Todd V: I do not consider your comments rude. The position of the hose caused me problems trying to break loose the fitting. Instead of spending a lot of effort to try and get it loose I just decided to plug the line at the valve body. For me, knowing people in the hose business it would be more like $20.00 for the hose but getting it apart was the issue. In 8 years I have never used the aux. and I cannot see me using it in the next 8 years. If I really need to use the aux. I will just run a hydraulic hose from the steel line at arm to the fitting at the valve body. I did not change the filter but it has only about 300 hours on it. After changing the filter last time the light still came on when cold as it does now since changing the switch. You are correct in changing the filter, but my concern was the last time it was seized on so tight I had to totally destroy the filter to get it off and was nervous of having the same issue again...so I took my chances. The fittings are JIC and there are at least three on the machine #12, 10, 8 and maybe 6 as well. The aux. is a 3/4 line with a "1 1/4 nut = #12 JIC I now have a set of caps and plugs for all sizes on the machine in case of needing to replace a hose on a jobsite. Brian
