hey all sorry if this is in the wrong section im not so good at know the age of vacuums but i got a blue deluxe convertable (model U400) on craigslist for 5 dollars and the bearings sound quite dry and rough (the buyers didnt invite us in so i had no chance to test- 5 bucks why not?). anyway, can someone post pics of the whole process of greasing or w/e you do, or direct me to another post? also, the handle when locked still leans pretty far back. is that normal? Thanks!
