Have you tried the "800" number on the Flushmate label? Loss of air pressure may mean there's a leak in the cartridge, air inducer valve, or possibly even the tank itself.
The handle-shaking thing typically means the handle and rod are binding up and holding the cartridge down after the flush or that you need to increase the clearance between the rod and cartridge cap.
Flushmate tech support should be able to help you identify the cause of the air loss and advise you on the cartridge cap adjustment.

Good luck.
