Good morning,
My 40ha will not raise the boom as it should very slow to nothing at all. I can increase the rpm's and get some movement or activate the 12V emergency motor and it works pretty good.
1. how / where do I check for hyd pressure and at what rpm?
2. what valve stack handles the boom up / down? I can't see the dang schematic print
3. the boom down seems to work ok it's just the up and now the tower up is moving slow too.
I've set the rpm for the ground, platform and high speed per the manual (sometimes she wants to surge tho)
rotate, tele, platform rotate and tilt, steering seem ok.
And I have a bad or jacked up PQ controller one direction it's good the other there's a very small sweet spot or nothing.
Thanks
