Bucket truck hydraulics mushy in the cold

And ran the Altec TA40 this morning at 28°F and the bucket controls felt a half-second behind while setting a 45’ pole after digging with the auger — anyone else see this lag? Filters were changed last month and the digger derrick on the other truck feels normal, so is this just fluid weight or a valve needing attention?

At 28°F, that ‘half-second’ lag screams AW-46; try AW-32, or cycle hydraulics 5 minutes first.
