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.

???? My initial response was post #6 in response to post #4. So post #8 hadn’t been made at the time of my comment about running the saw on a 50’ cord was a bad move.

UPDATE:

Just got the replacement saw. This one starts immediately and sounds MUCH quieter when running. The original definitely had a starter/motor issue.

I just put together my saw over the weekend and experienced the same issue. I only turned it on to make one cut to make sure it worked but it kept blowing the fuse when I would turn it on. I tried another Chord and it worked. Should i be concerned or Try something else? Maybe different size Chord?

Take a read on my #9 comment. Delta said this was likely a bad motor. Lowes replaced, no questions asked. They even delivered a new one to my door and picked up the old saw for no charge. New model worked fine.

Ok interesting. Well I just ordered a new power chord that meet the Specs. If it continues I will contact Lowes also. Did you have to sign up for a Warranty with DELTA or just use your Lowes Receipt as your proof of purchase?

Would like to revisit this topic if anyone can help…. Purchased this saw yesterday, spent all morning putting it together and fine tuning it. Made 7-10 cuts, no issue. Unplugged saw and plugged in dewalt dw735 planer. Used planer for a little while plugged saw back in and in slowly spun for about 5 seconds before tripping 20 amp breaker. Had to leave house for a couple hours, came back pushed the reset button on the motor plugged it back in directly in outlet (no extension cord) and it starts slowly and as it works it’s way up to full speed, breaker trips again. Any ideas?

Delta is not what it was. Hope it will be covered as above, sounds like a motor issue. Good luck.

Just about all motors on newer equipment include thermal overload protection. Motors run with inadequate power will not burn up. However, they will trip the thermal overload breaker.


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

Thanks ArtMann. Took it back to Lowe’s and got a replacement. Fingers crossed on this one…. If it fails , will be researching and asking advice on a different one.

Slow starting and tripping breaker is a sign of a bad start capacitor.

FWIW – If a tool was working, then stops working, such that when a motor starts to turn, usually too slow, then trips the overload or breaker; majority of time the problem is start capacitor. The other occasional problem is the centrifugal switch in back of motor is junked up with saw dust, or needs adjustment.
If its a new saw, 1st start up, remove change the extension cord first, then look inside for bad parts.

I know we are talking about a new saw, but I would pull the fan cover to inspect the switch, and check out the start cap. Capacitor is $15-20 part at local motor store, and $8-12 online. Would call Delta and request a new start capacitor, if find switch is working.

Maybe it’s just me, but hauling a fully assembled saw back for new one that needs assembled also, is worth $10-15 in parts and my time to figure out what’s broken?
If the motor is really bad, with shorted winding’s, showing interference inside when shaft is turned by hand, or noisy/bad bearings; then yes – get a new motor/saw.

Why?
Capacitors are like bearings and considered ‘wear’ item’s in world of motors. They are not lifetime item and need to replaced every 10-15 years, or sooner, especially with heavy use or bad power line conditions.

This probably doesn’t help confidence factor:
There have numerous reliability issues with Chinese made electrolytic capacitors in last 10 years. Several PC motherboard mfg had to recall and replace millions of PC boards due short capacitor lifetimes. I only buy better Japanese/USA made capacitors for motors due historic issues, Plus my local motor shop(s) won’t carry/sell cheap $5 Chinese made capacitors anymore.

YMMV

Thanks for the feed back Why me and Captain. I totally agree with you Captain on the 10-20 dollars out weighing return and having to assemble another saw. If I had any kind of mechanical electrical skill I would definitely give it a try. Lol

Check with manufacturer before taking motor apart, it may void the warranty.
