Changing the blade on your Makita circular saw is a simple process that any DIYer or professional can do. Whether you need to replace a worn-out blade or switch to a different type of blade for a specific task, this guide will walk you through the steps to ensure a safe and successful blade replacement.
Step 1: Gather the Necessary Tools
Before starting the blade replacement, make sure you have all the necessary tools on hand. You will need a wrench or Allen key (depending on your Makita saw model), a workbench or sturdy surface, and a new blade that matches the specifications of your saw.
Step 2: Disconnect the Power Source
The safety of any power tool operation is of utmost importance. Before changing the blade, disconnect the saw from its power source to prevent any accidental starting or electric shocks. If your saw is corded, unplug it from the wall outlet. For cordless saws, remove the battery.
Step 3: Secure the Blade
Place the saw on a workbench or sturdy surface with the blade facing upwards. To secure the blade, use the provided blade wrench or Allen key to lock the arbor and prevent it from rotating. The arbor is the part that holds the blade in place.
Step 4: Remove the Blade Nut
With the arbor secured, use the wrench or Allen key to loosen and remove the blade nut in a counterclockwise direction. Place the nut in a safe place where it won’t get lost.
Step 5: Replace the Blade
Carefully lift the old blade off the arbor and set it aside. Take the new blade that matches the specifications of your saw and slide it onto the arbor, making sure it aligns with the blade guide. Once properly aligned, tighten the blade nut in a clockwise direction using the wrench or Allen key.
Step 6: Test the Blade
After securing the new blade, give it a gentle spin by hand to ensure it rotates freely and smoothly. This step is important to make sure the blade is properly installed and won’t malfunction during operation.
Step 7: Reconnect the Power Source
Finally, once you have confirmed that the new blade is securely in place, reconnect the saw to its power source. If your saw is corded, plug it back into the wall outlet. For cordless saws, reinsert the battery.
Note: It is always recommended to consult the user manual specific to your Makita saw model for any additional instructions or safety precautions regarding blade replacement.
With these easy steps, you can confidently replace the blade on your Makita circular saw and continue tackling your woodworking projects with precision and efficiency!

Gather Necessary Tools and Safety Equipment
Before attempting to replace the blade on your Makita circular saw, it is important to gather all of the necessary tools and safety equipment. This will ensure that you have everything you need to safely and efficiently complete the task. Here are the tools and safety equipment you will need:
Tools:
- A replacement blade suitable for your Makita circular saw
- An adjustable wrench or blade wrench
- A screwdriver (if required for your specific saw model)
- A workbench or sturdy surface to secure the saw
Safety Equipment:
- Safety glasses or goggles
- Heavy-duty gloves
- Ear protection (such as earplugs or earmuffs)
- A dust mask (if cutting materials that may produce airborne particles)
Having all of these tools and safety equipment on hand will help ensure that you can work safely and efficiently. It is important to always follow safety precautions and use the appropriate tools for the job to prevent accidents or injury.
Disconnect Power and Remove Old Blade
Before starting any work on your Makita circular saw, it is essential to disconnect the power source to ensure your safety. Make sure the saw is turned off and unplugged from the power outlet.
Once you have confirmed that there is no power running to the saw, you can proceed with removing the old blade. Begin by locating the blade lock button, which is usually located near the blade housing.
Press and hold down the blade lock button to keep the blade from rotating while loosening the bolt that secures it. Use a wrench or a socket wrench, depending on the model of your saw, to turn the bolt counterclockwise.
Once the blade bolt is loose, carefully remove it and any washers or spacers that may be attached to it. Be sure to keep track of the order in which the washers and spacers are removed, as this will help you reassemble the saw correctly later on.
Next, release the blade lock button and gently lift the old blade out of the blade housing. Set it aside in a safe place or dispose of it properly according to local regulations.
You have now successfully disconnected the power and removed the old blade from your Makita circular saw. Proceed to the next step to learn how to install a new blade.
Prepare and Install New Blade
Before replacing the blade on your Makita circular saw, it is important to ensure that you have the necessary tools and take proper safety precautions. Follow these steps to prepare and install a new blade:
- Disconnect the circular saw from the power source to prevent any accidental starts.
- Place the circular saw on a flat and stable surface, such as a workbench or table.
- Loosen the blade guard by turning the blade guard release lever counterclockwise. Carefully lift the blade guard to expose the old blade.
- Use a wrench to loosen the bolt or nut that holds the old blade in place. Turn the bolt or nut clockwise to loosen it. Remove the bolt or nut and set it aside.
- Remove the old blade by sliding it out from the blade housing. Be cautious of the sharp teeth and edges.
- Inspect the new blade for any damage or defects. Make sure it is the correct size and type for your circular saw.
- Slide the new blade into the blade housing, ensuring that the teeth are facing in the direction of rotation indicated on the saw.
- Secure the new blade by tightening the bolt or nut with a wrench. Turn the bolt or nut counterclockwise to tighten it.
- Lower the blade guard back into place and secure it by turning the blade guard release lever clockwise.
- Double-check that the blade is securely installed and the blade guard is properly positioned.
Once you have completed these steps, you are ready to connect the circular saw back to the power source and continue with your cutting tasks using the new blade.
Reconnect Power and Test the Circular Saw
Once you have successfully replaced the blade on your Makita circular saw, it’s time to reconnect the power and test it to ensure it’s working correctly. Follow these steps to reconnect the power and test the saw:
- Double-check that the power source is disconnected to ensure your safety.
- Plug the power cord back into the appropriate outlet or power source.
- Position the circular saw in a safe and stable location.
- Make sure the blade guard is in the proper position and functioning correctly.
- Press the power button or trigger to turn on the circular saw.
- Listen for any abnormal sounds or vibrations that could indicate an issue.
