If it does, you should see two covers, likely round black plastic with a
screw driver slot, at 180 degrees from each other that hold the works that
retain the brushes. I think my Sears saw uses brushes.
Real hardware stores still stock brushes. McMaster Carr if not.
Had to shim the brushes in a chip conveyor motor last night to limp it along
until I can order new brushes.

By the way, I would really like a bandsaw, but the one I bought
several years ago at TSC would not cut straight no matter what I did.
I went through two before I sent it back and got my current chop saw.
Are they still that was. (The cheaper models?)

Someone stole my chop saw a few years ago. I still thank them. I bought
the $149 HF band saw. So far, it has worked flawlessly, except for a couple
of adjustments here and there. I built a rolling cart for it, and a wing to
catch drops, and bought some roller stands to feed the metal. Mine is
accurate enough for what I want it to do, you may need a more exacting
model.
In my lifetime, I've worn out about five chop saws. They in turn, have worn
out my hearing. I have had metal plucked from my corneas twice, and was
wearing safety glasses both times. I would never ever own a chop saw again,
but that's just me.
With the band saw, you set it, and walk away. If you want multiple cuts,
you can stack together multiples and it cuts more at once. It's not as
quick, but there's far less noise, smoke, sparks, and flying debris. Miter
cuts are better on band saws because the blade drift/deflection is less.
YMMV

If the brushes are that close to gone you should hear the speed
changing and odd sounds even when not loaded.

All cheap import bandsaws are "kits" and will need to be properly
opened up and cleaned out (they like to leave casting sand inside the
gearboxes with not enough grease to properly mix with) and the blade
guides & alignment fine tuned before use - nature of the beast when
they have to meet everyone else's sales price. They send the raw
materials, you have to turn it into a working saw.
If you are going to chop lots of metal production style, look into
Cold Saws. Looks like a really stout 12" to 16" woodworking style
miter saw, fine spaced but heavy toothed carbide tipped saw blade,
turns rather slow, serious horsepower (2 or more). Doesn't abrade the
metal like a chop saw, actually cuts it.
Cold Saws are /not/ cheap, but they last. Fairly quiet, no drama,
slot appears... You can't just put that blade in a woodworking saw,
way too flimsy, way too fast. And plastic blade guards don't deal
with red-hot chips well.
Blades for them are not cheap, but they are sharpenable many times
and new teeth are brazed on and sharpened to match when they pop off.
But don't let too many teeth fall off before sending it in for rework,
it's a cascade effect failure - if you lose two or three teeth in a
row you can suddenly catch the edge and zip them all off...

Well ... that depends. Back when they were referred to as the
$200 horizontal/vertical bandsaw (and prices were already falling below
that), I got one from MSC which turned out a lot better than others that
I have seen.
The motor can run a long time and stay cool, while it is common
for the original motor to burn up on a long cut.
The blade guide assemblies on many of them are bent-up mild
steel, while the ones on this were forgings to which the
eccentric-mounted ball bearing guides were assembled. The difference is
that chips and thick welds on the sheet-metal ones will bend the metal
thus loosening the adjustments over time. This one holds the original
factory adjustment and still works fine after about ten years of use.
*All* of them have a blade tensioning adjustment which takes
pretty much all of your strength to tighten to get it to the minimum
tension -- so until you learn this, you will get your blade wandering
all over the place. :-)
And -- MSC thought enough of this one to put their name on it,
which I think they would not have, had they sold the cheapest version.

And, of course, you can get bandsaw blade stock in rolls, and if
you have a blade welder, or make a jig for silver-soldering the blades,
you can save a lot of money over time.
