Sounds like battery is fried.....do you have another tool that the battery fits?
SOURCE: brad nailer not firing nail...can hear brief air noise upon pulling the trigger
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.
SOURCE: Bostitch nail gun loss of pressure, won't fire nail
Hello. I can help you. The nail gun you have uses 18 gauge brads. I would use only original Bostitch 18 gauge.
The one MM of difference you mention is the reason why you do not have the pressure you did have. Get rid of those 31MM brads and get the 18 gauge. Home Depot carries the Bostitch line. I would go there or to homedepot.com
SOURCE: NAILER WONT FIRE NAILS
DO NOT USE WD40 . Is The Nailer fireing? If Not check the micro switch by the fan . Make sure it is pushing on the switch.. Otherwise bend it a little
SOURCE: nail gun wont fire
First - the air pressure has to be high enough - check the regulator on the tank to make sure it is delivering in excess of 60-70 psi (which I am sure you have already done).
If you have dry fired these guns (i.e. shot them off with no nails in them while you were lubricating them maybe) the mechanism inside could be damaged. I had that happen to one of my nailers (same brand). That was when I learned not to dry fire them...
Since both of them are not working though I would be more inclined to look at the air supply first.
SOURCE: IM250 Paslode straight brad nailer, fan wont shut off
My paselode was doing the same thing, and I followed all of the cleaning instructions, but the problem continued.
If it was left alone for a minute, it would fire again, so I removed the cover over the trigger assy, and checked the spark plug wire connection. The trigger came out, and during reassembly, I noticed that the electrical switch was hanging, and slowly pushing back out.
I cleaned and lightly spray/oiled the switch pin, and voila.........works like a charm.
