Have you kept it properly oiled? It might be jammed because it's too dry.

Stuart - this sounds like an air problem - you should perform the following test. With the air nailer close to the compressor you must monitor the airpressure after the gun fires. it sounds like the air is not gettting through diapram fast enough or there is a blockage in line. Blockage in line is not suspected for the following reason . It sounds like the air hose is holding enough air to fire 2-4 nails and then you must wait for the line to fill up again and then it fires ok. The pressure regulator out to the line controls this and they do fail. try this test and report back to me - I know I can solve this for you as I have extensive background in compressor and the like.

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: My finish nail guns, 16 ga won't fire.

There is a little plastic piece inside above the trigger...usually this breaks. It touches a microswitch when the cylinder is closed all the way, allowing the nail to fire.

Hitachi nr90ad framing nail gun fires one nail then will not retract fully and dry fires. Have to push firing rod back manually.
Have you disconnected it from the air source and deep cleaned the nail gun? Sometimes even a tiny bit of dirt can block the rails the rod runs in. Once cleaned add a small amount of oil to the rod runners.

I have a hitachi nr90ae that will not fire. Depress nose and trigger and gets nothing. What's next?
Remove nails and air supply. Firmly depress safety foot against work with trigger depressed and make sure that firing pin is pushed all the way in. If firing pin is being activated by safety foot most likely problem is stuck cylinder or head valve. If the gun has been dropped the cylinder my jam. Remove the head and make sure that the cylinder and or headvalve moves and that the driver is not stuck in place. Good luck

Driver pin on hitachi nr90ae fell out and apears to have sheared off.
Just as a matter if interest, were you using the tool in soft or hardwood? This is something that only happens if repeatedly used in an extremely hardwood like Ekke or similar. Did Hitachi resolve the problem with you?

Why does my Hitachi nv45ab gun double fire nails?
This gun should be bump-fired only. Do not place the gun on the work and press trigger. Make sure that the safety spring is in place and has good tension. The spring helps to push the foot off the trigger so that it fires once. You could also adjust the screw that pushes on the firing valve. Turn in or out several turns till head of nail is correct when bump firing then lock the nut. The safety foot fits rather loose on the gun and should still work ok but can get so loose that it falls off the nose. Good luck

Nail gun problem
This is a bottom fire tool. (NV83A2) You need to hold the trigger down and then as you place the nailer to the wood the safety will depress and it will fire once. This is usually done in one, swift action. If you do this in the opposite way by placing the tool to the wood and then pulling the trigger they often will double fire.

NR90AE Nails jammed how to remove
New user will jam the gun/ nails because gun was most likely not bump fired. Placing the gun then depressing trigger will usually cause double fire in the hands of new user. New user should practice on scrap lumber bump firing at many angles till they get the idea; or give them a training period with a nailer that has a single shot trigger (they may develop bad habits with single shot however).

I have a NR90AE . It's been used about 8 hours. It suddenly would not work at all when I pulled the trigger. The compressor seems fine. This is the first air nailer Iv'e owned and know nothing...
Over time the orings within the nailer will dry out causing problems. Adding oil thru the air inlet will not get oil to all the orings. If the gun had been in storage, add a few drops of oil into air inlet and spray silicone (or teflon) spray lube into air discharge opening at the top of the gun (it is difficult for oil to get into the head from air inlet). Before you connect the air, remove the nails and make sure that the drive piston is at top of cylinder. You can verify by inserting long metal tool (slightly larger in diameter than nail shaft) into nose of the gun and tapping firmly. This will move the piston up against the headvalve and hopefully reset it and allow oil the lube orings. If the headvalve is stuck, gun will not fire. Make sure that the safety foot is depressing the firing pin at trigger valve all the way in. Retest gun for proper action. If still no joy, remove the head and lube orings with silicone paste lube(silicone past has better sealing action but dries out over time). Good luck

I have a NR90ae(s) and when you push the gun against a board and pull the trigger there is a ten second delay before the nail is driven. What do I do?
Have you used any kind of lubricant on the nailer?
