It looks like JIMBO, who made this boom-mounted saw setup, is running a Grand L-30. He seems to be
reducing his pressure to the saw with an AUX valve set to a relief of 2200psi. The Stanley CS06 he is
using is a more modern version of my old Stanley, a CS07.
He is also running a check valve in order to avoid damage from reversing the hyd flow. I do not think
that is necessary unless you reverse the flow, then try to cut something.
