Take the balls out and in the cash box with the coin door unlocked. Have the head folded down with old rags on the rails between the backbox and the rails and strap this down so it can't bounce around so the translite / backglass can't come loose. Definitely strap the machine down to a pallet as due to the weight no one is going to manually pick it up, if you don't they will try and drive the fork tynes under the machine. Once fastened to the pallet lots of bubble wrap, (wrap the legs and fasten to the side of the machine / pallet then heavy cardboard, followed by some cling wrap and water proof the address and your address so no getting lost under the cling wrap and taped in place.

I have only sent a empty cabinet but have received a few this way with no damage. Sorry didn't take photos, too eager to open.
