The nails won't come out - Senco Cordless 41 15 Gauge Angled Finish Nailer

super glue then take off with acetone

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.

Open the front and see if the nails are feeding through. If the piston is down push it up, close the front and try again.

Some causes, in order of probability:
Roofing nailers get a lot of tar build up on them, especially around the nose safety and nail feed pawl area. Cleaning off this buildup will usually take care of most problems with roofing nailers.
On the side of the gun away from the side you load the nails on there is a small cylinder with a piston inside that attaches to the feeder pawl. If air isn't getting to the piston or the piston's o-ring or spring is damaged, it won't cycle properly to advance the nails.
If the driver doesn't retract fully, the next nail won't be able to advance properly for the next shot. This can be caused by o-rings in the head that are worn or out of their proper place.

Stop using it and take it in for service. If it is leaking air then an o-ring or seal may have failed (most likely guess) and it needs to be replaced.

First, check that you are using the proper nails. The FP602 needs Full Round Head nails with plastic collation. If you are using Clipped Head nails with the paper tape collation the angle of the nails not let the driver catch the next nail and drive it into your work.
If you have the correct nails, check the magazine to make sure the nails are feeding all the way up to the driver. If there is anything blocking the way or if the spring on the feeder isn't taught enough to pull the clip all the way up the driver won't be able to catch the next nail and drive it in.

Check the pin and spring on the feeder. They are known for having the rubber washer fall off then the pin falls out. Also is the spring is bad or missing it won't feed.

could be a few areas to look at. First does the driver retract fully after firing a nail, if not then I would replace the piston o ring. Do the nails move freely in the magazine, if not the magazine could be bent or possibly you have a problem with the nail collation, they have to slide freely and I think both areas need looked at. If you need more assistance I would need the brand and model number so I can help better.

check the height of the magazine, but I think that you have a problem with the feed piston or there is a spring on the feed pawl that might be broke. Unload the nails and dry fire the tool with the door open observing the piston movement. It should "SNAP" back and forth if it does unplug the air and check to see if the spring that applies pressure to the pawl is broken or missing. I am going to guess the piston. If this tool has not been serviced in a while the asphalt tends to jam up the mechanisms. Let me know if you need more assistance.

I ran into this problem many times. Don`t use the Bostitch brand nails. Use the generic or other name brand. You`ll notice the generic one`s heads are just a little bigger and the driver blade won`t run down the side of the nail!
