I only have two minor concerns with this saw but they are so small that this saw still gets a 5 star rating.  DEWALT could step up the game on the dust collection if they offer users an effective way of using the dust port on the blade guard. Maybe they offer an accessory splitter and hose package. My other concern is the plastic parts on the fence where it connects to the table. I suspect those parts could break when they are cold if you remove the fence and toss it in the trailer or back of your truck. Again, these are minor in comparison to the rest of the saw (food for thought on the next design).
I have read dozens of reviews for Dewalt,Bosch,Baileigh,Grizzly and others and from my perspective (regarding Dewalt at least), Black&dDecker/Stanley have turned the product line , for the most part into junk. I have read reviews that indicate outright, that the table is not level, the fence is warped and if you want accurate cuts, then possibly you should look elsewhere.

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.

Regular table saws usually have powerful motors that can give you of 3 to 5 HP at 240V. Powerful benchtop saws such as these can take larger materials like wooden flooring, logs, and lumber. On the other hand, smaller and more compact table saws have direct-drive motors that run on 120 V power at 2 HP. This kind of saw will work with thinner materials like wooden panels, vinyl, laminates and thin metal sheets.

The power switch is a bit finicky.  I noticed this at their media event and also when using the saw.  A quick press of the on button does not work and it seems that you have to press the button for a few seconds.  Additionally, you need to push this button straight on and not at an angle to work.  My guess is That Dewalt will work this out in time.

The shark fin-style riving knife behind the blade keeps cut pieces from binding and causing kickback. The included push stick is useful when using thinner workpieces that don’t allow your hand to be at least 4 inches from the blade. The power button’s flip cover ensures that you only turn the blade on when you mean to, which is a welcome layer of safety.

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.

How and where do you intend to use your table saw? If you plan to take it from one worksite to another then you must use a job site table saw A job site saw is portable, compact and usually has its own stand and may or may not have wheels. Stationary table saws are also called bench top saws because these don’t come with a stand. These rely on a table or a workbench to support the weight of the saw. There are also cabinet table saws which are heavy duty saws that are mounted in a metal or cast-iron cabinet. These saws are very heavy but are usually made with moving wheels and complete cutting features.


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.
