I just purchased a 2005 Bobcat T190 and since I don't know what hydraulic fluid is currently in it or how what condition it is in, I would like to drain and replace it. The manual says to pump it out of the reservoir tank, however the specs say the the system holds 8.5 gallons and the reservoir holds 4.8 gallons so by doing this I would only remove around a third of the fluid. Is there some easy way to get more of the fluid out so that I replace more of it? I expect that the more new fluid I mix with the old, the better off I am. I assume I could pump it out the auxilliary connection, but I worry about pumping out too much and damaging something. Any ideas? Thanks, Paul
