How do i restring the Ariens st 622 string trimmer

Cut two pieces of 18" commercial grade line - one to mount on each side. Look at the series of holes, two on bottom of rotating head, two immediately above but on outer lip of plate. Go up through the bottom two holes, even up your piece of line (like when you are putting in a new shoe string in a pair of shoes) and cross over then out through the top two. All done. If you are using an adequate grade of commercial line you can trim for hours over the roughest of stuff without worrying about restringing.
