Summary: Does not jam much. Used this for a lot of general framing work. Drives through anything, good adjustments. I've used it to the point of failure, and found parts easy to get from Makita, and quick to arrive. Highly recommended.
Summary: A brilliant nail gun, which came well packed and in perfect condition. My concerns would be the perspex magazine coupled with the lack of a carry case and a very poor black and white manual. Makita make exellent tools but they could do with producing glossy colour manuals. I, like another reviewer had problems sourcing nails, I went on to Stanley-Bostich's web site and found that there nails were compatible.
Summary: This is the best framing nailer I have ever used. It's light, well balanced, has plenty of power and very versatile. The only complaint I have is that I had a hard time finding info on the nails that it would except. I still don't know if I should be using the smaller diameter siding nails or not; I installed about 800 sq. ft. of siding with it without a single problem, so I guess it must be okay.
