Takeuchi TB240 thumb speed slowed way down

The machine is a 2021 Takeuchi TB240. I bought the machine new and the thumb has always opened and closed a little on the fast side, but today when I started the machine the thumb is now opening and closing very slow. Does anyone have any ideas why it would do this all of a sudden? Thanks for any replies.

Is there a needle valve or a valve feeding the cylinders that has been closed off. Is it colder than usual and is the oil a little too thick. Is the ram in the cylinder bent, or has the packing begun to fail and by-passing oil. May need to tee in a gauge on the base end to check pressure with it activated.
Has something been changed on the display that controls the pressure or flow of oil to cylinder.

Thanks for the reply. I don't know about the valves. I sure didn't bend the cylinder the last time I used it. All I know is that it was working just fine the other day, and today it wasn't. I'll call the Takeuchi dealer tomorrow and see what they have to say.
