A circular saw is a hand-held power saw. The saw table rides on the wood and can turn around the blade for bevel cuts. It has a spring-loaded guard that rises as you saw and snap back to cover the blade when the cut has been made.

To saw off a piece of board with a circular saw, hold it in your strong hand and rest the front of the table on the board. The saw is powered when the trigger is squeezed. Sometimes a safety button must be simultaneously pushed to start the blade.
Making sure that the blade is not touching the board, squeeze the trigger, and start the blade turning. If the blade is touching the board when the blade begins to turn, the initial torque of the blade would rip a large gouge out of the wood. This also causes a needless load on the motor.
Some people have trouble judging where to begin the cut. With the blade turning, move the saw along the edge of the board until the blade is lined up with the cut line. Bend over so that you can see the exact place where the blade contacts the line. Cutting along a line is not a guessing game; you need to be able to see what you’re doing.
A circular saw blade cuts a kerf that can be 1/8 inch wide. For accurate cuts this kerf should be on the waste side of the line or else the piece you have measured will be 1/8 inch too short. Now push the saw into the wood and move it smoothly along the waste side of the line until the waste piece of wood drops off.
