Calling a Grove AMZ66 a "buggy" is being kind. Grove has made many good products over the years, the AMZ66 is an exception. These machines were one of the early machines where Grove began converting analog signals at the platform controls to digital signals, sending it down the boom cable to lower control box, then converting back to analog signals going to valves. This is all done with complicated pc boards and cirucits. The situation you describe is not unusual with these machines, they truely have a mind of their own. I have seen these models do some quirky things. Personally, I wouldn't trust one to raise me in the air. Not that it would drop me, but that it might die and not start again, I simply don't trust 'em. ;)

Sorry, can't help with that, been too many years since I worked on one. Even when I was working on them, the AMZ, I was working on one with problems and even Grove factory tech's couldn't tell me what to do with it. Maybe someone will jump in here and offer advice. Otherwise, I suggest going to a rental store and get a JLG to do the job.
