Is your saw not cutting like it used to? Don’t get rid of it! Saw blades wear out, and changing a blade on a table saw, circular saw, or mitre saw is very simple. In fact, the manufacturer intends it.
We recently employed these steps to install the Final Cut Sanding Saw Blade on an old mitre saw. The result: the saw performs just like it came off the manufacturing line.
Remember, always follow the manufacturers’ instructions for changing your saw’s blade. You may want to wear leather gloves since saw blades are, well… sharp.
Step 1: Unplug the saw. Remove the guard housing from the saw. Most saw designs make this a pretty easy task. On our mitre saw, three screws held the guard in place.
Step 2: Locate the blade lock if one exists. This will allow you to use channellocks or a wrench to remove the bolt that holds the blade in place and prevent the blade from spinning. If the saw doesn’t have a blade lock, you may have to use a piece of wood to stop the blade (see the picture below).
Note: Saw blades are held on by a reverse-thread screw and nut. This keeps the nut tight when the blade turns. Turn clockwise to loosen.
Step 3: Remove and replace the blade, and hand-tighten the nut. Make sure to replace any washers, especially a pressure-style washer against the blade.
Step 4: Use channellocks to tighten the nut. Turn counter-clockwise to tighten. Again, you may need to use a block of wood if there’s no blade lock.
Step 5: Replace the guard and ensure the guard operates correctly as you lower the saw arm.
That’s it! Really simple right? We thought so.
