Just got the Cube and can't seem to adjust the width tension. The "manual" says to "adjust the width of the Flip-lock by adjusting the small wheel, between the fixation socket and the Flip-lock lever. First, push together the Flip-lock device and adjust."
The wheel doesn't turn either with the lever fully open, half open or closed whether or not I squeeze the two sides of the "Flip-lock device" together or not. I'm reticent to use a screw driver blade on the wheel.
Any guidance would be hugely appreciated!
