Steps for changing a circular saw blade Unplug the saw’s power cord from the electrical outlet or extension cord. Use the blade wrench to tighten the arbor nut until it’s snug; be careful not to over-tighten the nut or it’ll be difficult to loosen it the next time you change the blade. If the saw has a diamond-shaped arbor, straddle the blade over two wood blocks and use a hammer or punch to tap out the diamond insert from the center of the saw blade.
