I have an S300, last week I went to use it, raised the arms tilted the bucket down, it tilted and stayed there. The pedal feels like there is no range to push down with my heel and nothing really happens when I go toe down even though there is some range there for pedal movement...the bucket just wiggles a tiny bit. Along with this issue, when I raise the arms to a given point and return the pedal to neutral, where the arms should hold the position where I stopped them... The arms will now settle down a few inches instead of staying where I stopped them. Any guidance would be appreciated.
