The first thing  to check in both of these cases is how long has it been 
since the instrument has been defrosted?    A total warm-up, cleaning, drying 
and cooldown.  It could as simple as ice in the lines.  Also, make sure the 
lines are clear of debris.  Let me know how this works.

 Our only problem with the vacuum is that it doesn't turn off any more, but
 more of a noise nuisance than anything else It works, it just doesn't shut
 off when the head is up.  We use the Microm 505.
