Bobcat S175-- error code 05-22 Hydraulic Charge pressure Low

So as posted in another thread... I just picked up a Bobcat S175. It's got a warning light on and giving me a 05-22 error code, saying Hydraulic Charge Pressure is low. The machine works well.... no issues with anything I've used it for. If it does indeed have low pressure... if everything is working fine, am I going to hurt anything to continue using it?
Searching around the internet for info, I found I should remove the sender and check the actual pressure to figure out if I have an issue...
