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

I just received a reconditioned DeWalt D51822 framing nailer and i bought 3" nails 2 3/8" galvy nails. The 3" work fine, the 2 3/8" shoots out 2 nails at once every 4th or 5th time i pull the trigger. The nail manufacturer is POSI - SET which i bought not at a discount retail store, but at a bona fide contractors supply store.

Are there certain manufacture's nails that work better than others or should all the 31 to 34 degree, clipped head, paper sheathed nail work?

    The 2 3/8" nail diameter is .113" which is in accordance with the DeWalt manual. The 3" nails are longer with a slightly bigger head and have a slightly bigger diameter of .120" also in accordance with the manual.

    I had heard from a friend, that he believes that some nail guns just work better with certain manufacturer's nails, but i can't confirm that information on the web.

    I am hoping someone at Fixya can help :)

    Are the shorter 2-3/8" nails the same diameter as the 3" nails?

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!?

D51822 is nailing at a 45 degree angle instead of 90 degree

hey not sure what the d51822 brand name is I work on bostitch as a service tech. so well the obvious question with the details you've given 45 degree angle? so are they bent over to get that angle? not sure how they can come out straight and get bent. ok the nose ( where the nail comes out) is it completely flat on the board? if so I would be nearly impossible to create a 45 angle. not doubting you. I work on F28WW bostitch thinking they are similar so, check the bolts on the top (loose or damaged) or the nose its self see if it is bent. it would be only slight because otherwise the driver ( what pushes the nail in) would get jammed and not fire at all .try that first thinking the nose is bent and if its bent its junk. because cracks are next and that's when really bad things happen fast.

Air comes out the nose of my dewalt framing nailer

Again sounds like blown O ring give it a squirt of 3in1 oil and fire it several times (if oil is compatible in your gun). Repair center if that doesn't work. Trash can also get in the air orifice and stop moving parts from moving.

Common problems dewalt clipped head framing nailer

there is NO easy solution for this, but unplug air and get a pair of safety glasses and a punch and try and knock the driver up into the tool away from the nail or if it is just jammed try and pull the nail out. You didn't really specify where the problem is. Let me know if you need more assistance.

I have a d51822 framing nailer that will shoot a nail but then not recoil to shoot the next nail, if you wait 10-20 seconds the gun will release air at the top of the gun and recoil

Most likely there is a problem with swollen orings between the cylinder and cylinder spacer (white plastic piece between cylinder and body ). Order the oring kit because nost likely when you take the gun apart the orings will fall apart. Dewalt used vinyl orings instead of viton on critical areas of the cylinder and these vinyl orings failed.

After shooting a nail, it fires out two more nails.

Dewalt has a new trigger valve to replace the original (part number 5140095-73). Not sure if the new valve is replacement to address an issue or natural progression. I would also replace the orings that make contact with the reference #55 on parts list called the bulkhead. There are four orings contacting the bulkhead that wear and may contribute to multi-fire. Parts are at dewalt service center or at Good luck
