Here are the install photos. Close up is of the adjustment valve. Can't seem to get it working yet, no power assist. Tried turning allen screw adjustment both ways, cracked open lines till no air came out, no help. Notice that I have to re-route the loader return so the cylinder can fully retract. Several ideas: 1) remove adjustment screw to check for debris. There is no info on the parts inside, so hopefully nothing goes wrong 2) check pump output with pressure gauge. Again, no info but I should expect at least 800 psi? 3)Test cylinder movement with compressed air. Post any of your ideas please.
