I have a P180 UG3 and i can assure you there is no info about adjusting the shocks in the
Owner's Manual. And I am familiar with my toolkit, i don't think there is a tool that can be used for this purpose. I have no interest in adjusting my shocks. Was just high-lighting the original poster's plight. The instructions are there however, on page 23 of the
Service manual, but that doesn't describe the tool either. I hope the 150 & 180 have a similar shock setup.
