When you notice these signs on your miter saw blade, that’s a green light telling you that the blade needs to be replaced. So, hang on as you learn the step by step procedures on how to change a miter saw blade to achieve overall maximum productivity.

What is a Miter Saw?

A miter saw is a tool used to make rapid and precise cuts on a piece of wood. The saw is more suited for making crosscuts and miters. What actually makes these cuts is the miter saw blade. Without a blade, no cuts can be made.

Why Should a Miter Saw Blade be Changed?

There are different factors that can affect your decision to change your miter saw blade including the following:

  • You need a different blade for another job; miter saws are versatile tools meaning you can use them for many tasks. Each task, however, will require a different blade from the one used for the previous task. For instance, you will need a different blade to cut wood and another blade to cut metal using the same miter saw.
  • Blunt blade: a blunt blade is one of the most common reasons people change miter saw blades. Continuous usage of a particular blade will render it blunt after a while and thus, require the user to get a new blade installed to carry on the task.
  • For maintenance: as with all tools, the miter saw also requires a level of constant maintenance, or else, it becomes a piece of junk incapable of making cuts. You might need to remove the blade occasionally to effectively clean and oil the moving parts and the blade itself.

Lock The Blade

You need to lock the blade to prevent movement. Press the spindle lock and it should do the trick. The spindle lock should be a button located at the front, but if you aren’t sure where it is or what it looks like, then check your manual.

Remove The Blade

Remove the blade. To do this, use a wrench to turn the bolt holding the saw in place in a clockwise direction. When the bolt is loosened, take off the outer washer and you are ready to install a new blade. The outer washer is a flat ring-like metal.

Before you install the new blade, you need to oil the washers (the inner and outer washer). Clean the washers gently and add a few drops of oil. This will increase lubrication and improve the overall efficiency of your saw.

Install The New Blade

Install the new blade. Put in the blade and the washer. Make sure to screw them correctly and perfectly to prevent any mishaps while working.

Test Your Saw

Place back the blade guard and screw in the bolts nicely. Ensure every part of the miter saw and the new blade is fitted perfectly.

Clean up the saw, unlock the spindle lock, and have a test run to ensure it works well. If you hear any unusual sounds or chipping, turn off the saw. It probably means you missed a step or a part is not properly fixed in. so, check the tool again.
