just got machine need to switch control pattern
Expert:  Dan replied 1 year ago.

Ok, If there is no pattern change valve behind the cab you will need to swap some lines at the pilot manifold behind the cab. What you do is trace out the circuits from the main control valve and tag each (Boom up and boom down as well as Arm in and Arm out) There are pilot lines from the manifold to the control valve to shift each side of the spool for each function. Once you tag the pilot lines that go to each function you then swap before the manifold the small pilot lines. Swap boom up with Arm in and boom down with arm out. Let me know if you need more help
