3-Point Hitch 3 point wont raise

[Stihlrunner]

Hi

I have a Jinma 284 that I've had a couple years. It's developed an annoying habit of the 3 point not raising. It seems to be after it sits awhile and is cold.
Fluid level is up, adjusting the speed control doesnt do anything.

It will lower but no raise. Raising the rpm's doesnt help. Sometimes it works just fine.

Any ideas?

Filter been changed? Check pressures with a guage.

auxiliary valve open just a bit?

Talked to the dealer I bought it from, came home and drained out the AW32 and replaced with ATF, changed out the 50 micron filter for a 30 and it worked great!
