electrical smell from new skil 77
Bought a new (magnesium) Skil 77 and it had a wobble as it wound out. Exchanged it, and the new one has no wobble but it gives off an electrical odor remeniscent of a short, particularly first thing in the morning. Can anyone call this normal, or am I headed for trouble if I keep this saw? I like it otherwise. Thanks.

Could me the thin coating of oil burning off the new tool? I'd give it a few days and then if it persists, take it back.

I'd agree with AAA. I bought a new Hitachi chopper about 2 months ago and had the same sort of smell. It went away after a week.

Yeah, I'll third that. Give it a little while, see if the odor goes away. If it doesn't seem to go away after a few uses, try loading it down by doing some heavy cutting through scrap. If the odor gets stronger in that situation you probably have a problem.

happy?
I think the saw is defective, and some of the electrons are leaking out.
Be sure you wear a tin foil hat while using it.

But....but....but.... it's a magnesium saw, not aluminum.
Doesn't matter - The electrons are the same in all saws.
Did you hear about the Trojan and Pillsbury merger? They want to create a self-rising condom.

Yeah, but on worm drives they spin left, and on sidewinders they spin right.
It's all there in my quantum physics manual.

Of course that's only in the northern hemisphere. It's all there in my Coriolis Effect manual.
Unless they're female electrons...
That's where the uncertainty principle comes in.
Right there in the manual.

You heard about the physicist who won the Heisenberg trophy? He set it down, it became stationary, and nobody could ever find it again. ;-)

Guess he shoulda tied a superstring to it, huh?
LOL

Sounds like the flux capacitor is malfunctioning! LOL!

Of course. Can't argue with that.

the brushes may not be seated ...is there excessive sparking? does the sparking get worse when you cut?
you should only see a small amount of sparking just under the brush....not fingers of sparks or tracking away from the brushis the commutator shiny or gummy looking?
it should be dark and polished looking
Yeah there's some tracking. How do I adjust this? I'll check it out tomorrow but your response is appreciated.
As with all electronics, tools, AV equipment and computers....
DON'T BREAK THE SMOKE SEAL!
ONCE THE SMOKE IS OUT YOU WILL HAVE LITTLE OR NO POWER.
The smoke can not be replaced. New parts will be needed.
This is true for battery and corded devices.
Small electron leaks can seal themselves. If the leak, male or female, persist return tool for service.
ps - use caution wearing tinfoil hat if working near a high voltage lines or going to a fast food drive up window. Insulating w/ a layer of sill seal lowers risk.

smoke test ? you wanna see a smoke test???I just happened to be standing near this when the smoke got let out ....its my favorite HOLY SHID picture and I drag it out from time to time
not much adjustment..... without taking the whole thing apart, this will be mostly a visual check,take the brush caps off ...
make sure the brush moves freely in the holder.....if it is sticking.....use non-metallic SANDPAPER only.....very fine grit, and lightly clean up the brush on a flat surface.there may be some gunk under the brush were it is supposed to ride the commutator ...try to gently blow air thru the brusholders.while turning the motor by hand..
..if this saw is a WormDrive disregard the last steplook at the brushes....are they smooth and shiny or scorched on the edges....make sure the brush is installed correctly and the radius matches the commutator when you put them back incleaning or sanding the commutator is not possible while it is inside the saw...but what you are looking for is..........film: it is what you need to have on any commutator.....Good commutator film is chocolate brown or burnished bronze or black and uniform in color. It is not bright copper or burnt black copper, and it will not wipe off......one factor of good film development is .....humidity......yep.at least 20%RH at 75 DegF or
40% RH at 50 degF..... less moisture will degrade the film , shorten brush life and can cause insulation failure.......which can produce a ground fault........along with a proper operating temp range of around 212DegF we are talking about the motor here.....can any of this be found in a power saw ? Yes,
will you see these things,? maybe......the duty cycle of power tools in construction, tends to destroy the tool, an ideal situation hardly ever occursbut you now have some info that may be absolutely useless,
however, you might keep some of this for reference ____________on the other hand its probably some factory gunk that will burnoff after putting a good load on the saw up for a while

thanks very much. What a great post.
Pigsooie, you are welcome
It's busted. Send it to me.
