Well, I haven't measured it, but it's somewhere around 14.5k according
to Husky. Anyway, I can verify that it's fast. But, as I've learned,
it is not tolerant of even a slightly worn chain. I think I'm going to
have to buy at least one more chain in order to make it through a day
without having to stop and sharpen.

I think it is not RPM (spinning) Chains saw generally have a
direct drive and the drive wheel is fairly small, maybe a
max of 4" in diameter (about 13" in circumference. Don't
know what your bar size and chain are assume an 18" bar
which makes the chain at least 44" long. So, divide 44 by
13 = 3.4. Your engine would be turning 3.4 x 15K or 51K.
Never heard of a chainsaw engine that could rev to 51,000
rpm. Could be wrong, but that would be one hell of an
engine.


I didn't mean to imply that the CHAIN spins that fast, but rather that
the engine is turning at that speed. Husky says 14.7k max engine speed,
which is a lot less than 51k but still faster than many saws. In any
case, I can tell you that it smokes a dull chain in a hurry. :-)
