McHale high speed wrapper issue

[icanshootwell]

When the wrapper slows on a completed cycle it spits out a bit of oil from the blow off valve, any body know why it does this.

 

[robo]

are you running the wrapper through constant pump on the spool valve . if youare try turning oil flow down a bit ........also check the return snap on connector both male and female are in good order

Is the wrapper set up for open centre or closed centre hydraulics? Does it happen on a certain tractor or different ones.

I had it on a fendt this morning because the usual tractor had a puncture, it's a McCormick and I have not noticed it before.
