I picked up a used TS3612 and looking to get acquainted with the saw (I did download the manual too). Took the blade off (Typical use of wood block to loosen) but when putting back on I'm a bit concerned. The manual shows using a block on the other side of the blade; but my concern is that this does "tighten" the nut but does not let me get "very tight". The center bolt (blade arbor I guess I can call it) spins once just past finger tight. There is not a nut on that side - it is just the round shaft. The manual does not show a nut on that side and just using the wrench and a wood block - but this seems less than ideal tightness to me. Move times I see any video of other saws people have a pair of wrenches and get the blade pretty tight. Is this an issue with my TS3612 (could use a vise grip or similar on the alternate side i suppose - just wondering what is really correct in terms of tightness on this saw.

Welcome to SawdustZone! Snug is tight enough generally for table saw arbors. Due to centrifugal force the fastener is self tightening to some degree. -

It's a reasonable question.
Yeah, the block of wood jammed under a tooth is a non destructive way of keeping the blade from turning and allowing you to tighten the arbor nut.
If the wood is on the side of the blade, that is to push the blade against the arbor so you can tighten the nut to finger tight, apparently.
The arbor is inherently self tightening (that's why its a left handed nut!!!) and does not take a massive amount of force to tighten sufficiently. I recommend finger tight and then maybe a 1/8-1/4 turn tighter until its pretty snug. Don't need to crank down on it.
Overtightening is bad because it can warp the blade and distort it making the cut worse.Last edited by LCHIEN; 08-20-2025, 12:36 AM.

If your only tool is a hammer, you tend to treat all problems as if they were nails.

Not to be obnoxious about being safe by lecturing about unplug the saw, safety glasses, gloves, ear muffs and all that kind of stuff, there are plenty of things to be cautious about. The flimsy thin stamped metal arbor wrenches have probably been more responsible for knocking off large chunks of finger and knuckle hide as a spinning blade has. These cheap wrenches are clumsy and awkward and will slip off the nuts causing you to drag your fingers across the blade and against the table. It gives you a good badge of honor and scars you can show to your grandkids!
