Trying to confirm the pluming of a few lines on a 303 CR, SN-DMA02366.

I'm thinking the 2 light blue lines coming from the manifold valve going to the unlabeled spool on the right isn't correct. And also the orange line from the unlabeled valve on the left going to the R on the swing brake and the blue line from the unlabeled valve on the left going to the P on the swing brake isn't correct.

Unless the boom down spool is open the brake isn't releasing.

My machine is up the mt. at my mill, we have had a fair amount of snow and it's -27 C so it may take me a day or so to get to it for a pic.

That's a bit cold for this Georgia boy. We hit 68F today, heading for 27F on Sunday.

Thanks for the drawing, it doesn't help unfortunately. I have the full hydraulic schematic, it just does not list the lines individually.
