I have a Bandit 1250 chipper with a 200hp Cummins. It seems to me that the feed wheels lack power. I also have to crank up the RPMs before I have any hydraulics. I'm new to chippers, so I don't know what to expect. How do I determine if the feed motors are shot or if the hydraulic pump is shot? I have no hydraulics at all until I get the rpms up to 2000. This makes me think I need a new pump, but I don't know if worn feed motors would cause the same symptoms. Also, where can I find a maintenance/repair manual for this machine. I called Bandit Industries, but all they could give me was a operators manual (more of a safety manual). It was no help for maintenance. I would like to find a manual on how to trouble shoot the hydraulics, the autofeed system, etc.
