Hi,
I have an older Grove AMZ-66 two wheel drive manlift. It has problems with the basket proportional controls where moving the joystick in either direction gives you movement in one direction only. The movement is a little slower when the joystick is in the opposite direction from what you are trying to command. This odd action does not stay there 100% of the time. Sometimes the joysticks seem to work for a short period of time but invariably go back to the one way operation.
The machine has an "OEM Controls" controller that seems to multiplex the proportional controls into one cable pair to transmit the command down to the receiving controller on the machine. The transmitter has the keypad and plug-in jack for earphones.
I have a service manual for a newer machine...mine is a 205XX serial number and the manual is a 836XX serial number. It was an eBay manual and so I got what I paid for...someone had removed the hydraulics/proportional section that had all the explanations I think I need to troubleshoot this puppy.
I can get everything to work from the controls on the base of the machine. All of the "on/off" controls in the basket work, too. I did notice that occasionally I had to mechanically poke a proportional valve up the butt with a screwdriver to get it to work...so they must be a little sticky.
I checked for a manual with the local Grove dealer in my area (Coast Crane) and they in turn checked with Minnpar....sure, a manual can be had for $499.95. Seriously. This is a "stump ranch" machine, not one that has to work in downtown NYC!!
I'm looking for either some kind soul with a manual who might be willing to photocopy or scan the manual section I am missing (for $) or to make suggestions and help me work to a solution.
Thanks,
Jon.
