As an intermediate DIY'r, I am surprised to be having
trouble with my new circular saw. I am attempting to cut through 1''
stair noses, but my brand new Skill 7 1/4'' saw can barely cut through
the wood and smokes excessivly. I finally used a jig saw to finish the
cut and noticed that the wood was black from burning.
Any thoughts? I've never experienced this with my 18v Ryobi cordless
saw, and I use it pretty hard. This saw even smoked while cutting a
1'' bamboo stair tread, which the Ryobi cut effortlessly.
Thanks in advance,
I'm pretty sure that it is not. The arrows on the blade are going the
same direction as the arrow on the saw, thus the teeth are pointed
upwards at the front of the saw (if that makes any sense). Anything
else that could cause this? Otherwise, its back to the home depot and
pray they return it.

In a circular saw the points and openings of the teeth should point up

Noticing that you have already replied that the blade appears to be on
correctly I must ask if you are using the blade that came with the saw?
The usually aren't worth the time it takes to install them. Buy a carbide
blade of the proper size and see how that cuts.
In addition to what others have said, occasionally wood will warp when
cut in a direction which tightens it at the trailing edge of the cut.
This "clamping" effect can cause a problem like yours. Or, if you are
trying to do a curved (jig saw) cut, that will burn the wood, too.
But I would go with a new blade, a carbide one. I use a carbide blade
for all my work; normal rip or cross-cut blades do not last on anything
but light weight cutting. --Phil
