Dewalt DWHTTR510 Stapler Brad Nailer Multi Tool

I purchased this a couple years ago. I had issues within a month after. I have used the recommended staples but the gun would jam up. I finally figured a work around and it's been ok for most part till today. Somehow a row of staples became caught under the loading assembly. I finally managed to dialog them but in the process the tension spring became unhooked. I can't find anyway to take it apart to reconnect the spring - if I can. I will play around trying to get it reattached but it will probably hit the garbage. The time I have spent trying to get it to work, well if I was working during that time, I could have bought many more. It's too bad as I have other dewalt tools and they have always been reliable.

I wanted this for light weight upholstery projects. A big disappointment. Jams constantly. Often inserts one side of staple only, while the other side is either flat against the fabric else curly and mis-shapen. Occasionally, it will insert a staple.
