Finally using the S160 I bought to remodel my yard. My question - I have to push the "Max flow only" button to get the jaws of my 4 in 1 to stay always open or always closed. When I do this it seems to alter the right "tilt" pedal so that no matter if you heel or toe the right pedal the bucket only tilts one direction. What am I doing wrong? Be nice, I'm a complete novice...10 hours on a Bobcat.
