On every page of manual, it clearly notes the need to have machine at operating temps...specifically, the hydro oil at 150F. I adjusted the main relief valve on the manifold! My first play with hydraulics. I don't count the myriad of hoses I've replaced or ram tinkering as hydraulic work. I'll admit, I was a bit daunted by all the hoses and valves everywhere...slowly, I am starting to understand how it all works. Was cool being able to adjust pressure...and it was ridiculously easy. Might even move Bobby into a new weight class....lol Ok, maybe not... On mine, the main relief is just behind the main diagnostic port. Loosen locknut, and use an allen key clockwise to increase MR pressure. One full turn equals 500psi, so I didn't have to turn it much to get back in the zone (bumped it up 100-150psi). The result was the bucket now overpowers the thumb (back to normal), as it should. It didn't before, and that was my first clue something was wrong. I'll get around to the oil changes later....lol BTW - if they spec'd engine oil 10w-30 as a substitute, one would think most name brand hydraulic fluids would work. Just getting the right weight would be key...imo As far as additives go, I would be inclined to stay away from exotic hydraulic oils...just stick to the big brands that don't have some new super duper additives. Really would be nice to get the specs on the pump though...the pump specs are another key...they will tell me what oil it likes to chew on and keeps the pistons happy. As for the rest of the hydraulic system, I doubt they'd mismatch the oil requirements from the pump. Looking forward to firing up Bobby and seeing how the new pressure affects performance.</p></blockquote><p></p>
