[R-390] re: Dangling PTO

[Al Parker]

Hi Ken & Craig,
    I don't know why I haven't had any luck with dessicating the small
tubes in the PTO's.  Maybe I didn't get them hot enough, I've tried a few
times.  I know it should be reactivateable, just figured it was too old.
    Craig's experience is the first I've heard of the tube breakage &
corrosion problem, but it sure makes sense if it does break, the damage is
worse than the cure.
    In the environment most of us have nowadays for our operating area, I
doubt that it would be much needed, and don't wory about pitching it out.
If we had bad conditions, like maybe in a storage shed, there's not enough
of it to be effective for too many cycles I suspect.
73 all,
