Describe the problem:
The piston that drives the seal jaws is freezing again, and is getting to the point where it's doing it daily. We've been able to unjam it by temporarily raising the pressure, but cleaning it out (and maybe installing some sort of cover to protect it?) would probably be better, and it would be a good opportunity to check for defects.
I'd like to recalibrate the safety sensors for slightly higher pressure anyway, since it seemed to help with the issues we were having earlier in the week, and it would make it easier for the sealer to unjam itself.
