Your Nail Gun is Not a Hammer
Although it is tempting when in a pinch to use the backs of our pneumatic guns as a kind of hammer or pounding apparatus, don’t do it. This can cause extensive damage to the endcap and seal which, in turn, will cause the gun to lose air. This, of course, will render the gun nearly useless and requiring repair. In short, pounding with your nailer is just not worth it – Use a hammer, or a mallet, or someone else’s nalier. Just kidding. Use a hammer (or a mallet).
