How To Change Mitre Saw Blades

Materials Needed

Before starting the process, make sure you have the following materials:

  • A new mitre saw blade that matches the specifications of your saw
  • A wrench that fits the bolt on your saw’s arbor
  • Safety goggles
  • Thick gloves

Step 1: Unplug the Saw

The first and most crucial step when changing a mitre saw blade is to unplug the saw from the power source. This is important to avoid any accidents or injuries when working on the blade.

Step 2: Raise the Blade Guard

To access the blade, you need to raise the blade guard by pulling it up and back towards the handle of the saw. Make sure the guard stays in this position throughout the blade changing process.

Step 3: Loosen the Blade Bolt

Use the wrench to loosen the bolt that holds the blade in place. Turn the wrench counter-clockwise to loosen the bolt, and be careful not to damage the teeth of the blade while doing so.

Step 4: Remove the Blade

Once the bolt is loose enough, remove it completely and take out the old blade. Be sure to handle the blade with thick gloves to avoid any cuts or injuries.

Step 5: Install the New Blade

Place the new blade on the arbor, making sure that the blade teeth are facing downwards. Tighten the bolt by turning the wrench clockwise until it is snug, but be careful not to over-tighten it as this may damage the blade or the arbor.

Step 6: Lower the Blade Guard

Once the blade is securely in place, carefully lower the blade guard back into position. Make sure it sits flush against the saw and that it moves freely up and down.

Step 7: Test the Blade

Before using the saw, it is important to test the blade to make sure it is properly installed and secured. Plug the saw back in and turn it on. Gradually increase the speed of the blade and listen for any unusual noises or vibrations. If everything sounds and feels normal, you are ready to use your newly installed blade.
