Can anyone explain how air is purged out of the 360 hydraulic system? The manual says to cycle the gear many times and this will be taken care of. Does the trapped air vent to atmosphere through the cylinder seals? There's no return back to the pump. Maybe it doesn't matter if there's some air in the system. It might help in troubleshooting if I understood this better. Ed de Chazal Rochester, Michigan
