Mr. Sim, thank you for the detailed reply!

I will of course be ordering the replacement/service parts I will need from you, in recognition of the time and effort you have put in to these questions. I presume you ship worldwide?

Is it possible to confirm this is a heavy duty unit from its ID plate? An dif it were in kPa already, how high would the numbers go? Once I know this I will know if I need the decals for the wheels- as I would prefer PSI.
