We have a pw140 wheel excavator here and if you are trying to use 3 functions eg pull in the dipper raise the boom and curl the bucket at the same time then the boom will stop dead until the bucket cylinder comes to the end of its stroke then it will shoot straight up. Anybody come across anything like this before or know if there is a compensator valve i should be looking for
What about the boom raise and dipper in, do they work together? What is the dash number of the machine? It was always like this or just newly happened?
jey_c has the right questions. I would add that we need to know if this machine has the old Dash 5 style open center load sensing or newer Dash 6 style closed center load sensing system.
I will know more early next week i think its a -6. Will reply when i get back to it
