I've played around with the punch setting with no problems. This is on my HW80 though, if that even makes a difference.

Just being curious, have you tried 0 punch or 0 timing?

Haven't touched the timing. And I usually increase the punch control.

Hey Brian, any recommendations on what to use to clean off the aftermath?

It must be pretty noxious, the steel components have gone rusty brown, even
the black hardware is affected.
