Question about Hitachi Tools & Hardware - Others
I've had that happen before and what I found was one of the Staples or nails had misfired and wedged before leaving the gun. read the manual on how to get to it for that particular model and also it might be a good idea to adjust your pressure accordingly to keep it from happening again. If the force isn't set proper then a nail could Jam , block the mouth and not allow any other nails to exit. It's very easy to do and not that hard to fix once you've done it at least once. Good luck.

couple of things there are o-rings inside that trigger assy. they are either pintched in or dry. next there could be internal rubber hoses inside the gun. might need replacing. lastly the hose or o-ring going to the back side of the ram is leaking or broken. here is what i would do. you sound pretty handy with your tools so i would get somewhere clean start taking the gun apart thouroghly noting where everything went and go untill you find the problem. but first i would shoot a couple of drops of oil into the air input on the gun then hook it up and fire a few off and see if it clears up, if not then start takeing it apart. I CAN NOT STRESS ENOUGH....DO THIS ON A CLEAN SERFACE WITH YOUR HAND CLEAN. i chased a leak around in a pnumatic hammer for 3 days all because it wasnt clean on the inside..

SOURCE: nail gun double fires
There is one main part that can be the cause of the problem.
The trigger. Check to see if there is anything out of the ordinary with this. There should be some moving components attached to the trigger itself. Is any part of the trigger touching the button in the body of the gun when safety is not depressed. If the lever on the trigger is pushing on the button, even a little bit, It will allow the gun to fire again and again.

Porter cable makes a number of brad nailers (18 gauge) that very quickly suffer from the problem that you are having. You did not mention the model number of your gun but if it is one of these, (bn125a, bn200a, ns100a) kit # 60061 will fix the problem. It costs between 25 and 30 dollars. Google that part number or order from www.dewalt.com. Dewalt owns the porter cable brand. Before you order the kit, check that the driver blade is not bent and stuck. The driver should travel freely down the cylinder. When you install parts, use Danco silicone grease to lube (availabel at Lowes in the plumbing department) If your model # is different from those mentioned above, please email me and I will recommend a repair.

If the air is coming out the trigger it must be replaced. Depending on the model of gun you will have to replace the trigger assembly or various o-Rings. Find a Bostitch dealer in your area and they will supply the parts you require.

the 601 had a design flaw, in the nose, where the nails hit as the are being pushed forward, the peice was made out of a peice of metal that was too soft, it wore down and that is where you get the double nail problem.
Senco offered a trade in, this was years ago, for a limited time and gave us credit towards new guns, which we gladly did
