HI, I'm an amateur to the skid-steer scene and I wouldn't be well versed mechanically. I have went to view a Bobcat for purchasing, its at an auction. All was running fine when I was test driving however once I hit the auxiliary switch (no attachment was attached) the engine started doing a dying in and out sequence. When turned off and started again, this continues. It shows the following codes: 02-17 Hydraulic Pressure Filter Not Connected 07-21 Oil Temperature in the hydraulic system is higher than the maximum allowable. Both Hydraulic Red Warning lights are on, one is constant and one is flashing. I dipped hydraulic Oil and it wasn't showing on the dipstick. Does this sound as simple as No Hydraulic Oil in the machine or is it signals for a more serious problem. As there was also a hose going to nowhere which I thought was suspicious ( I thought this hose would be out of the hydraulic tank, however I'm not sure). Is this where the filter is meant to be?
