Reduce PSI in surface cleaner?

[ACSTravis]

Hey guys,

I was wondering about using my Big Guy surface cleaner on decks. We are just getting in to doing decks and I have a 3500 PSI hot water super skid ( I know not to turn the burner on wood) and was wondering if I could replace the nozzles and tune down the PSI to make it safe to work on decks with. I don't know if people use surface cleaners on decks or not. Thanks for any help.

Thanks,

there is a nozzle chart but i am lazy i usuall just call the guy i buy my stuff from and tell him what i am doing and he sends what i need ,i would say no more than 700 to 1000 psi
