Follow instructional manual

The saw’s instructional manual is the idealist best place to get information when it comes to replacing saw blades. Some saws come with blade release switches for an easier removal while others need you first to loosen the bolts holding the blade in place.

Removing the blade

There are cutting machines that come with a rotation lock to give room for fastening the shaft that holds the blade in place. You can use the wrench to unscrew the screws. Once the bolts are loose, finish unscrewing using your fingers. However, if your saw comes with a hex bolt, then you will need a wrench to do that.

If your saw does not come with a rotation lock, stick a bar through the center of your blade so that you can hold it in place as you unscrew the bolt. You can also choose to wedge the blade into a wood scrap. Unscrew the bolt in the opposite direction to the rotation of the wheel.

Place the machine safely on the ground

Once you remove the blade, place the machine as well as the blade in a secure place and pull back the blade guard. If your saw comes with an arbor lock button at the top of its housing, press it in. The arbor lock is the shaft that you install the blade on.

You can effectively do this by laying your blade flat on two pieces of wood, leaving the b enter of the center of the blade hanging on the gap between the two planks of wood. After that, punch the arbor with a hammer.
