Depends if you are standing the whole time yes but kneeling not so much
No, nails must match the angle of the magazine.
Very long time. This is one of the best battery tools I’ve ever bought. I can shoot several hundred nails through it and barely wear down a bar on the battery.
If it is reconditioned the description will say so, and will have a lower price because of that. Otherwise it is new.
1.25" is the minimum.
The specs say that the nailer weighs 6.3 pounds. I believe that is without the battery, which would add maybe a pound more depending on the battery size.
No, 18 gauge nails will not work in this nailer.
