Not owning a PTR32, no advice as to that particular model. However, from owning several other PTR's I would say CLEAN IT THOROUGHLY, CHECK THE BOLT GAP, then SHOOT IT HARD!!
You should continue to check gap after each sessions (for a couple hundred rounds at least) to be sure it's stable and keep on shooting (checking gap occasionally). PTR seems to have ironed out most of the problems with their guns now, with occasional exceptions. I think they are the best thing going today (EXCEPT FOR GENUINE HK's) or GOOD kit builds with QUALITY parts. I just got a new G.I., but I almost got the PTR32 instead. I just decided the G.I fit my style better and I could shoot instead of buying a different caliber.
