Kubota U35 Display Error - Hydraulic Thumb

[jjchavez]

Hi there, I bought a new U35 about 3 months ago and am getting close to my 50 hour service. About a week ago, while digging out stumps I noticed a warning light when I click the accessories display button to activate the hydraulic thumb. I am not sure what it is telling me. See the attached images to see what I am seeing. The thumb still seems to work just fine, the warning light just annoys me because I don't know if it is an indicator of something wrong or me just not knowing how to reset it.

Any help would be appreciated...the manual doesn't say anything about it. It talks about how to relieve pressure in the auxiliary system and I've done that but doesn't seem to make a difference.
