Why does my circular saw keep stopping?


Rough Saw Blades

The most common issue that you can easily detect with a circular saw is with the blade. If a blade works smoothly and stops working, you should check the blade to see the state or condition of the teeth. If the blade turns out to be edgeless or rough, it is clear that the blade will never work.

Overloading The Saw

Some machine dares to handle any condition as they have the design to keep all situation under control. But for a circular saw that doesn’t have this feature, once overheating takes place, the machine is expected to malfunction.

Once the machine gets overloaded, it will not work because it requires certain pressure to cut through anything. So, the thermal switch will stop the blade from working once it overheats.

Motor Issues

One other reason your machine can stop working is when the motor gets faulty. The motor triggers the command that makes the engine work, and once it has an issue, it is never going to work.
