Oh /forums/images/graemlins/blush.gif.....
....in THAT case, maybe something IS wrong if it is bypassing before the full range ( I thought 5 was the highest, too).
Does it go any further than 7" while hissing OR does it stop at 7" and hiss?
I can't see the label clearly from the picture, but setting #6 is a different color - could that have something to do with it/what does it mean?
Under my seat, there is a drop-speed control that controls the speed at which an implement drops - yours probably has it too. Maybe it is mostly closed off - implements would drop slowly, too. Maybe messing with that will help. /forums/images/graemlins/confused.gif
I'm at a loss now.....
Let us know....
