Lift the blade housing upward by gripping the left end of the housing. Tilt it on its axis to the right side. The housing will stay in the upward position until you manually push it down.
Locate the round dial used to open and close the chuck jaws on the base of the machine and rotate the dial counterclockwise until the jaws rest far enough apart to place your stock or cutting material in place.
Place the material between the jaws and then slide the roller support under the material to support the end of the material not in the saw. A roller support is a long roller bearing on a pedestal that you can raise or lower. Make sure the roller butts up against the bottom of the cutting material.
Close the jaws onto the material to lock it in place. It is important that you close the jaws tight to keep the material from moving.
Locate the knob that controls the rate of speed for the self-lowering mechanism that controls how fast or slow the blade housing lowers. For harder materials such as metal, turn the dial clockwise to lower the speed. For softer materials such as wood, turn the dial counterclockwise to increase the rate of speed.
Turn on the saw and then tilt the blade housing down until the self-lowering mechanism stops the blade. It will allow the blade to lower the rest of the way at the predetermined speed. The machine automatically turns off when the blade completes the cut.
