The Dewalt Cordless 8-1/4” Table Saw power switch is located on the front, lower left area of the saw and has a large red stop switch that can also be accessed easily with your knee. The power switch is electronic and the saw operator now has to push a green “on” button as opposed to pulling on the “red” power lever as was the case with older models.  The power switch also has a flip over safety cover that can be secured with a pad lock. The padlock hole diameter requires a ¼” maximum diameter padlock

DEWALT’s recent release of three new job site table saws is capped off with the all new DWE7491RS. This 10″ job site table saw with roller stand is their premium offering. We recently also reviewed the DWE7480 and DWE7490X which were released with this saw. The DWE7491RS is very similar to the DWE7490X except that it has a larger rip capacity and a much nicer stand.

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.

Blades come in various types and sizes. There are rip blades for cutting along the wood grains, hollow ground blades ideal for various materials, crosscut blades suitable for smooth and precise cuts, and combination blades for that double up as blades for crosscutting and ripping. Depending on what you do the most, it’s necessary to choose the right blade type and size that will get the job done with the most ease.

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.
