Shooting but not nailing...not feeding nails - Dewalt D51256K 16 gauge finish nailer kit

If the driver part of the gun works well, check the feed parts. First check the feed pawl where the nails lay. The teeth should be proud enough to catch and hold the nails firmly and it should work freely in its channel. Next you have to check the parts that drive the feed pawl in the cylinder on the side of the gun. There are seals and a spring and piston that should be checked. Replace any worn or broken parts.

If you're getting an indent in the wood from the driver, the gun is working properly. If the gun isn't driving fasteners/nails it's because the nail isn't under the driver when it's activated. Several things could cause this: Having the wrong angle nails in your gun. There is something in the feed path of the nails preventing them from feeding fully into the nose piece. The feed shoe is jambed or feed shoe spring is broken.

Usually miss feed happens when the driver does not return to top position not allowing the nails to feed into position. Easy to check, point nose of nailer up then down again to see if the driver is loose in the cylinder. If loose, the driver will be in the down position when the side door is opened. If driver is down, replace driver oring. If driver oring is good, look for spring tension on feeder and check feeder spring on the door side. If piston oring good and feeders have good spring tension, suspect lower bumper cracked(remove head and piston to check bumper).
On gun with depressor (safty foot) not actuating trigger, look for worn trigger (trigger inner lever could be worn) or loose or worn firing pin in the trigger valve above the trigger(valve # tva6). Replace as needed. To check for proper gun action, remove the nails, remove the 3mm roll pin holding trigger and dry fire the gun by depressing the tigger pin. Good luck

could be a few problems, the feed piston might be sluggish, the spring might be missing off the feed pawl, the collation of the nails or a bad coil of nails, the driver might not be retracting fully. Now for the way to check some of these. First look at the coil of nails and the adjustment on the magazine, the nails should pull freely off the coil. Next remove all the nails and using a block of wood "dry FIRE" the tool with the feed door open to check the movement of the feed piston, it should snap back and forth and if it doesn't that would probably be your problem, could be dirty/worn orings or debris in the air chamber. UNPLUG air hose and check for the finger spring that holds the feed pawl tight and check the pawls for wear and asphalt not allowing it to catch the nails. Lastly fire the tool and check the piston, did it retract fully allowing the next nail to advance? if not you would need to probably replace the o rings in this tool. Let me know if you need more assistance. And if I have helped you would you please vote accordingly, thanks

check with one of your friends that have a nowinly good 18v bat if that dont work check for little pieces of plastic or pieces of the nail that are jamed up by the plunger

the first thing that i look at when a gun is double shooting is the nails. if i have the right nails then i check the driver( part of the gun that hits the nail) if the driver is fine( not bent or broken or worn) then your nose( chamber that holds the nail right before being shot out) is worn or broken. either way to answer your question , no , double shooting is not only dangerous but a complete waste of time, ps rate , tks

You should be able to open the load cover and be able to remove the nail. Sometimes the nail wire is located in the wrong spot which will cause the feed pawls to get jammed, and also cause the nail to get hung up. After you get the nail dislodged make sure that your canister is set to the correct level for your size nails. Then lay the nails down to load it. Check the placing of the wire on the nails in relation to the feed pawl. If the wire is on the feed pawls you need to find another roll of nails and do the same thing. Sometimes the wire is misplaced during production and affects certain nailers. If you have any questions please post again.

if u are right nails for gun,then make sure when u put coil in and feed in front of firing pin the nails are straight with pin and connecting wires are not bent causing nails to fall out of alingnment.

Could be couple problems. Are you using the right nails for this tool the right guage and degree? Is the nose worn allowing 2 nails to be able to shoot. Give me the model number and brand and I will try and find a print for this tool with firther suggestions, but these would be the most common
