Binwil lift pump problem


New member
I bought a used Binwil TPO 7 lift and just finished setting it up. All the electric works, motor runs, filled with new fluid, but the pump doesn't seem to be pumping. I am thinking that it needs priming or it is shot. Does anyone know how to prime it or if it doesn't need priming how to test?It is a Nihon spindle pump PA 5LA130
