SOURCE: D51844 Won't Fire Nails

The Dewalt D51844 uses a full round head 20 degree nail. Sometimes the generic brand nails are not made exactly to the stated degree. They do this so their nails will work on a variety of nailers. Best to check the nails angle in relation to the angle of your nailer. Place a strip of nails on the outside of the rail. Align the heads of the nails to a convenient straight edge on the rail then check that the head and shaft of the first nail is aligned with the barrel. If the lower part of the nail projects out further than the head, then the driver will miss the head. If the head of the first nail appears close enough to barrell for the driver to hit it then place a new strip of nails into the mag and slide the pusher foward. Fire one nail, if success, remove the nails from the mag and check if the plastic holding the nails together is projecting in front of the first nail. Sometimes the plastic is not right, too stiff, and will not let the next nail align with the barrell. If the next nail appears ready and slides forward then the driver may not be going all the way up after shot. Check by inserting a metal rod into barrell and push driver up till it stops. If the driver is in the uppermost position, then most likely brand of nails. Use Dewalt nail. Good Luck

SOURCE: framing nailer, dewalt d51823 doesn't fire.

Generally, when you attempt to fire and only get an air sound at the trigger, the problem is air leaking past the orings in the head valve. Here are a few things to check and a simple test.
Remove the trigger from the gun so that you can have access to the trigger pin. Remove the nails from the gun. After removing the trigger and the nails, reconnect the air supply (check for 100psi) Place the nose of the gun against wood and with a very quick ****, depress the trigger pin all the way in. If the gun fires then the safety foot is not allowing the trigger to depress the pin all the way in. Make adjustments to safety and check for worn trigger and trigger retainer pin. If the gun does not fire, remove the head. Place the head on table and depress the headvalve all the way in with your thumbs then place a finger over the small vent-hole on the gasket surface and release thumb pressure. The headvalve should remain depressed due to vacuum in the valve and will pop up when you remove your finger on vent hole. If the headvalve does not stay in, air is leaking past the orings. Remove headvalve parts and use magnify lens to find small scratches on the surface where orings contact. Remove scratches with very fine sandpaper (300 - 400 grit) Make sure all the orings are not cut (use magnify lens) and fit snuggly. Lube with "Danco silicone grease" available at lowes in the plumbing department. It is used to lubricate orings in faucets. After re-assembly, do vacuum test as described above. If you have vacuum, head is ok. Make sure that the gasket seals around the vent hole where the head mates against the body. You should be good to go. Good Luck and email if you have other questions.

SOURCE: Dewalt D51822 fires once only

Hi Bud, This is a common problem as they get older. The mechanisms get a little worn and they pick up a lot of debris, especially the stick nailers. I have had an old bostitch for over 20 years and instead of rebuilding it all the time, I have taken to cleaning it regularly and taking it apart once in a while and wiping it with steel wool to check for any burrs and tiny pieces of the stick wire. The best results I have found are to wash it down with an engine degreaser and blow it out throughly with compressed air and then relube with pnuematic tool oil, especially the piston. Also be sure to put a few drops in the air inlet each time you connect it so it lubes the piston from the inside. Take out any nails and fire it several times onto a piece of wood to make sure the lube reaches everywhere. If you get a little too much inside it will spit it out as you nail but for framing that is not a big deal and I would rather have a little more than not enough. Good Luck, this should Fixya!

SOURCE: paslode pneumatic nailer will not fire

Check gas expiry date, failing that reove four bolts from back and two from front nose and remove cylinder housing, check piston is free in cylinder and driver is right back, to check you have spark with battery in push and hold down switch arm just below fan and pull trigger you should see and hear the spark, if there is spark you may just need to clean arond spark plug to get a more positive spark, also check o-ring on fan housing as if this is damaged it will alow gas to escape and no ignite.

SOURCE: dewalt dc618 nailer is not firing

I have both the DC616 and 618 and have used them sucessfully for about three years. Two main things go wrong. There is a drive belt that breaks (drives the spool that give the energy to drive in the nails), second are two small rubber bands on either side of the drive head that break. The bands can be accessed by taking off the front silver cover, the drive belt is access by spliting the case. Make sure you are using the correct nails or the drive pin may become bent and will jamb repeatedly. Hope that helps!

My cordless Dewalt finishing gun has stopped firing when you try to fire it in a vertical position. Works fine on skirting and architrave but just gives a little 'pop' if try to fix anything to ceiling.


is this a gas cartridge type of nailer? It could be the effects of gravity on the spray nozzle. try pushing down in normal position but dont fire it. quickly move to ceiling then try firing. I am not a fan of this type of nailer as they are problematic and finicky.

Dewalt D51238 not firing when trigger pulled but air does come out?


Remove the head and lube the headvalve with white grease. If gun still does not fire and makes air noise at the trigger valve then orings within the trigger valve are worn. Replace the trigger valve or if you have a source for small orings, just replace the two orings on the metal stem (2mm x 1.5mm). Dewalt uses vinyl orings on the stem that fail. Replace with buna. Good luck

Nailer will get two nails jammfrontiered at same time about every 3rd nail


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 .

I have a DC608 cordless nailer that will not fire the driver the driver does not move at all but everything else seems to be functioning properly Thanks Tim


Hi,

You can go to this webpage and download the owner's manual which gives instructions: http://servicenet.dewalt.com/Products/Detail?productNumber=DC608K
You can also download a parts diagram and order parts here.

I looked through the manual and found that DeWalt's Brad Nailer does not require tools to remove jammed nails from the nose piece. I believe this is the problem with your nailer, unless it's empty. Some of these nailers will not fire if there's less than 6 nails in them.
Another feature on this nailer is the trip lock. It is a safety feature that prevents accidental firing. Any time you adjustments made to the nailer will automatically turn the trip lock to lock position. You'll find this lock on the right side, under the Dewalt label.

The instruction manual will explain all this.

Hope this helps. If it does, I would appreciate a vote. Thanks,

Handie Andie

Press the trigger and all we get is a puff of air


could be driver stuck with jammed nail or the firing valve is stuck in the head. If this is a Dewalt tool go to Dewaltservicenet.com and type in your model number for a breakdown before removing the cap.

Nailer jams with 1-5/8 brads


It sound to me that the 1 5/8 brads are not 18 guage but probably 16 guage and they will not work. Double check them first before going any further. You can usually lay them next to the smaller ones that work and see the size difference, if not let me know and I will dig deeper.
