Ken,
I have one of the Huskie electric chain saws. I burned up 2 motors in
it before I learned that you have to let it cut at its own speed and
not to force it. They were supposed to be putting in an overload
circuit that would trip if you were pushing too hard. I wasn't the only
one having this problem. I have about 3 years on my saw now, and no
problems. Your saw may have this feature.
