How do you thread a ford 532 wire hay baler?

Run the twine out of the twine box and through the guide next to the needle. Then run the twine through the needles and tie it off somewhere. When the knotter trips, it will inject the twine into the knotters and it will be threaded. If your baler has been sitting for awhile, it might take a few cycles for it to start knotting properly due to rust. for starters if it's a wire baler it doesn't have twine or knotters; it has wire and twisters. but it's true you thread it through the guide holes in balewire box, down through the sheaves, up over sheaves just before the needles and across the top of the needles then tie it off to the brace just like a twine baler. be careful, make sure it's centered over the top of the needles. after it makes a cycle you should be able to see if it picked up the wire and has held it in twisting grippers. it is held in these until the wire goes around the bale, then it should twisted and cut. make sure sheaves that wire goes through are lubricated with wd40 or something similar. i bought my 532 about five years ago and it does a good job. i think you can still get a manual for this baler from your Ford ag dealer.
