Starting on with a new company and a new machine. Their previous operator neglected to train a new operater before resigning and left them with no one that knew anything about the machine except how to turn it on and off. If anyone could point me in the right direction as to where I could possibly take a class on the Doosan Puma 400 or maybe where I could get a training book, it would be greatly appreciated.
I would contact your Doosan dealer. They may offer classes at their facility, or have an engineer who can give you on-site training. Contact info for the closest one I could find to you is in the attached jpg.
