DeWalt DCS391 Problems and Solutions

The DeWalt DCS391 cordless circular saw is a popular tool for DIYers and professionals alike. However, like any tool, it can experience problems from time to time. Here are some common issues and solutions for the DeWalt DCS391:

Saw blade not spinning: If the saw blade doesn't spin, the first thing to check is the battery. Make sure that the battery is properly inserted and that the battery is charged. If the battery is inserted correctly and is fully charged, then the next step is to check the saw's trigger switch. Make sure that the switch is in the "on" position. If the switch is in the "on" position and the saw blade still doesn't spin, then the problem may be with the saw's motor. If the motor is faulty, it will need to be replaced.
Saw blade binding: If the saw blade binds, it is usually caused by the saw blade being dull or the wood being too thick. To fix this, try sharpening the saw blade or using a thinner piece of wood. If the saw blade is still binding, then the problem may be with the saw's alignment. If the saw is not aligned properly, it will need to be adjusted.
Saw blade wobbling: If the saw blade wobbles, it is usually caused by the saw blade being loose or the saw's arbor nut being tightened too much. To fix this, tighten the saw blade or loosen the arbor nut. If the saw blade is still wobbling, then the problem may be with the saw's arbor. If the arbor is damaged, it will need to be replaced.

If you are experiencing any of these problems with your DeWalt DCS391, it is best to consult with a professional to diagnose and fix the problem.

Here are some additional tips to help you prevent problems with your DeWalt DCS391:

Use the right saw blade for the job: Make sure that you are using the correct saw blade for the material you are cutting. For example, if you are cutting wood, you should use a wood-cutting saw blade.
Keep the saw blade sharp: A sharp saw blade will cut more smoothly and reduce the risk of binding.
Lubricate the saw: The saw's motor and arbor should be lubricated regularly to prevent wear and tear.
Store the saw properly: When you are not using the saw, store it in a safe place where it will not be exposed to moisture or extreme temperatures.
