The manual is correct just a little bit vague.
This adjuster is a small master cylinder that pushes hydraulic fluid through the little black hose that then moves valves in the shock. This changes the damping in the shock to make it a firmer or softer ride.
Just so you know we have not sold this shock since the middle of 2014 because our new JRi shock does not require it.
Anyway, here is how to adjust it.
1. Loosen the set screw so that the knob can be completely removed.
2. Turn the shaft counterclockwise by hand until it out as far as possible. This is the softest position.
3. Bounce the rear suspension of the trike several times to get the shock valves to settle back to the soft position.
4. Turn the shaft clockwise (in) by hand to take out any slack. Go until you start to feel resistance and then go about an 1/8 of a turn farther.
5. Reinstall the knob pointing in the 9:00 position or as far counterclockwise as it will go. It has a pin on the back that limits how far it can turn.
6. Tighten the setscrew and you are done.
9:00 is the softest position and 3:00 is the firmest position.
