Assembly starts with taking two of the metal arms, slipping 3 bolts through each, and laying them flat. The plastic tubes are then slid over the bolt. The instructions say to use cooking or other household lubricant, but I found they slid over with only relatively minor force needing applied.

Next you slip the loops of the ratchet straps over the top bolts, making sure the ratchet handle is facing up. Then slip the remaining two arms over the bolts, finger tighten the 6 nuts and you're done Takes about 2 minutes if you're inept...
They now come all put together,,, and I've got new instructions with 15 pictures They are kinda' small but they are helpful in doing some different tasks. Thanks again Range and CBM!!!
