This is an instance of the salesperson not knowing "everything".
In the old days, the governing spec for rotator capacity was "square
feet". About 10 years ago, Hy-Gain instituted their Effective Moment (EM) spec
which is the turning radius times weight. Soon Yaesu followed suit with their
"K Factor". It's an improvement but obviously not everyone is familiar with
it.
BTW, you can see from your own situation that square footage alone
doesn't work.
The spec 'error' was made by the salesperson; not by the manufacturer
(since they publish the ratings) or the buyer (since he didn't really know
either). I would take my complaint back to where you purchased it - they
should be interested in making it good for you.

Huh? I don't have the Yaesu general catalog to look at but the
standalone rotator brochure certainly has the K Factor as one of the specs.
A mistake was made and some damage done. Hopefully we've all learned
something and it'll get taken care of to everyone's satisfaction.
There is one moral though: Subscribe to TowerTalk to help stay out of
trouble!
