I’ve already communicated with SS about this and was basically told it was normal, there are 4 gears involved, etc.

But there is backlash. I’ve confirmed this in numerous ways, both by feel and with a digital height gauge. There is a 20-30° arc of turning where the blade does not move. Here's a video if you want to see it.

It’s not a monumental deal, but when adjusting the blade height it you change direction it is a bit aggravating. I’ve had two other Jet table saws that did not do this.

SS told me to call them back if I am not satisfied, which I may do. If anyone has any experience with this or knows of an adjustment to tighten up the gears, I would like to try that.

I see that as normal. Not to make you feel bad, but my ICS has about 1/8 that amount of movement before the blade moves. Even so, I’m not sure I would be upset about the amount you have. My Unisaw had at least that much.

I saw this earlier today and just checked mine out in the shop. I, too, have some lash in the elevation wheel; it’s perhaps close to the amount your video shows. I’ve noticed it before, but it seems on a par with the contractor saw I had before the SS, and is similar to the lash I experienced on the PM66 I used in the military base hobby shop.

My saw is due for a cleaning and when I do that, I’ll follow the owner’s manual instructions about reducing lash. Interestingly, the manual doesn’t call it “lash”. It refers to it as “play” and indicates that it should be adjusted if the play exceeds 1/8th of a turn of the wheel. That’s the same for both elevation and tilt.

Getting my saw moved so that I can access the panels for the cleaning and adjustments will be one of those winter tasks.

So what? My saw has 1/3 of a turn. Its neither a critical nor specified spec. I use a DRO for setting and have no trouble hitting to 0.001”. It’s easy (at least on my saw) to flip back and feel the backlash tighten up before it moves so I don’t normally overshoot.

What is the problem. You have to have a certain amount of lash in a gear train or the gears gall and weld together. The more gears the more lash.
You are sounding like someone with buyers remorse.

That looks like a very reasonable amount of play/lash. I had an almost new milling machine that had more play than that in the table movement wheels.

Thanks everyone, I can live with it, my only reference was my old saw. Just needed some perspective.
