Changing the blade on your Makita circular saw is a crucial maintenance task that ensures your tool operates efficiently and safely.

Whether you’re a seasoned craftsman or a DIY enthusiast, understanding how to replace the blade properly can save time and reduce the risk of accidents. This guide on how to change a blade on a makita circular saw will walk you through each step of the process, providing clear instructions and helpful tips to make the blade-changing procedure as straightforward as possible.

Why Change the Blade?

Before diving into the steps of changing a blade, it’s essential to understand why this task is necessary. Over time, circular saw blades can become dull and worn out from frequent use. A dull blade not only slows down your work but also increases the risk of accidents due to kickback or binding. Additionally, using a dull blade will result in poor-quality cuts, affecting the overall outcome of your project. Regularly changing the blade on your Makita circular saw ensures that you’re working with a sharp cutting surface, making for smoother and safer operation.

What You Will Need

To change the blade on your Makita circular saw, you will need the following tools and materials:

A New Blade Suitable for Your Makita Circular Saw:

Before purchasing a new blade, make sure it is compatible with your specific Makita circular saw model. Check the size and type of blade recommended by the manufacturer to ensure a proper fit.

Safety Gear:

Safety should always be a top priority when working with power tools. Wear protective gear such as safety goggles, gloves, and hearing protection while changing the blade on your Makita circular saw.

Wrench or Allen Key:

Most Makita circular saws come with a wrench or an Allen key for loosening and tightening the blade bolt.

7 Steps on How to Change a Blade on a Makita Circular Saw

Step 1: Unplug the Saw

Before you begin the blade-changing process, it is imperative to ensure your safety by disconnecting the power source.

Unplug your Makita circular saw from the electrical outlet to prevent any accidental start-up while you are handling the blade. If you are using a cordless model, remove the battery completely.

Taking this precautionary step eliminates the risk of electrical shock and accidental activation, creating a safe environment to proceed with the blade change.

Step 2: Remove the Blade Bolt

With the saw safely unplugged or the battery removed, locate the blade bolt situated at the center of the blade.

Using the wrench or Allen key provided with your Makita circular saw, turn the blade bolt counterclockwise to loosen it. On some models, you might need to press and hold the spindle lock button to prevent the blade from rotating as you turn the bolt.

Carefully remove the blade bolt and set it aside in a safe place. This step is crucial as it allows the blade to be freed from the saw, preparing it for the installation of the new blade.

Step 3: Remove the Old Blade

After loosening and removing the blade bolt, gently pull the outer washer off the spindle and set it aside with the bolt.

With the washer removed, you can now slide the old blade off the spindle. Be cautious while handling the blade, as the teeth may still be sharp. If the blade feels stuck, wiggle it slightly to loosen it, but avoid using excessive force.

Once the blade is free, carefully lift it away from the saw and place it aside for proper disposal or sharpening, if necessary.

This step completes the removal process, making way for the installation of the new blade.

Step 4: Clean the Saw and Install the New Blade

Before installing the new blade, take a moment to clean any dirt or debris from the saw’s surface, especially around the spindle area. This step ensures that the new blade is installed on a clean and flat surface for optimal performance.

Once cleaned, align your new blade with the spindle and carefully place it onto the saw until it rests against the inner washer.

Step 5: Reattach the Washer and Blade Bolt

With the new blade securely in place, the next step is to reattach the outer washer and blade bolt.

Begin by placing the outer washer back onto the spindle, ensuring it sits flush against the blade. This helps hold the blade firmly in position. Next, take the blade bolt that you set aside earlier and insert it through the center of the washer and blade.

Using your wrench or Allen key, turn the blade bolt clockwise to tighten it. Be careful not to over-tighten, as this could damage the blade or the saw.

If your Makita circular saw has a spindle lock button, press and hold it while tightening the bolt to prevent the blade from rotating. Once secure, double-check that the blade is firmly fastened and that there is no wobble.

This process ensures the blade is safely and correctly installed and ready for your next cutting task.

Step 6: Reconnect Power and Test

With the new blade securely installed, it is time to reconnect the power to your Makita circular saw and test its operation.

If you are using a corded model, plug the saw back into the electrical outlet. For cordless models, reinsert the battery. Before powering on the saw, ensure that all safety guards are properly in place and that there are no loose components.

Turn on the saw and allow it to reach full speed, listening for any unusual noises that might indicate an issue with the blade installation. If everything sounds normal, proceed to make a few test cuts on a scrap piece of wood to confirm that the blade is cutting smoothly and accurately.

This final step ensures that the blade is functioning correctly and your saw is ready for use on your next project. Always remember to prioritize safety and double-check all components before starting your work.

Step 7: Dispose of the Old Blade

Proper disposal of the old blade is important to maintain safety and environmental responsibility. Begin by placing the old blade in a sturdy, puncture-proof container to prevent any accidental injuries from the sharp teeth.

If the blade is not excessively worn out, consider taking it to a professional for sharpening and future reuse. Alternatively, check with your local recycling center to see if they accept metal blades for recycling.

Many communities have specific guidelines for disposing of sharp objects, so be sure to follow any local regulations regarding waste disposal. By properly disposing of the old blade, you ensure a safe working environment and contribute to sustainable practices.

Following these 7 simple steps on how to change a blade on a makita circular saw, you can easily change the blade on your Makita circular saw and continue working on your projects efficiently and safely.

Remember to always prioritize safety by wearing protective gear and following proper procedures when handling power tools. With regular maintenance and care, your Makita circular saw will continue to serve as a reliable tool for all your cutting needs. Happy cutting!
