D51844 Framing Nailer won't fire

Ran a few trial nails on this reconditioned unit. Went in okay, but I unloaded, disconnected, and increased depth.

Now, when I try to fire, I feel air release at trigger (on my fingers) when I depress the trigger. I'm dead in the water. Running about 100psi.

What am I doing wrong, or did this unit fail in the first ten minutes?

Adjusting the depth of the nail also changes the amount of pressure that is applied to the trigger pin. This is not actually a problem with the adjustment, however indicates that the orings in the gun are not completely sealing or is lacking lubricant. Adjust depth so that maximum pressure is asserted against the trigger pin. The trigger pin must be pushed all the way in very quickly to fire the gun. Test by removing the trigger and depressing the trigger pin by hand all the way in quickly. Enjoy

How do I release the trigger lock on a brand new porter cable nail gun


Are you depressing the nose of the nail gun against the material to be nailed first? Without doing this, the trigger will not "unlock". You can read a pretty in-depth review of this nail gun at OnlineToolReviews com Porter Cable FR350A Full Round Head Framing... which might also help.

How do I adjust the depth of the brad nail on the porter cable BN 125A brad nailer


Hello. To adjust the depth of the nail you have to increase or decrease the air pressure from the compressor. Look at the compressor and you will see a knob or dial that you can turn to increase or decrease the air pressure. Do this adjustment in small increments testing the nailer by driving nails into a scrap of the same material you will be driving the nails into on the actual job. Increasing the pressure will drive the nail deeper and decreasing the pressure will drive the nail less deep. Joe

Have you checked to make sure the depth adjustment hasn't moved.

If it got banged hard enough it could have moved it and reduced the impact of the nailer

Framing nailer not setting nails


If your compressor pressure is right (im sure it is) there is a plunger located above the point where the nails come out. A moderately size tool store (not home depot) should have a rebuild kit. For me.it was where I bought my nails

For the Dewalt d51844 can you use PAPER or plastic collated nails


Yes you can generally interchange the two (paper vs plastic collated) as long as the nails meet the specifications (and collated angle) specified by your nail gun.

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
