Finally got a table saw. It came UPS with liftgate, and I was glad the driver had a pallet jack so we could just push the thing in my garage. I think the shipping compaines will tell you they can only drop curbside because they don't know what they're getting into until they get to your house. The main unit is under a simple cardboard box strapped to a skid.
The third image is what you have to move; I had to put mine in a basemenet going down some not-so-impressive looking set of stairs.
I have a friend who is a professional material handler; he and his son used a hand truck and a movers dolley for the move. First they took it off the skid and put it on the hand truck. They said the hardest part was the two steps up from the garage into the house. I was worried about the steps holding the weight, but we did a test with several people on them and it was clear that 600 pounds was not a problem; I figured the main unit was about 375 as we moved it. One smart move they pulled was to put a dolley at the bottom of the steps and then just "land" the unit on that dolley from the last step. We just wheeled it to the spot I wanted it.
After a bit of cleaning and inspection, I started putting it together. I managed the extension tables by myself, I have an adjustable height third hand table that got me close. Then I just put in one screw on one side and then tilted the extension table up and did the other. I got the bolts fairly tight and then bumped the tables even with a rubber mallet. Came out as close to perfect as I am ever going to get it. The manual shows a trick using masking tape if there is tilt in the extension table, but luckily for me I didn't have to do that.
The front rail was a bit of a pain. The manual says to make sure it's 3/16 below the bevel, I just couldn't get it higher than 4/16, and I just set it to that. In the end, I think it's fine - I got the fence on and sliding well, although I did have to ajust it square to the table. The third extension table (black) was also no problem, just get the bolts snug and then align and parallel before tightening. I had already sprung for a Pinnacle straightedge and now I'm glad I did; it's heavy and stable and will stay in place even when you're bumping the table you want to align.
I took my time with assembly and didn't keep track of time, but I think it took about 3 hours over a couple of days. The manual says it doesn't have a plug but mine did, a nice molded piece. It's NEMA-6 conforming to the current requirements; I have a dedicate 220 V 20A circuit right next to the saw.
I did some test cuts, but as this is my first experience with table saws ever I don't know what to expect. The cross cut through pine was like butter. I then ripped a 2×4 and did feel some resistance but by all means it got the job done. Grizzly claims 3 hp but at 12.9 Amps, well, they might be exaggerating? I've heard as a general rule that 3 hp is 15 A, but in any case I think this will be plenty of saw for what I do.
I waited years to get this saw, fretting over the stairs, and then safety. I can saw now if you are thinking about getting one, just do it and you will have no regrets.
