Volvo 160C Thumb auto closing and opening.

My Volvo was working perfect yesterday. The new guy got on it and pushed some buttons and now when my thumb toggle button is pressed to close the thumb it closes all the way instead of only moving when the button is pushed. And does the same way when opening. It dosent start/stop when I let off the button it goes all the way one way or the other. Any help is appreciated. I don’t think anything is malfunctioning, I just need some advice on what steering in the hydraulics menu or work tool menu to use to correct it. Thanks guys.

Good day
Your post describes what I know as proportional control as best I recall you can adjust on the screen from On/Off to proportional, has this been adjusted ?
Kind regards

Go into profile for your hammer, change setting from toggle to push.
