Do I need to worry about leveling table saw?

I just purchased a Sawstop table saw. As long as I have all the extension wings flat and true to the table saw, do I need to worry about leveling the whole table saw? My garage floor is not 100% level and if it requires, what are some ways to level the whole table saw? I'm getting a mobile base for this table as well.

I would wait until you get the mobile base
before you fret over how level things are.
personally, anything mobile, I never checked
to see if it was level or not.

I have an older PM66 and it is dead level, about as perfect as can be. But it's not on a mobile base. Probably just my OCD kicking in but I want my equipment level.

I don't think it matters much if a table saw is level. It won't change the accuracy of the cuts. You reference blade to table, not really anything to level or plumb.

With a mobile base, unless you put it in the exact same place every time you use it, it will need to be adjusted all the time.

Mine is not level - similar garage floor issue. The only downside is that my pencil always rolls off it.

In and of itself it won't matter if the saw table is not level. When it does matter is when there is an outfeed support table onto which the material that has been cut needs to support it. It should be a tad bit lower, have a rounded front edge and at least be in the same plane as the table on the saw. WHY? When you feed the material through the saw it should not be allowed to twist or you will get a kickback. The easiest and best way to prevent this is to have BOTH tables level or in the same plane.... or co-planar.

This is correct. The saw table is flat, that is what counts. There is nothing on the saw that has any reference to gravity.

My Hitachi has casters that retract. I move it often. Never bother to level it. Just as long as it is not wobbly,I'm good. ...J.D.

You want it level enough to put an out feed table or a table to the left. Perfect level isn't rule. When they built my house they actually leveled the concrete in my garage. If I take a car covered in snow it daring everywhere. Lucky I use it for cabinets and not cars...

As long as the table saw is properly aligned, a slight tilt shouldn't matter. @woodnthings makes a good point - if the tilt is enough to affect the motion of the wood through the cut, that would be bad.

I have a SawStop cabinet saw. It is on a mobile base, and I roll it onto pillow-top paving stones outside to use it. The pavers have slightly curved tops with wide seams between them, The overall layout is barely sloped for drainage towards the right side of the saw (in the direction of the rip fence from the operator's point of view). The saw does not always go in the exact same place. Different casters may or may not be on a seam between one session and another. The saw table is as flat as I could make it, and the blade and rip fence are properly aligned with the table surface and miter slots.

I used the saw today, so I moved it to its usual spot and measured the tilt, using a Wixey WR365 angle gauge. The WR365 can measure angle from Earth level to 0.1 degrees. (It also measures relative angles.) I made slight variations to the saw's reseting place to test with the casters, seams, and pavers in different positions. Each tilt measurement was taken with the saw properly settled on its base. The average tilt was to the right, between 0.5 and 1.0 degrees off from level. I found one position that had 1.4 degrees of tilt.

Conclusion:
Minor tilt angles up to 1.4 degrees don't make a difference. Using this saw and other table saws that are level to the ground seem the same to me. My saw works well.

The floor of my basement ship is not level - despite a couple hundred buck worth of self-leveling compound... but I do have my tablesaw level and most of the nearby machine level as well. This is because I have most of my machines set to be on a common horizontal plane so that I can pass long pieces of lumber over one tool/surface without hitting something. My router table is the same level height as my tablesaw so the tablesaw wing can be an outfeed table for the router table. My central workbench is also level and can serve as the in-feed table for the tablesaw and for the router wing on that end of the saw (I have two router tables). My secondary workbench acts as the outfeed for the tablesaw. Keeping these machines level and in alignment has been very important in my small shop design.



That said, my mortising machine is on a mobile base and it's definitely *not* level. It's not practical to level some tools and it gives nothing to have them aligned or leveled with your other surfaces - as long as the tool is stable and won't tip or rock during use.



If I had a big space, I wouldn't much care about the tools being level or plumb, but in a small space shop you can get double duty if things are level and on a common plane.
