I've had a SawStop Pro 1.75hp 220v saw for approx. 5 years now. From day one it tripped frequently - both the breaker as well as the thermal in the saw, especially when cutting hardwood. Even with a fresh Freud Glue-Line blade it has a super-tough time cutting 4/4 kiln-dried maple/birch, even walnut and poplar seem to be a chore with it tripping frequently. 8/4 anything...forget about it. We regularly have our blades sharpened, we use the appropriate blade for the corresponding materials/applications and don't cross blades from materials like MDF and melamine to plywood and solid wood. If blades appear contaminated we give them a quick wipe down to lower friction and buildup. We're pretty fastidious with our methodology and tools.
With that said, I've spoken with SawStop reps and they insist that it's either operator error (wrong blades with the wrong materials) the speed at which we're feeding the material (I've been doing this for 20+ years) or most likely, the way it's wired in our shop. They've indicated that they personally have these saws in their home shops and that they experience little trouble if any in the circumstances suggested. I've had multiple electricians look at our setup, read the literature, specifications etc and all insist that the way it's wired is above and beyond adequate. I've gone through more blades at $100+ each thinking maybe the sharpeners missed the boat and did a shoddy job, though they've worked perfectly on our other saw(s).
The saw and it's behaviour seems to cycle: some days if we're ripping hardwood it'll trip the breaker upwards of 20 times (yes, the breakers been replaced 4 times now to ensure that it isn't faulty) other times it'll kick the thermal as many times...and when I say 20 times I'm not talking during the duration of an 8 hour work day, I'm talking over the length of one 8-10' board that's already been trued on the jointer and planed. The saw doesn't have any reason to labour to the point where it's kicking - and with that said I had a 40+ year old Delta with a belt-driven 1.5hp motor that operates more reliably, as will my DeWalt job-site saw.
Both shops I had/have the saw in are climate controlled and dry. Dry material is only ever cut. The saw is cleaned frequently with compressed air and brushes. It's also hooked up to full dust collection from the cabinet base as well as the large SawStop over-arm collection system. I can't see anything situational based on settings that could be contributing to this issue.
Am I missing something here that SawStop isn't telling me, or even an electrician? SawStop had us replace the contractor box...didn't help a bit. Now they're MIA and likely sick of hearing from me as this has been an issue we've struggled against pretty much from day one. Any feedback from individuals with this saw - similar or contrary would be great peace of mind. I'd love to know - even if it's just me having this issue!
Any advice would be greatly appreciated, especially before I face what seems to be the inevitable and go down the route of investing in another costly saw.
Thanks in advance!
