I got my PM-932 delivered late last summer - but I'm just (finally) - getting to setting it up now. Do these mills have a tendency to leak? I've been reading as much as I can about the PM-932's - and I'm wondering if I should be doing something like taking apart the head - cleaning it all up - and re-lubing it all with a high quality lubes and then resealing..... before I even start putting the thing into service.
