MY NAILGUN QUIT FIRING NAILS. I LOADED UP TWICE AND USED NAILS BUT AFTER LOADING THE 3RD SET OF NAILS MY NAILGUN WON'T FIRE THEM INTO WOOD. WHAT I HEAR IS JUST A SMALL AMOUNT OF AIR FROM AROUND THE TRIGGER.

Hi Charles & Floyd:
Just a couple of thoughts that may assist.
First. This is an air tool so it is DANGEROUS! Treat it like a LOADED GUN.
Here's what I would do:
- Disconnect from air supply - point away from anything I don't want to hurt, and squeeze trigger. Press safety against block of wood and squeeze trigger.
- Now that I know it is safe, I would remove the nails from the magazine and check that none is stuck in breech mechanism.
- Check that feed spring/latch has released. Sometimes if loaded too full it can catch.
- Load some nails, check that they are the correct fit, and are sliding in the magazine.
- check air supply pressure. Should be between 80 and 100 psi.
- reconnect air supply and try again.
- If it does not fire it may be that the piston is not fully retracting. Since it is new, I would be returning it to the store where it was purchased.
Hope this helps.

put a smal amount of machiner oil in the air inlet fitting as the unit needs lubrication of then piston

If the trigger is set to single fire, you will need to place the gun against the work then pull trigger as you have done. Try setting the trigger to bump fire and try again. If hear a thump inside the gun, remove the head and check that the head valve in not stuck from lack of lubrication. Easy test, remove the nails, remove trigger pin, remove trigger and manually push trigger firing valve. If the gun fires then suspect faulty trigger or safety arm not lifting enought to activate the trigger valve. Good luck

Best practice is to bump fire the gun to prevent double fire. Do not place the gun on the work and pull the trigger. This takes practice while using at an angle. Works better if the nose piece has rather sharp points to help nose to stay in postion while you bump. With trigger depressed, practice without nails bumping/hitting wood at different angles untill you can bump hit at the spot that you need the fastener. If the gun double fires while bump-firing, most likely all the safety/trip parts are worn/loose. Not expensive to replace. Good luck.

Usually safety foot is not making full contact to trigger mech. First test trigger valve. Remove nails, remove the trigger to expose the trigger firing pin. Connect air and test fire by pushing in the firing pin with your finger (dry fire onto wood or old coiled rubber hose, use very quick pushing action against trigger pin). If the gun works, replace parts and adjust the safety foot so that the lever below the trigger is pushed all the way up and lever depresses the trigger pin all the way in. Good luck

Nail jamming is caused when the driver is able to hit two nails with one stroke. This usually happens on nailers that use nail strips with no spacing between nails. If the driver is damaged, it may be able to hit part of the second nail. If the wrong nail is used and two nail heads are in the path of the driver then jam. On nailers using nailstrip with space between nails, it is much harder for driver to hit two nails. Most jamming, however is caused by the nailer actually firing twice in very rapid succession. this type of jam is caused by faulty firing mech. (safety foot or bump fire system) , faulty/worn trigger valve or worn orings in the headvalve .

Nail guns either have a switch or a seperate trigger assembly for two options - automatic, or 'bump' fire, and sequential fire. Sequential firing may be best for you since the nose must be fully depressed and the trigger pulled for each nail.

If you're stuck with bump firing, practice your technique. Double fires often occur when the workpiece bounces back into the nose of the gun; learn to 'bounce' the gun off the material to avoid this second contact.

If you're getting double fires in sequential mode, the problem could be more serious. I keep a can of aerosol silicone lubricant on hand to clean and lubricate the feed mechanism and magazine. Make sure your tool is clean and lubricated before each use, including the 3-5 drops on the air coupling.

Check that your air pressure is not set too high. Overdriving nails reduces their effectiveness and can cause tool malfunction.

This problem could also be caused by worn out O-rings or other parts within the tool. If you're not comfortable servicing the tool yourself, take it in for repair/maintenance work.

Another important thing to remember: With tools like this, you get what you pay for. A cheap nailgun will never function as well as a quality nailgun.

dewalt nailgun jamming "constantly"

its double firing, after firing gun pull back, what is happening is when you fire a nail your pushing the gun back onto the wood and its putting another nail in

Yes,this is a common "mis fire" by Pasilode. I own the 16p Framer and the Angle nailer and I never get it from the Framer but I do get it seldom from Trim Gun,nothing you can do ,its just a misfire.
