Bobcat 331

[TJHVAC]

The 331 mini ex loses operation of all hydraulic controls after 1-2 minutes of lowering the safety arm. The engine continues to run just no movement of any kind. I just had the control panel rebuilt due to problems and now this. The control panel flashes the exclamation symbol and I have flash codes of 06-13 & 08-21.

Now that I know what the codes mean where should I start first? The machine will operate for a minute or so before losing function. I don’t think it’s running hot that quickly for error code 08-21.

how do I check the engine speed?

 

[laurencen]

on the display does it show temperature and rpm? you could have a sensor defective, does speed show up and change when you try to throttle? what temperature is displayed? do you have a way to measure it

The temp is at mid range. No Rpm on the display. No speed either. Throttle goes up and down fine from low to high.
