Many causes for this problem. Some things to check. Push the driver up by hand to see if it moves easily /hard. If hard, check for bent driver or dry cylinder. If it moves easily, check piston oring too worn and /or air could be leaking down past the bumper area. Most guns have very close fitting bumper or a seal below bumper. If too much air leaks down past bumper driver will not return fully. Check seal could be loose or broken. Remove cylinder and look for check seal covering a row of holes on outer/mid to lower part of cylinder. could be a band or oring and should fit rather tight. If ok only other parts to check are the headvalve and piston stop. Piston stop should not have cracks or missing pieces (piston stop slows/stops piston when it returns to top). Head valve should be well lubed. Good luck

    there are all new seals and a new driver installed in it, tought that would fix it but it didn't.

    Lots of new parts in gun then, good. Try some tests. Assuming no leaks. There needs to be air pressure under the driver piston to push driver up. Check valve that sets on a row of holes on outside of cylinder must be very snug. Some brands use a band others use orings. I have found that on many guns too much air leaks down the nose and cant push up the driver. Some brand of nailers use a washer below the bumper that fits snuggly on the driver, however on guns that do not I cut a thin piece of rubber (like tire tube) that fits nicely below bumper and make small hole for driver to fit thru. The goal is to create a nice seal at bottom of gun. Now test, if works ok your done. If no joy, problem is in valve head/piston stop. First remove head, to test seals. Push down valvehead and cover small hole on gasket surface with finger. If seals are good the valve will stay down under vacuum and come up when you release hole. If test ok then remove valve (plastic or metal piston that has orings) and pull piston stop and spring. Piston stop must not have missing pieces or cracks. Reinsert piston stop into valve and check for nice fit. Stop should fit into valve snuggly and stay put. It should not take much pressure to snap into seat. If it fits too tightly into seat/ then hard to remove from seat then problem, you could sand outer surface or replace (as driver is being pushed up to top the air above the driver must be expelled easily thru the valve head/piston stop/top of head; If too much resistance piston will not reach top ). Good luck and let me know your progress.

    When you insert piston stop into valve for test fit put it in without the spring, you are only testing the fit of the stop into valve. (when all parts are assembled and the gun cycles the piston stop overcomes the power of the spring and makes contact with the seat) One more test after you reassemble. Connect air to gun and dry fire gun into rubber mat or soft wood but continue to hold the gun against wood/rubber and continue to hold trigger. Driver will stay down under pressure, during this test no pressure should leak out of nose or head., if leak out nose, lower bumper is problem, if leak out head piston stop is problem.

My RN175 shoots you think it shot the nail, but when you move the gun to shoot the next nail the nail you just shot falls out the end of the gun. What could cause this?

The driver is coming down far enough to break the nail off the strip but not far enough to drive it in. This could be caused by any of the following:
- The driver is broken off and too short to drive the nail
- The driver is bent and doesn't travel all the way down
- The seal/o-ring on the piston is damaged and air is leaking past it
Any of the above will require you to remove the head and inspect the driver, piston and o-rings or have a service center check it out.

Nail gun will not fire the nail. Compressor works fine. Hammer doesn't retract enough to hit nail? Cause, solution?

could be a jammed nail in the magazine nose area, bent driver blade or problem with the o ring being worn.

Driver pin on model FN250A not retracting far enough to drive next nail. Will shoot 2 or 3 nails and miss 6 or so.

I had the same problem with an electric stapler from Craftsman after years of disuse. The solenoid that powers the hammer that is no retracting may require lubing if this is possible.

If not, then if the product is within warranty, you might be able to get a replacement.

MY 18GA nailer will fire but it wont fire the nail.

Usual causes:

Driver doesn't move back far enough. Usual cause of this is inadequate lubrication. Load a bunch of air tool oil, say 20 drops and cycle unit repeatedly.

Wrong type nails.

Nails not properly seated in the tray. Check that they can move freely into the slot/path the driver comes down.

Jammed or broken nail in the path. Disassemble and clean out debris.

Broken nail parts up in the area below the piston. Disassemble and clean out debris

you have lost compression on your piston o ring, instead of air pushing the piston back for the next nail its going around the piston , and the proof is that your piston will move with a simple tap. please replace all orings, because if one is worn the others arent far behind, if you dont replace all , at least replace the piston one and all the cylinder ones,,o rings kit are available at your nearest nail store or try plz rate this answer,,tks

Paslode impulse cordless nail gun,doesn't pull the piston back far enough to catch the next nail, so when I fire it no nail is picked up by the firing pin. batteries are good(new), cylinder is new, any...

This is an easy fix luckily usually it means that the chamber is dirty and all you have to do is open the top front of the gun so that you can see the piston then take a q-tip and clean the area really well sometimes it requires a degreaser and then when you think that you have it clean make sure to lubricate the chamber really well with the paslode lubricant that came with the gun or they sell it right next to where you get the nails. Then the gun should work fine with no problem if this does not work then this means that the piston might be bent and that could turn into a big problem but is still fixable just harder.

Hope that this works for you

Nailer piston won't retract far enough

the rubber cap just pulls off. maybe a screw driver to pry it first but it does just pop off.

As for oil, Always use what the manufacture recommends. But in the case you can figure that out, use a low viscos oil, maybe a standard 3-1 will do in most cases.

Also WD-40 works well.
