How to Change the Blade on a Ryobi Circular Saw

Ryobi manufactures many types of power tools, outdoor products and painting supplies. Ryobi's line of circular saws are designed to make precision cuts in a variety of surfaces, including wood and PVC. The saw's blade contains several teeth that spin rapidly to glide through the material being cut. After regular usage, the material begins to dull the blade, making it more difficult to make cuts. When signs of dulling, such as difficulty making cuts, louder cuts and burn marks on the side of the wood, are identified, change the blade on your circular saw.

Step 1

Unplug the saw's power cord from the wall outlet or extension cord.

Step 2

Press and hold the spindle lock button to prevent the blade from moving. The spindle lock button is located above the blade on the top of the middle of the saw.

Step 3

Loosen and remove the bolt in the center of the blade using the blade saw while holding the spindle lock button.

Step 4

Remove the spring washer and outer blade washer from the blade spindle.

Step 5

Lift the blade guard and then remove the blade.

Step 6

Wipe a drop of oil, included with the saw, onto the inner flange bushing, which is the piece that contacts the center of the inside of the blade.

Step 7

Wipe a drop of oil on the outer blade washer, which is the washer contacting the center of the outside of the blade.

Step 8

Lift the lower blade guard, then place the blade onto the spindle.

Step 9

Hold the spindle lock button once again, and replace the spring washer and outer blade washer.

Step 10

Install the blade screw into the spindle, then tighten using the blade wrench.
