Does anyone in this NG have any experience with the threads stipping on the
depth adjustment knob? Double click on the following URL for details:

The unit is 2 months out of warranty. I'm a do-it-yourselfer that has done
only two small room projects with, shooting about a dozen or so rows of
nails....that rows, not boxes!

Two weeks ago the unit had a bad spark plug which I replaced. Now the
threads are stripped on the depth adjuster, so it only shots nails deep.
The adjuster appears to be made of a softer steel than probe. The adjuster
is a bear to replace...need to tear unit apart.

It appears to be a design problem. It looks to me like the size of threads
are too small for the impulse or impact load that the threads have to
absorb.

Of course the tech support is mute on but the spark plug and the thread
problem. When pushed, they give the usual response that I'm the only one
that has reported this problem. The warranty repair shop says they
routinely see the stripped threads problem. At least they're honest.

Question I have, has anyone experienced the stripped thread problem and
found a solution, short of replacement of the adjuster?

Thanks much in advance.
Cheers,
Jim
