Smaller, portable table saw models have direct-drive motors that can operate on 120 V power to produce 2 HP. This is enough motor power to take on thinner materials. Table saws with more powerful motors are usually stationary saws that produce between 3 to 5 HP. Table saws with stronger motors rely on a belt drive to transfer the power from the motor to the blade and these operate on 240 V.
Further testing showed that the red “Stop” lever was the cause, not the power switch. After turning on the saw, the red stop lever would drop too hard onto the stop button and turn the saw off. After conferring with the product manager at Dewalt, it was determined that the red stop lever spring force was too high. The units we tested was from a “manufacturing sample lot.” MSL’s are the first time the plant does a big run of the product and Dewalt then has time to refine and make adjustments, before the tool goes to production.
