I found that placing the ramp on the lift was a little fiddle fook because you have to kind of do it "blind". So painted the matching triangles to help me align it. But it it didn't really help.
THEN I took a closer look underneath and found large burrs on both the holes in the deck and the pins on the ramp. I gave the holes a generous countersink and ground dull points on the pins. What a difference.
I also pop rivetted a a piece of 1 1/2" ABS pipe with a slot cut down it length underneath the deck to make a nice holder for the foot pump pedal
