Strange chop saw problem

I'd start with my multimeter and the Switch

Yep, the switch went out on mine, but it stuck in the on position.

If this has plastic brush holders the problem could be that the holders got hot.The deformed plastic is likely stopping the brushes from contacting the comutator. If it is the problem give the carbon brush a stroke with a file on all four sides of the brush. This usually fixes a very common problem.

You got you're nickles worth... Time to spend some more....

Id move the plug around while holding the switch down. Push the wire into the plug. Also imspect the wire for damage. Simple things but might save you a lot of useless trouble shooting.

OK, I will mess with switches, brushes etc, using a multimeter, I also suspect brushes, this behavior is quite atypical.

======================== If its not the switch, try rotating the blade a few degrees and then hit the start switch. [several times] If it comes to life in another position you have armature/comutator problems. Be sure your fingers are clear of the blade before hitting the trigger. If you are very careful, try spinning the blade and hitting the trigger.

Did not work... I will open up the handle with the switch, and see if

What has your multimeter said so far?

I got one of those cheap chop saws from an asshole on eBay and it fried a brush within 2 minutes. I still haven't found a replacement, but I'm only out $10. (eBay forced a partial refund after the guy never returned my calls/emails.)

It sounds like either a brush died, a lead came off, or the switch went out. There's not much else in the system but for the motor windings, and they're usually machine made and fairly reliable from what I've seen.

it said that switch functions just fine.

Well, I know that switch is ok. I am sligtely drunk right now, and will resume repairs tomorrow.

I fixed it. it was easy. the little brush caps became loose and so did the brushes. I s\imply had to tighten them slightly.

I might forget also, since I was slightly buzzed from beer. If I ask again, do not call me stupid.

======== Thanks for the feedback and "the rest of the story."

Glad it was simple and no-cost. Now if I can just remember this when I have the same problem.....

Usual problem is one or both brushes stuck in their holders. Check that they are both free and actually contacting the commutator.

Yes. I retightened those holders and everything was fine. Since I opened the handle to look at the switch, I noted just how thin the wires are inside the handle -- at best they are 16 gauge wires.

Why drink? You never actually BUY a 6 pack, you only rent it and if its the buzz you want, have the old lady wrap a nylon stocking around your neck for no more than 3 minutes.

I drank because I wanted to go to bed early.

========================== Please advise name/brand of beer ASAP.

I have tried that approach many times, generally with no success. I had no idea this was because I was drinking the wrong brand......
