Hey, folks. You all helped me replace my BT3000's brushes last summer. This year I loaned it to a friend and it came back not getting up to speed and burning through wood. Other than making sure I'm plugged in directly to a good outlet and not using an extension cord, does anyone have any ideas for what might be wrong?
Slow/low power.

D_Meister has a point about the blade possibly being reversed.
Other things that catch/drag and thus burn are riving knife/blade guard offset not adjusted right.- offset right or left.
Why don't you ask your friend what he adjusted/removed and replaced or otherwise touched if you know it was working before. Because things usually just suddenly go south on you; there's usually a reason..Last edited by LCHIEN; 07-19-2020, 10:53 AM.Loring in Katy, TX USA
If your only tool is a hammer, you tend to treat all problems as if they were nails.

I just put on a new blade and checked the setup. All seems right.
New problem: Turning it on trips the circuit breaker. Taking it to my shop where there's a 20amp circuit to see what happens there.

The BT3x00 has reasonable power but it is on the edge where just a bit of extra drag can hold it back. If the blade you had on it had some resin build up, that heats up quick and acts like sticky glue, slowing it down considerably. A cleaned blade helps a lot.
Another idea, if he created that much sticky resin on the blade, that kind saw dust (as opposed to dried wood sawdust) can be sticky too and build up on the motor inlets and causing it to overheat quickly. Blow the motor out well while you are working on it.Hank Lee

It ran for about 45 seconds on the 20A circuit, but it sounds wrong and doesn't seem to be up to speed. Then the breaker tripped.
Electric motor issue, I assume? Drat.

Did your friend have trouble with it? Sounds almost like the motor is burned. How does it feel when you just manually rotate the blade (saw unplugged of course!), are you feeling any resistance?

Sadly, the armature is toasted. It will cost around $400 to get it fixed.
Thanks to those of you who tried to help.

Bummer. $400 to fix a saw that cost $500 new. There has to be a complete BT3000 or BT3100 motor out there for sale. Wasn’t someone parting out a saw here recently?Jim Frye

I've got to say that is a tough lesson to learn... you don't lend something like a BT3100 out to anyone. I've seen too many guys who don't know how to use tools, especially saws. The BT-series is a great saw, as everyone on this forum knows, but you just can't jam stock through it like it was a big induction-motor saw. I'm not in the trades, but over the years I've witnessed more than a few guys who think a saw should cut just as fast as you can shove the stock through it. You get a "friend" who uses a saw that way and you can almost guarantee they'll destroy a BT in short order.
That may not be what happened here, but if so, it's an expensive risk helping out someone.

Let’s start up a DO NOT EVER LOAN OUT THIS TOOL list, ( kinda like the good tool list at Harbor Freight)
The first tool I put on the never loan our list is .........
#1. Gasoline Pressure Washer
#2. Portable Table Saw
if you are ever foolish enough to loan out your gasoline pressure washer, when it comes back it never works the same. Usually the borrower has allowed it to roll around in the back of the truck or car and it has turned over several times, and the gas tank is bent or loose and the spark plug is broken off.. Then they tell you they couldn’t get it to pump much pressure, that they had trouble cranking it up and had let it run while they went to find a water hose. Duuuuuh, they have just burned the pump up.

There 4 motors on eBay, one at $49 with no bids and the others at about $120-$170 buy it now price. That plus shipping and a few hours of your time to remove and replace. Additionally you’re without your saw for a while.
good advice to not loan a table saw.Comment

If you are not in a big hurry to get it going again - about every 6 months or so, someone parts a saw out either here or on eBay. Sometimes you can get a replacement motor for a decent price.Hank Lee

I've found the Craftsman version of the saw on Craigslist for $200 that I'm considering, and I'm looking at motors online, too. Did the motor change year-to-year? Or will I be okay with any BT3000 motor?
I can get by without it for a bit (although I'll need to borrow a jobsite saw on Friday to help my dad-in-law). But you're all correct: I'm not loaning the table saw out again.
