I got an Ego string trimmer, and it was great except it spun in the wrong direction. I looked online and I couldn't find any way to reverse it so I opened it up and figured it out myself. To reverse the spin, you have to undo a few screws on the battery area of trimmer and pull the cover off. Then you look for the blue, black and white cables coming from the shaft of the trimmer. Pull them out as far as you can. Look for the shrink wrap and cut it off the blue and black, underneath is a two part crimp that connects the cables to themselves. Uncrimp the middle of them using needle nose pliers and a bit of time. The cables should separate. Then take the top half of the black(coming from the battery), and the bottom half of the blue(coming from the shaft, it may be a green or turquoise), Insert the male into the female part of the crimps, and close them together using pliers, wrap in electrical tape. Do the same for the blue. Then route the cables so the cover can be closed, and tighten the screws down. I advise you take pictures so you can look back to try and fix anything you break. I am almost certain this voids any warranty.
