Hi LJ,

I was just using my Sawstop PCS 3HP to cut on some tenons on some cherry using a dado blade. I had made over a dozen cuts by this point with the current dado blade/brake setup when all of a sudden heard a loud bang. I jumped. Them realized the brake had fired. Honestly, cannot figure out why. I took about a dozen pictures from every angle thinking perhaps my miter gauge had touched the blade, but NO. Checked out the piece of wood for signs of metal nothing. The piece of wood was kiln dried so should have had a low moisture content plus had already made dozens of cuts using wood from the same board with no problems.

Has anyone else had this issue? Have you had any luck contacting SawStop? Will they replace the brake and blade?

+1 Contact Sawstop.

You send the brake to them at your cost if you want it checked. They hook it up to a computer and check data.
The data can show the difference between metal, wet wood, hot dog, and/or human flesh triggers. If is was nuisance trip, you get a replacement brake returned to you. If not, tough luck.

Another reason to call: Sawstop recalled a small batch of randomly failing brakes several years ago. Have your brake in hand to give them serial number details when you call.

Best Luck.

I've not heard they will replace the bade, though most folks do seem to get a replacement cartridge. Regardless, they should know about your mishap.

Update: I did call SawStop. Didn’t get any promise of a new blade or a new brake cartridge. The technician I spoke with said they only send out new cartridges in the event of a finger strike which this wasn’t. He did say I could send them the brake cartridge at my expense and they would download the data. He also mentioned that I could try and see if I could replicate what happened in bypass mode. The saw would indicate a brake activation code even though it would not actually trigger the brake. I have been trying (in bypass mode) and regular mode with a regular blade and brake but no results.

For the dado stack I was using I am wondering if it’s actually ruined. After pulling the brake off the blade, the blades and chippers seem to be in remarkably good condition. Haven’t tried cutting with it. Looking at the price of replacement components though ot looks like I may as well buy a new dado set. Price wise it would be almost the same once taxes and shipping are factored in.

Well, look...nuisance trips seem to be a minor thing at this point, you don't see too many (I realize this is all relative). Besides it might not have been the saw, ti might be the brake that was faulty or even some undiscovered thing you overlooked.More common are accidental trips, where someone runs their miter gauge into the blade or some such happenstance.

I can honestly say this was not the case for me (miter gauge touching the blade). The tech I spoke with on the phone also mentioned cases of rivingknife coming loose or static electricity buildup.

Sorry, I wasn't trying to imply that it was your particular cause.. But even wet wood will set it off (extreme cases, like treated lumber) so there will be occasional misfires that defy explanation.

Nusiance trips is the main reason I will never buy a SS. At 88, I still have all 10 fingers to gamble with.

Same here. At 71 yrs old all digits are still attached. Main reason I'll never buy a SS is because I'm perfectly happy with my old no frills 220V Uni. My truck doesn't steer itself either LOL.

I had a defective cartridge out of the box, didn't loose a blade since it did not work. Sent it back to Sawstop and was shipped a new one fairly quick. The issue with the sawstop and fingers, I have had 3 friends that sure wish they had one. Two were professionals and just made one mistake. Dan

Aside from the nuisance trip I’d give this saw a 10/10, maybe now a 9/10 with the brake trip. Fit finish, alignment and instructions are all excellent.

Another update:
Just got a response from SawStop. Here is the email they sent me:


CASE ID: 112-175066
Thank you for contacting SawStop Technical Service. We sincerely appreciate your business.
We received the brake cartridge you sent in for evaluation. After analyzing the data from the brake cartridge, we determined the brake activation was most likely due to electrical noise. We are shipping you a replacement brake cartridge free of charge with updated firmware.
