LS180 Service Manual

I just bought a 2003 New Holland LS180. I have a hydraulic temp sensor light on. The display shows 255 degrees F. This happens as soon as the skid loader is started. I believe the hydraulic temp sensor is bad. My issue is I can't find the sensor. The dealer says it is on the bottom of the hydraulic reservoir. I have dropped all of the access panels on the bottom of the machine, but can't locate the sensor on the bottom or the side of the hydro reservoir. Does anyone have knowledge of where this sensor is? Also, does anyone have a service manual you would be willing to share with me? Thanks in advance.
