Used mine to cut Dodonea wood. That stuff is harder than diamonds and the blade holder snapped. I'm pretty sure mine is under warranty so even though your video is very clear even to a mechanically challenged person like myself I think I'm going to search for my receipts. We'll see. I feel better knowing that I can watch this for guidance.
Nice, 🎉 I use mine to trim tree branches and brush. I made the mistake of trying to cut a 4x4, and the blade holder cracked in two. I guess it sawzall except 4x4's. I have a much older model, and hope I can figure out how to open it up and replace the holder.
