If you own a Hitachi circular saw, you may find yourself needing to change the blade at some point. Whether the blade is worn out or you need a different type of blade for a specific task, knowing how to change it is essential. Luckily, changing the blade on a Hitachi circular saw is a simple process that can be completed in just a few steps.
Step 1: Safety First
Before you begin, ensure that the saw is unplugged from the power source. This will prevent any accidental starts while you are working on the blade. Additionally, wearing safety goggles and gloves is highly recommended to protect your eyes and hands from any potential hazards.
Step 2: Release the Blade Guard
To change the blade, you need to release the blade guard. Look for the lever or button that allows you to disengage the guard and push or slide it in the appropriate direction. This will open up access to the blade.
Step 3: Secure the Blade
Once the blade guard is open, you can secure the blade for removal. Some circular saws have a spindle lock button that you can press to lock the blade in place. If your saw doesn’t have a spindle lock, you can use a piece of wood to hold the blade steady. Make sure the blade is securely held in place before proceeding.
Step 4: Remove the Blade
Using a wrench provided with your Hitachi circular saw, turn the blade bolt counterclockwise to loosen it. Once the blade bolt is loose enough, you should be able to remove it by hand. Carefully take out the old blade and set it aside.
Step 5: Install the New Blade
Take your new blade and align it with the saw’s arbor, ensuring that the blade teeth face in the correct direction. Slide the blade onto the arbor and hand-tighten the blade bolt in a clockwise direction. Then, use the wrench to tighten the blade bolt securely.
Step 6: Test and Secure
Before you start using the saw again, double-check that the blade is securely fastened. Gently rotate the blade to ensure it moves smoothly without any wobbling. Once you are satisfied, close the blade guard and securely fasten it using the lever or button.
Now you are ready to use your Hitachi circular saw with a new blade! Following these steps will help you change the blade safely and efficiently, allowing you to tackle any woodworking project with ease.

Why do you need to change the blade?
Changing the blade on your Hitachi circular saw is an important maintenance task that can help improve the performance and safety of your tool. Over time, the blade can become dull or damaged, which can lead to reduced cutting efficiency and potential safety hazards. Here are a few reasons why you might need to change the blade:
1. Dullness:
With regular use, the blade of your circular saw can become dull. Dull blades can cause the saw to work harder, resulting in slower cutting speed and increased resistance. This can lead to inaccurate cuts and potentially dangerous kickbacks. Changing the blade regularly ensures that you always have a sharp cutting edge, allowing for smooth and precise cuts.
2. Damage:
Accidental encounters with nails, screws, or other hard materials can cause damage to the blade teeth. Even small chips on the teeth can affect the cutting performance and accuracy of the saw. Changing the blade when it is damaged is necessary to maintain the cutting quality and prevent further damage to the saw or the workpiece.
3. Material-specific cuts:
Blades that are designed for specific materials, such as wood, metal, or concrete, offer optimized performance for the respective applications. If you need to switch from cutting one material to another, it is essential to change the blade to ensure efficient and accurate cutting. Using the wrong blade for a particular material can result in poor cutting performance and potential damage to the blade or saw.
Remember, always follow the manufacturer’s instructions and safety guidelines when changing the blade on your Hitachi circular saw. Taking the time to regularly inspect and replace the blade will help maintain the performance and extend the lifespan of your saw.
