS790AB miter saw, you should contact DeWalt to see if your saw is affected by the recall. If it is, DeWalt will replace your saw free of charge.
