AC Runs warm when using hydraulics

I have a 2017 Kubota KX040-4. The AC runs cold if I'm not running the hydraulics. Once I left the safety bar you can feel the air get colder. Any ideas?

    I don't know your system but it sounds a bit low on refrigerant if your hydraulic oil cooler and air conditioning condenser coil share the same cooling air supply. Especially if the oil cooler is forward of the air conditioning condenser coil.

    Maybe electrical issue? Some wires shorted when you flip the bar down and the voltage to compressor gets cut out?

    Stacked coolers that can certainly happen.
