Double fire is usually caused by trying to use a bump fire trigger system as single fire (place on work then pull trigger). If however the gun double fires when bump firing, replace the trigger valve. Some nailers have the ability to select bump or single fire. The selector for bump or single fire is usually on the trigger or just above or below the safety actuator. Other brands offer different triggers available as a part number.
When trying to determine what nail to use, look for the model number of the nailer. Letters associated with the model number will give you a clue. Example; the letters RN in the model number indicates Round head Nail. The angle of the nail is easy to determine. Just measure the angle formed by the path of the driver and any straight line of the rails.

My nailer will drive 1 nail then the hammer slides over the top of the next nail bending it and jamming the gun. It was working then this started.

There are many brands of nails that fit into the rail however the angle or gauge my be a little off thus causing miss or jam. One method to check for good angle is to place the strip of nails on the outside of the rails aligned with the top. The first nail should align with the path of the driver. If off alignment do not use them. With pinners or staplers the gauge is important. Remove one pin or staple from the strip and make sure it fits snuggly thru bottom exit. Too tight or too loose will jam. Good luck

Driver slides over the top of the nail bending it and jamming it. It will drive the 1st nail then jams.

Most jamming is caused by either wrong type of nail in gun or the driver blade tip is no longer square. Easy to check both. With nails removed strike nose of gun down against rubber mat or soft wood to move driver down for examination. It should look square. If edges look rounded or chipped, remove driver and use grinder to adjust. To check nails for good fit, lay a strip of nails on the magazine. Align the first nail with the center line of the path of the driver. The rest of the strip of nails should align with the angle of the rails on the magazine + or - 5 degrees ok but any more difference will cause jam. Good luck

Why is my DeWalt D51275 15 gauge angled finish nailer bending nails and jamming?

A few things to check - some may seem overly obvious but humor me:
1) Check your nails - make sure they are the correct angle and gauge
2) Check to make sure there is not a piece of a broken nail in the nose
3) Check the driver blade & insure it is not bent or chipped
4) Make sure the nail carrier spring is pushing nails forward and isn't getting hung up

Pin won't retrack

first thing to check is that a nail isn't jamming the pin. If not one of the seals is probably cracked
Make sure you use the correct angled nails, the wrong angle will jam in just a few shots

The gun will fire the first time but will jam when i try to fire it again.

Assuming that the gun will not jam with nails removed and the driver returns to top of cylinder when fired without nails. If the driver is bent the nailer will jam without nails. Jamming is usualy caused by bent driver, driver tip worn (not square), or wrong nails. If the driver is not bent and the tip is square, suspect wrong nails. Easy test. Place a strip of nails on outside of rails with the nail heads aligned with top of rail. Move the strip of nails toward the nose if gun. With the heads aligned with the top of the rail, the first nail should align with the path of the driver. If the first nail does not align with the path of the driver and the head is angled slightly away from the path of the driver, the driver may strike the shaft of the first nail pushing the nails back into the rails. If the head of the first nail is forward with the nail shaft angled back away, the nail will flip causing jam. The first nail should align with the path of the driver to prevent jam. It is difficult to find perfectly made nails that align correctly. But certainly check the nails with test mentioned above with every new box for accuracy. You might find that you will need to change brands to get a good fit. Good luck.

Can the carriage on a dewalt dc618 nailgun be adjusted

The only adjustment on nail guns is for the nail drive depth, the magazine is hard mounted to the nose piece. If you are having problems with the nail clips feeding, first make sure the entire feed path is clear of any nails, parts of nails or other foreign things. Then make sure the nails you are using are fully compatable with your nailgun. Your gun needs 16 guage nails set at a 20-degree angle no shorted than 1 1/4" and no longer than 2 1/2" long. Any deviation from those requirements will only give you a headache worse than what you have now.

My clipped head nailer does not shoot the new round head nails very well. constant jamming or shooting two nails at once. These are the nails stocked by Home Depot and most lumber yards

This response does not speak directly about your model of nailer, however addresses the problem of the nail supply. Generic nail suppliers are trying to sell us nails that are not exactly a perfect fit for our nailers. Nail guns are made for an exact angle and head of nail. Yet printed on the box of some of the case of nails, I see that the nails contained within will fit a variety of nailers with a variety of angles (+/- several degrees ).
You can choose a good fitting nail by taking a close look at your gun. Take a strip of nails and place them on the outside of the rails/magazine with the first nail perfectly aligned with the path of driver. With the first nail aligned with driver path, the angle of the rest of the strip of nails should align with the rails. If the angle is off slightly could be ok. Now align the strip of nails perfectly with the rails. Notice if the point of the nail or the head reaches the path of the driver blade first.
Recall that the nail should align perfectly with the path of the driver so that the driver blade will hit squarely on the head of the first nail over the shaft of the nail. If the head of the nails is forced away from the centerline of the path of the driver one way or the other, you will not get a solid square hit driving the nail true (think of hitting a nail with a large hand held hammer with an angular blow bending the nail). If the nail head is angled too far towards the path of the driver, the driver can hit two nails (the driver will hit the edge of the second nail of the strip).
The driver is designed so that it will not touch the second nail on the strip (assuming the nails fit perfectly). The driver blade is tapered at the bottom on the side that faces the nails. This taper allows the driver to hit the first nails then gently nudge the rest of the nails back into the rails slightly. To verify the shape of the driver blade, dry fire your gun into soft wood and examine the imprint. The imprint will not be round, but "D" shaped or flat on both sides like some Paslode framers. The flat side of the "D" will face towards the rails.
By using the information here, choose the nails that best fit (align) your gun (measure the angle with a protractor) . The lumber yards do not have a very good selection of brands. Try a professional fastener store that deals in nails and nail gun repair. Good luck

DeWalt d51822 framing nailer, shoots 2 nails at once 1 in 5 times

I worked at at tool rental center while attending college and learned from the old tool masters about nails and nailers. Rental stores have many different brands of nailers to rent and customers would bring their own nails of all brands. You will notice on the case/box that your nails will /should work on many other brands however the degree or angle of the nails is not always exacly as stated on the box. You should check with protractor the exact angle of your nails and also check the exact angle of the nailer. Use straight edge on travel path of the piston and another on guide rails to check angle of the gun. You will discover that all is not as stated as in a perfect world. If the angle is off slightly, the head of the second nail will get into the path of the driver. This happens mostly with clip head because the nail heads are so close together. The full round head is spaced further apart with less jamming. If angle is off slightly, take a look at other brands of nails with protractor in hand, the angle will be different slightly or choose a slightly thicker nail. Look for the nails to fit with bottom of nail hitting the barrel first. This will move the head of the nail slightly away from the center line. Finally do not release pusher with force as this will jamb nails closer together. Good Luck!?
