I have a JLG 1930es lift. It seems as if the switch on the hand controls is not working, the ones that switches between lifting and driving. Sometimes it will just lift even when I have it on the drive side. and most of the time its not going into drive mode at all.. Any ideas??
It's probably just a bad switch, which is replaceable, you can test your platform control module by switching it with the control from another unit. Your local lift rental may let you use (or rent) one of theirs temporarily to test your unit. They also might let you bring in your control module to test on one of their units, if it is something beyond the switch. My local Sunbelt Rental has been very helpful with this kind of thing.
