A few weeks ago I got a new Delta 36-725. It wouldn’t start when using my 50’ extension cord. After switching out the cord for a shorter/heavier one, the saw started and I thought my problem was fixed. A few days pass and this weekend I built a crosscut sled, but ran into the same problem. On startup it would just buzz, move an inch and never start. I tried multiple outlets and finally got it to start after using an outdoor outlet.

I went ahead and made a few cuts on 3/4” pine plywood, but it was slowing and requiring some effort to push the workpiece through towards the end of the cut. I’ve used a cheap portable contractor saw before, and this wasn’t cutting nearly as easy as that did.

I’ve read that the factory blades that comes with saws are usually pretty bad, so I attributed it to that and bought a Diablo 50T Thin Kerf combo blade from Woodcraft. It didn’t help. :(

After making a few more cuts, I went to turn on the saw and it wouldn’t start at all. I looked on my wall panel and it had just tripped the 20amp breaker.

Tonight I tried plugging it into my Washing Machine outlet to see if it’d work on a dedicated breaker. Then this happened: https://www.dropbox.com/s/f7sny6bw1f4rykq/VID_20160801_224940.mp4?dl=0

The first click at the end is the saw tripping it’s own internal breaker. This is the first time that’s happened.

At this point I assume it’s either a problem with my wiring or the saw. I’ve never had issues running anything else off these outlets before, so I’m starting to think it might be the saw.

Any ideas? I’m new to this, so there may have been something else I’ve overlooked.

Call Lowes about returning it, but I got a feeling they will say to contact Delta for the warranty. I hope you did register it with Delta for the warranty?

Your saw has a blade brake. Could it be the problem?

Could have a bad capacitor….possibly caused by excess current flow due to the 50’ extension cord. Should be under warranty….if that’s the culprit, it’s an easy fix even if not covered under warranty.

It does have a blade brake. Dagobah, just for curiosity with saw unplugged turn the blade by hand to see if there is a lot of resistance.

Yeah.. that was a bad move to run that saw on a 50’ cord. It could have damaged the motor.

I can spin the blade when unplugged. It doesn’t spin freely, but has some resistance.

Keep in mind the saw never actually ran on the long cord. I plugged it in, wouldn’t start and got another shorter cord. I’d hate to think that damaged the motor. I had no idea.

Just got off the phone with Delta and Lowes. Delta said it sounds like a bad starter capacitor or possibly the motor. They didn’t think the long cord could have done it. Lowes was great, and said they’ll sell me a new one, deliver it for free and pickup the old and do a return at the same time.

I didn’t have an easy way of returning the saw, so this helps a ton.

That sounds like a good solution! It is to be hoped the next saw will be MUCH better.

The use of an improperly sized extension cord will cause the motor to overheat, eventually causing the motor to fail due to the breakdown of insulation. However, it would require a bit of use under that condition to get to that point, so if you just plugged it into one and it didn’t run, I doubt that caused any damage.

It wasn’t said how long the saw was used on the 50’ cord before it would no longer start. Depending on the voltage drop it could damage the motor in short order.

Go back and read response #8 above. But it’s irrelevant at this point, since it’s being replaced under warranty.
