How have you installed nozzle? Mine seems to be OK, but it starts to move and then sprocket makes it shake and hose looses. I have tightened bolts and as I said, everything seems to be OK.

I`ll try to put nozzle into other position and reroute oil line.

Wich settings do you use?
I have table 16 programmed and it feels lean?
At least at rainy day on gravel.
