Hello, I have some problem with this machine. After one hour of use it starts to stall in heavy load. It does not do that every time but randomly it does. If joystick is relased little, rpms raise back.
When this happens, it sounds like motor is pumping up and down because pump is changing load. Like it first doing right and then takes too much load. Still rpm is going down and finally stalling motor.
I have been checking monitoring code 11 (pump discharge pressure input) when this happens, thinking that it stalls because of heavy pressure. It looks like the pressure is something between 150-325. Sometimes that happens if you drive cylinder to end position.
Thanks
