A month or so ago I bought a Porter Cable finish nailer with the pancake
compressor etc., it works great. However I'm concerned about the change in
the noise it makes. It used to make a "wump-bump-shhh" sound when I drove a
nail in. Now its more of a hard "bang" no "shhh" at the end. Occasionally it
will go back to the old sound for one or two nails, but then back to the
It still drives the nails in without a problem, but I'm worried that the
"bang" noise is a sign that there is a problem with the nailer and that I'm
doing damage to it as I continue to use it.
Has anyone had a similar problem...is this even a problem?
I've been pretty good with the oiling. I've been using it two or three times
a week for the last month and I think there was only once or twice that I
didn't put a couple of drops in.
I'll be using it tonight, I'm going to try the slower trigger action that
someone else had suggested.
It's not out of the ordinary. IME If you run the gun slowly, and keep the
trigger depressed until after the nail is completely driven you should get
sound it used to make. the bump shhh thing. If you run the gun faster, and
release the trigger before the nail completely sets, it will make the
different bang sound. I don't think either way will harm your gun. --dave
