help on american kleaner

hello,

i have a 600 gph, 450 psi, two steam gun, diesel fired hot washer built by american kleaner for the army, thing is ive never used it, it runs as i have tested it, but i dont know the normal working temps of this machine or the normal working pressure of it, as i have no info on it just dont wanna burn any one or have an accident with it, i would very much aprecciate any info on it , i ran it at 350 f and stoped it cause steam pressure felt a lil too much maybe im wrong on this, i intend to use it to wash trucks i already do that but only cold water.

thanks.
