I'm going to get yelled out for this, but here goes how I would lift it.
I would use a webbed strap around the spindle, behind the chuck, and the other end of the strap around the tailstock. A single loop, not a choker with a twist around each end and it can't move or slip. Of course, the tailstock should be moved to wherever the machine will balance.
I feel this is safe in view of the light weight of the machine, and it's rating for a workpiece. There won't be any shock load on the spindle, and the amount of stress from lifting the machine (330 lbs I believe) is not going to damage anything. You'll put more stress on it while working that you will lifting it this way.
I have also seen, but not too crazy about, people simply slide a bar through the spindle and strap both ends of it and hoist away....on much larger machines. The people doing it were well seasoned men who had move a lot of machinery, and I do not know of any harm done doing it.
