My nail gun will not shoot nails any suggestions?

make sure nails are loaded into the gun straight and correctly

The manual for your gun specifies 34-degree nails from 2 to 3 1/2 inches long. 28-degree, wire collated nails are a Stanley-Bostitch thing and they only work in their nail guns, they will not work in your nail gun. You need 34-degree, paper-tape collated nails. I know Senco framing nails will work in your gun and I think Duo-fast makes 34-drgree nails but check that before buying them.

If you're getting an indent in the wood from the driver, the gun is working properly. If the gun isn't driving fasteners/nails it's because the nail isn't under the driver when it's activated. Several things could cause this: Having the wrong angle nails in your gun. There is something in the feed path of the nails preventing them from feeding fully into the nose piece. The feed shoe is jambed or feed shoe spring is broken.

Most nail guns are labeled with the longest nail/brad they can shoot but are capable of shooting shorter nails/brads. There should be a data sticker on the gun, usually on the magazine rail, or at least in the manual that tells you what pressure to operate the gun at, what guage brads the gun can shoot and the size of brads from shortest to longest it can handle.

check with one of your friends that have a nowinly good 18v bat if that dont work check for little pieces of plastic or pieces of the nail that are jamed up by the plunger

You broke the "hammer" you can open the housing and replace it, fairly simply. You can buy replacement parts at most large scale hardware or tool stores. The task takes about 10 min, and some simple hand tools.

I hope this doesn't offend you. What I'm suggesting is that you may not be using your nail gun correctly. Some people keep the trigger pulled and bounce the gun onto the wood. This technique works okay, but placement accuracy of the nail suffers. The other technique is to place the gun on the wood and pull the trigger USING TWO HANDS! This is the technique suggested by the manufacturer. The problem with this technique is that if you apply insufficient pressure to the gun (USING ONE HAND) the safety is not engage so you don't shoot a nail. What usually happens - I just witnessed this a couple of weeks ago - is that not enough pressure is applied while pulling the trigger so you push harder and end up bumping the gun which shoots a nail - because you have the trigger pulled, but the nail shot was a surprise so it causes another bump (and is more apt to bounce because you're using just one hand). Because it is a machine and can operate faster than your reflexes - it shoots another nail. This happens before you can lift it off of the wood, or remove your finger from the trigger. That's the reason I keep the trigger pulled and bounce it. I know that after the bounce I've set a nail, and can remove my finger from the trigger. When I need to accurately set a nail I always use two hands, press hard and pull the trigger, and release quickly. Only pull the trigger when you know you're about to set a nail, and are poised above the workpiece.

Could be couple problems. Are you using the right nails for this tool the right guage and degree? Is the nose worn allowing 2 nails to be able to shoot. Give me the model number and brand and I will try and find a print for this tool with firther suggestions, but these would be the most common

I had the same problem with my Stanley stape gun. Had to replace all the seals and piston. Works find now! Check-out internet ...search for a rebuild kit for your model of gun. Get the complete rebuilding kit ....take about 1/2 hour to rebuild.

The dial on the top of the gun is most likely the depth adjustment for the nails, this should solve the driver damaging the work piece. Make sure the nails are the correct guage for the nailer you have.
