Circular saws usually stall due to a dull or damaged blade. But issues like an insufficient battery or a damaged power cord can also cause a circular saw to stall over and over again.

As I mentioned before, the problem can be caused by many reasons. So there is no single answer to the above question i.e. h “Why does mine workSierra circularkeep stopping?"

Luckily I have already done some research for you. During my studies I found a few reasons that cause a circular saw to stall or behave strangely.

Why does my circular saw keep stalling? 9 reasons and solutions - excellent cutter (1)

Reason 1: Blade problem

As I mentioned earlier, the first and most common problem due to it being aCircular saw keeps stopping when the saw blade is damaged. You should check each time before you want to use your saw.

Always make sure you have a blade in good condition before cutting anything with it. This way the machine is not put under too much stress and the saw can work properly without putting too much stress on it.

Reason 2: Poor Performance

If the saw you are using does not have enough power to cut through an object, it will not be able to cut and will stall. most ofCircular saws that come with a 7-1/4-inch bladeconsume about 65 watts of power.

However, some models require up to 80 watts. So make sure your saw has enough power to cut through the material you're trying to cut. The knife will stop until it receives enough power.

Reason 3: insufficient weight

Similarly, if your saw isn't heavy enough, it won't be able to provide enough torque to cut through the material and will stall constantly. To find out how much weight your circular saw should weigh, consider whether you are cutting soft material (wood) or hard material (plastic).

If you need more weight for a circular saw, choose a model that has a metal plate next to the saw blade. If you plan to cut a large number of similar materials, choose a heavy-duty circular saw.

Reason 4: loose power cord

If the power cord is not connected correctly, it continues to stop. You need to make sure you have a solid connection between the circular saw and the outlet.

While cutting with your circular saw, check if the wires are still connected correctly or not. If you find a loose wire or connection, simply stop the circular saw and rearrange the wires so there is a proper connection.

Reason 5: damaged power cord

If your power cord becomes damaged or burned while cutting, it can also cause your circular saw to stall constantly. Using a concrete blade when working on concrete surfaces can very easily damage the power cord.

Also, the shield that came with your saw is not made of a soft material and cannot withstand high temperatures. So if you're working on a hot surface like concrete, the laser will glow red in no time, which can also damage the power cord.

Similar problems can also cause a circular saw to keep stalling. So make sure your power cord isn't damaged or that you have an extension cord that can handle the heavier load of your jobsite and keep the saw running smoothly.

Reason 6: Motor problems

The other reason a circular saw stalls is motor problems. If there is a problem with the motor, it can cause your saw to stall or not run properly.

The best way to tell if there is a problem with your circular saw motor is to check the blade tension while you are cutting. If you feel the blade is loose or not holding properlycut a straight lineline, there is most likely a problem with the motor.

To resolve this issue you can either clean the gears with a lubricant or there are some small parts that may need to be replaced to get your saw working properly again.

Reason 7: Bad connection

If there is a bad connection between the handle (where you connected the battery) and the saw blade, it can also cause your saw to stall constantly.

To ensure a tight connection, make sure you have firmly inserted the screws (provided with your saw) and tighten them with a screwdriver.

This holds the battery in place so it doesn't move out of position while cutting, causing the circular saw to stop suddenly over and over again.

Reason 8: The motor does not work properly

The other reason your circular saw keeps stalling is that your saw's motor may not be running properly. If your corded circular saw is having a motor problem, see how often it stalls while cutting wood.

If there are multiple interruptions while cutting a board, the motor is most likely not working properly. In this case, you must repair or replace the motor of your circular saw.

Or if there are no breaks at all, your power cord may be damaged, and as mentioned above, you can easily replace it with a heavy-duty one.

Reason 9: sawdust

The last reason for your circular saw to stop suddenly is dust buildup in your motor. When the motor is clogged with sawdust and dirt, not enough air or cooling can get to the motor area. This will cause your engine to overheat and stop running out of the blue.
