I have recently purchased a "used" Porter Cable PC7751 hammer drill. I put
the used in quotes because I purchased it from a person who never once used
it - as in the power cord is still wrapped in the factory tie wrap. In any
case there is a small amount of oil on the top casing of the drill which has
obviously leaked out after years of sitting on the shelf waiting to be used
(It was stored "sideways").
Should I be concerned about this? I'm wondering if I should bring it in to
a service center to have a look at it before I use it. The manual says
that oiling and replacing the brushes should be done by a qualified service
center (which I have one right down the road). Am I being overly worried
about this? I just don't want to burn the thing out if all the oil that is
supposed to be in it is no longer in it.
