jamming nail guns?2/22
What is with nail guns these days? We seem to have problems with all of them from different brands especially the 23 gauge pin guns. They jam constantly and no matter how many times we fix them it seems to happen again. It even happens with the 18 gauge guns. Is there any guns that you all have used that work without this problem? I'm ready to throw all of them out but afraid I'll just get more of the same.
There are four things I would look at:
Make sure you are oiling your gun frequently.
Check the air pressure going to the gun. It could be too much air pressure.
Make sure the pin isn't getting rounded from use on your guns.
Also, it is possible the nails are the problem and not the gun. Some lower cost nails can cause lots of problems or are not compatible with the gun.
Check the brad nails. We had a box of 5/8" 18 gauge brads that jammed every gun we had within the first 5 shots. Opened up a new box of the same brand and the jams stopped.
I agree about watching the quality of the pins, nails or staples. Even then, quality among lower priced guns are all pretty much the same, or so it seems in our shop. Lately I have stopped buying the box store guns and have been ordering better quality through suppliers like Nail Gun Depot. Again, in my situation it seems the higher price is yielding better results, with less frustration.
I noticed this with a Grex headless pinner, the problem was always fixed with oil.
Most obvious cause of a jammed nail gun is hitting something hard, such as metal, concrete, or a faster. I assume that is probably not the issue here. That aside.
When I have this happen its almost always dirty/corroded or low quality Nails. Keep the guns oiled if they are supposed to be, and rule that out as well.
Low Pressure can also be a cause. Think portable compressor with 90 PSI cut in pressure. Might not be enough for longer fasteners, in dense hardwoods, with some nailers. I mention this, because I have had jams attributed to this.
Long runs of hose or fixed air lines will result in pressure drop as well so its not a bad idea to check your air pressure at the tool, to rule out supply issues, and avoid running 300 feet of 1/4 hose from a small compressor with 90 PSI cut in pressure .
I own at least a dozen nail guns. 23g, through framing. Pretty much every brand, ie Hitachi, Bostitch, Porter Cable, Senco, etc... Jams seem to be pretty rare. Above situations, have caused every problem I can remember.
Don't buy nail guns from harbor freight.
