I have recently been able to get my model 2040 to start. The only way I can keep it running is to bypass the hydraulic charge pressure switch at the control valve. I have replaced the pressure switch and no change. The switch is supposed to open when pressure is >80 psi, and I used my air compessor and verified the switch does close at that level. I know there is oil where the swich screws into the block, but no current way to measure the pressure at the block. Obviously, I do not want to operate the machine with the safety bypassed, so I need to figure this out. Any suggestions?
