So my new saw (Ridgid 4512) has been running fine, took a while to heel the blade, etc, but I finally have cuts I’m happy with. I’ve put a new blade on (CMT 40T general purpose) and I’ve done maybe 20 linear feet of cutting in it? Maybe?

Anyhow today I put in a new Leecraft ZCI, cut it, and then started doing some test cuts in scrap 3/4” ply with my new Incra mitre gauge. All of a sudden the saw can’t cut 3/4” ply. The blade slows and has come to a complete stop after as little as 6” of cutting.

The blade seems sharp still, it hasn’t cut anything harder than 3/4 red oak, but out of the blue the saw is next to useless!

Any ideas what to check?

Lol with BentlyJ. Even if you did, King, deny it and come up with a trunnion issue, or something more sexy;)

lol, one of the first things I checked. It’s on right.

The thing is it’s not burning, the motor literally stalls out and the blade stops.

I’m assuming that you are not getting binding between the blade and the fence. That would mean that something is now out of alignment. Cause table top shifted, Trunion moved, fence moved.

I hope not, the trunions were a pain in the arse to adjust on this. I know the fence is not the issue, because it was binding when I was crosscutting with the mitre gauge only. The cuts are all square too, which is why I am suspicious of alignment being the issue.

I’ll check again I guess.

One other thing I noticed. There is a bit of squeaking when I start the saw, just for a split second. Belt tension a possible issue?

Change blades, are they ok them I’d look at the supicious blade for a problem, Bent, not seated correctly, Piece of wood between the blade and the arbor causing wobble.

If it stops the blade and the motor still turns the you have a tension issue. Is the arbor hard to turn, bearings.

Since it’s new might be a trip to HD for another saw.

Yeah not the belt, the motor is not turning. Arbor is effortless to turn.

I hope I don’t have to take it back to HD. It took long enough to build.

I have the Craftsman brother to the Ridgid 4512. I went through just about every step you describe and my saw stalled out too. Now go pull the back cover off, loosen the bolt holding the motor bracket, pull down on the motor then retighten the motor bracket bolt. Squeaking and stalling should now be gone. The belt tends to stretch out a little with use. You just need to tighten it up.

Check the nut maybe it’s not tight and the blade stops and the arbor keeps turning. OPPS, you stated that the motor stops. Any cut off pieces under that table that is jamming into the works.

Sounds like you are trying to feed stock into a 1.5HP saw too fast…

Do you have a splitter or riving knife? You may be pinching the blade? If you have neither…try putting some wood wedges to take the pressure off the blade – Other possibilities may be the motor is being starved for power – a bad controller? Blade wobble….if the arbor gets bent or out of alignment (run out) (could be a bearing going too – will surely be if that squeak turns into a whine) . Belt tension as mentioned and the other items mentioned above.

LOL to the backwords install…been there done that….was in a hurry and changed out a blade incorrectly…burned a nice piece of walnut too…..had to run it through the planner several times (need to get another jointer). I felt like a complete idiot for that….and have not done it since.

I think our last posts got over lapped or something. So, the motor is not turning? Does it make any sound? Sound like buzzing or humming of a stalled motor? It’s possible the motor is defective. If the motor is spinning and the blade not moving it could be one of the setscrews holding the pulley on the motor or arbor. That might make a squeaking noise like a loose belt.

Do you notice any smell from the motor?

A bad capacitor or bad winding in a motor would probably have a burnt rubber smell. Wouldn’t explain the noise though.

One final check is to put an amp probe on the power lead and see if the motor is pulling over amps when it’s stalling. You may need an electrician if you don’t have one of those and know how to use it. If it’s stalling and not pulling over amps, it is likely the problem is mechanical, something slipping; belt, pulley or blade.
