When it comes to maintaining your Makita circular saw, one important aspect to consider is changing the brushes. The brushes in your circular saw are responsible for transferring electricity to the motor, allowing it to function properly. Over time, the brushes can wear down and need to be replaced. In this guide, we will walk you through the steps to change the brushes on your Makita circular saw, ensuring its optimal performance.
Step 1: Preparation
Before you begin, make sure the circular saw is disconnected from any power source. This is crucial to ensure your safety during the process. Additionally, prepare the necessary tools, including a small screwdriver and replacement brushes specifically designed for your Makita circular saw model.
Pro tip: It is ideal to have a spare set of brushes on hand so you can quickly replace them when needed, without interruptions to your work.
Step 2: Opening the Motor Housing
Locate the screws that secure the motor housing of your circular saw. Use the small screwdriver to remove these screws, allowing you to access the motor compartment. Take caution while performing this step, as dropping any loose screws could result in damage to your saw.
Pro tip: It may be helpful to place a cloth or towel beneath the saw to catch any loose screws and prevent them from rolling away.
Step 3: Removing the Old Brushes
Once the motor compartment is accessible, you will see the brushes attached to the motor. Gently remove the brush caps, usually held in place by a small spring or clip. Carefully take out the old brushes, ensuring not to damage any surrounding components.
Pro tip: Take note of the orientation of the old brushes before removing them, as the new brushes must be installed in the same position.
Step 4: Installing the New Brushes
Take out the replacement brushes from their packaging and insert them into the motor compartment, aligning them correctly. Make sure the brush caps fit snugly over the new brushes, securing them in place. Double-check that the brushes are in the correct position, and that they are making proper contact with the motor.
Pro tip: Gently wiggle the brushes to ensure they are seated properly before reassembling the motor housing.
Step 5: Reassembling the Motor Housing
With the new brushes properly installed, carefully reattach and tighten the screws to secure the motor housing back in place. Ensure all screws are tightened securely, but avoid over-tightening, as this can cause damage to the housing or other components.
Pro tip: Once reassembly is complete, take a moment to inspect the rest of the circular saw for any signs of wear or damage. Address any other maintenance tasks that may be necessary to keep your saw in optimal condition.
In conclusion, changing the brushes on your Makita circular saw is a relatively simple task that can greatly extend the lifespan and performance of your tool. By following these steps and regularly maintaining your saw, you can ensure it continues to deliver accurate and efficient cutting results for years to come.

Turn Off and Unplug the Saw
Before you begin changing the brushes on your Makita circular saw, it is important to ensure that the tool is completely turned off and unplugged. This will help prevent any accidents or injuries while working on the saw.
To turn off the saw, locate the power switch on the tool. It is typically located on the side or near the handle of the saw. Slide the switch to the “Off” position to shut off the power.
Once the saw is turned off, unplug it from the power source. If the saw is corded, simply disconnect it from the wall outlet. If the saw is cordless, remove the battery pack from the tool.
By turning off and unplugging the saw, you eliminate the risk of accidentally starting the saw while you are changing the brushes. This simple precaution can help ensure your safety and the success of your brush change.

Locate the Brush Caps
Changing the brushes on a Makita circular saw is a straightforward process. Before you start, ensure that the saw is unplugged and the blade is disengaged.
Begin by locating the brush caps, which are usually located on the sides of the saw motor. These caps cover the carbon brushes, which are essential for providing electrical connections to the motor. The brush caps are typically circular in shape and can be made of plastic or metal.
Note: Some models have brush caps on both sides of the motor, while others may have just one brush cap. Check your saw’s user manual or the manufacturer’s website for specific instructions for your model.
Once you have located the brush caps, use a flathead screwdriver or a coin to unscrew and remove them. Be careful not to lose the screws as you will need them when reinstalling the caps.
Tip: If the brush caps are difficult to remove, try using a pair of pliers or an adjustable wrench to get a better grip.
With the brush caps removed, you will be able to see the carbon brushes. These small, rectangular blocks are usually black in color and sit snugly against the motor’s armature. Carefully inspect the brushes for any signs of wear or damage. If the brushes appear excessively worn or have a chipped or frayed edge, it is time to replace them.
Caution: Do not touch the motor’s armature or attempt to remove it. This can lead to damage and could result in an unsafe operation of the saw.
If the brushes need to be replaced, carefully lift them out of their holders. Take note of their orientation and how they are positioned inside the holder, as you will need to install the new brushes in the same manner.
Replacing the brushes and reinstalling the brush caps will be covered in separate sections. Please refer to the appropriate instructions to continue with the brush change process.
Remove the Brush Caps
To change the brushes on your Makita circular saw, you’ll need to start by removing the brush caps. These caps cover the brushes and are located on either side of the saw’s motor.
Using a small flathead screwdriver, gently pry off the brush caps. Be careful not to damage them as you remove them.
Once the brush caps are removed, you’ll be able to see the brushes underneath. Take note of the orientation of the brushes and their springs, as you’ll need to reinstall them correctly later.
With the brush caps removed, you can now access the brushes and replace them if necessary. Check the condition of the brushes – if they’re worn down or damaged, it’s time to replace them.
To remove the brushes, gently pull them straight out. Be careful not to twist or bend them excessively, as this can cause damage.
After removing the old brushes, it’s a good idea to clean the brush holders and the surrounding area. Use a small brush or compressed air to remove any dust or debris.
Now that the brush caps are removed and the old brushes have been taken out, you’re ready to install the new brushes. Insert the new brushes into the brush holders, making sure they fit securely and are oriented correctly.
Once the new brushes are in place, you can reinstall the brush caps by pressing them firmly back into position. Make sure they are fully seated and secure.
With the brush caps back in place, your Makita circular saw is now ready for use with its new brushes installed. Remember to periodically check and replace the brushes as needed to ensure optimal performance.
