Quoted from Mfsrc791:Take legs off and wrap cardboard all the way around it. Put a ratchet strap around the cardboard to hold it. Then you can drag it to the edge to the stairs and let it tetter over and slide it slowly down till it hits the bottom step.
Then if needed tip it on its back and pivot it around till you can bring it out the rest of the way.
That how I get all my pins in the basement myself
I do them this way as well. Works like a charm so long as you don't slip. If you do, you have a freight train on top of you....kind of like dating Rosanne Barr.........
