I moved the lift into final position using a bottle jack horizontally to slide the base around. Since it’s recessed in a hole, there were convenient edges all the way around to push against. I centered the ramps in the garage door opening and adjusted it from front to back to that it was easy to walk around both ends of the lift. It ended up within 1/8″ from where I marked its position on the slab from the measurements I took from the 3D modeling I did.
I used Simpson Strong Bolt 2 anchors that are 6″ long instead of the 4″ anchors that came with the lift. These will have far greater holding power.
