Handheld Circular Saws Circular saws are used for straight
sawing. Depending on the blade, they cut either across
(crosscut) or with (rip) the grain of the wood. The operator
adjusts the height of the blade and, while holding the stock,
pushes the blade through the work piece to perform the cut. -
Contact with the turning blade. Portable circular saws must have
an upper guard that covers the entire blade of the saw and a
retractable lower guard. [29 CFR 1926.304(d)] Hand-held
circular, reciprocating, saber, scroll, and jig saws with blades
greater than one-fourth inch must be equipped with a constant-
pressure control. [29 CFR 1926.304(f)] Additional Safety
Measures When using a hand-held saw, the blade should be
directed away from the aisle and any people who are in close
proximity to the saw. Use the proper blade for the material
being cut. Maintain sharp blades. Always wear eye and face
protection. Circular handheld saw in use Portable circular saw
