Dewalt Circular Saw Flashing Light: 5 Indications

One of the most common problems users face with Dewalt is grasping the flashing light signals. Figuring out which specific light indicates which signals can be quite confusing and complicated.

So what does Dewalt Circular Saw Flashing Light actually point out?

For starters, the Dewalt charger has LED indicators, and each of these lights has a distinct function. When there is a blinking red light, it directs that it is in charging mode. Until the battery reaches its maximum capacity you should not unplug the charger.

However, that was just a brief introduction to the flashing light signals of the Dewalt Circular Saw. We have articulated a more in-depth article to cover all the basics and instructions.

To clear your confusion and to make this easier, let’s jump right into it.

What Does Flashing Light on Dewalt Circular Saw Indicate?

Dewalt has a wide range of popularity for its tools all over the world. You might want to look into the quality of  dewalt hand tools if you’re having second thoughts.


It can get quite difficult and frustrating while figuring out the Dewalt Circular Saw manual. Big issue users encounter is not understanding the various Dewalt LED indications. As a result, they cannot take the right step needed accordingly at the right time.

Here are the 5 situations you can face with Dewalt Circular Saw flashing light:

While Charging

A blinking red light indicates the battery needs to be charged if you plug in the charger. It’s quite similar to Dewalt 20V flashlight blinks. You have to leave it on the charger and don’t remove it until it is fully charged. 

You can remove it once the light turns green. It means the battery is fully charged now.


You might wonder if a fully charged battery shows green when the charger is plugged in.

But, here’s a catch-

In such a case, the battery will show a constant red light that does not blink. When the battery is fully charged or unchargeable, it puts on a constant red light. It indicates that you need to remove the charger immediately.

Hot/Cold Pack Delay

When the battery gets overheated or too cold, the charger starts a Dewalt Hot/Cold Pack Delay. It starts on its own by default. The red light will keep on blinking, but a yellow indicator light will also show up.

The charging is discontinued until the battery has reached the optimum temperature.

Once the appropriate temperature has been achieved, the yellow light will set off. And the charging procedure will be resumed.

The charger then turns on the pack charging mode automatically. Longevity and quality of battery life is ensured through this feature.

A warm battery pack charges at a faster pace than a cold battery pack. The cold battery pack will charge slowly throughout the entire charging cycle. And maximum charge rate won’t be obtained even if the battery gets warm.


Faulty Battery Pack

If the charger detects a faulty battery pack it will automatically stop charging. The charger will indicate a faulty battery by flashing or blinking the Dewalt battery indicator light very fast.

Due to poor connection between the battery and charger, fast flashing of light is observed. It can also indicate that there is a problem with the battery pack. 

The battery needs to be removed from the charger. You can clean the metal contact terminals on the battery with a clean cloth. And check if the condition is fixed by trying to charge the battery again.

However, if the charger still keeps flashing fast that means the condition is not fixed. Hence Dewalt Circular saw troubleshooting won’t be enough at that moment. In such cases, you will need to replace the battery pack.

Problem with the Powerline

If there is a problem with the powerline, the charger will keep flashing too fast at a time. You need to check if the wires are properly connected or not. Also, check out the internal settings to find out if everything is functioning correctly.

These are the conditions you needed to know about what a Flashing light on a Dewalt circular saw meant.

Why does my Dewalt circular saw stop working?

Typically, a circular saw stops due to the blade getting stuck in wood or material. As a result, the blade can’t penetrate the material due to its insufficient power. This could also be caused by the blade breaking or by a malfunctioning motor.

Why does my Dewalt circular not cut?

Ensure that your workpiece is getting the required support it needs. Because it can pinch the blade which results in kickback in addition to stopping. Warped, bent, dull, or damaged blades can lead to your saw not cutting. A faulty motor or overheated machine can also stop your saw from cutting. 

How do you unlock a Dewalt circular saw?

You will find a small knob located in the miter saw from the top. It helps to keep the head locked when the whole machine is in storage. To unlock, simply turn the knob until the head moves. It will be unlocked in a jiffy.
