I bought a used Uni last Saturday from a guy who said the saw had not been used in about 4 years. like yours, weight of the motor had been on the belts. Mine would rumble for a few seconds after start up, and I was concerned about that. Rumble got much milder after running for a while. I took the blade off and started the saw while observing the belts, and they do not appear to be running/turning smoothly at all….they’re “jumpy”. As mentioned above, I’m pretty sure they’ve taken a set from sitting so long with the motor weight on them, and bet you’re in the same boat. I let mine run for a few minutes a couple of different times. Now the “rumble” is way less so I think the belts have re-shaped some. Regardless I plan to replace the belts with a matched set from Delta.

I get a minor noise/low boom sound on start up, and attribute that to the INSTANT power/rpm’s on start up. Hit the go button and it just lights up immediately. Would be nice if it had a “soft start” feature.
