SOURCE: BNA125A Porter and Cable brad nailer

Both of these nailers have a check seal about half way down on the cylinder. This check seal causes the piston to retract if the piston ring is not too worn. The lower bumper should not be cracked and missing pieces, and the driver guide washer must be in place below the bumper. Also check that the driver is not bent causing it to get stuck. The da250b has an upper bumper of sorts and developes cracks that can only be seen by removing and inspecting, If cracked, the upper bumper must be replaced for proper function. The bn125a nailer probably has the discharge port clogged or upper valve parts worn or cracked. The headvalve should be inspected for cracks where the oring fits and the rubber seal should fit snug on the valve. There is a spring that pushes down in the headvalve that pushes from a rubber washer of sorts, check the diagram to be shure that all parts are in order. Both of these guns will not take too much pressure. Try adjusting to about 90 lbs max.

SOURCE: Stanley Framing Nailer Leaking Air Around Trigger

Your tva11 valve can be repaired easily if you have a source for orings. I purchase orings from several companies including lowes (in plumbing dept sold in 10 pack for about dollar), www.grainger.com (oring kit metric, cost about $10) harbor freight (oring kit about $5), also orings are sold by size at bearing companies. I have repaired many of these valves by just cleaning debris and lubing with silicone paste (sold at lowes in plumbing dept used for lubing faucet orings). To attempt repair of valve, remove nails, remove roll pin that holds trigger (3mm) to expose tva11 valve. Mark position of valve in body of gun because the retaining pins fit thru an indention in the valve. Next remove roll pin/s that hold tva11 valve, they are just above the valve in the body of the gun(3mm x 30mm). You will need to apply air pressure to gun to remove the valve, however use heavy glove to catch valve because it can come out with force. (try lowering air pressure to gun for this procedure. With valve in hand, use marker to mark position of inner part in relation to outer, remove the two pins that hold valve together. Push out the inner cylinder and look at the middle oring(usually the problem, could be loose or cut) , If cut or loose replace and lube with silicone paste and re-assemble. Check outer orings for nicks, replace as necessary (usually good). Clean valve port, lube port, then re-install valve into gun and insert temporary retaining pin and test for leak. You should be good to go. Good luck and email if you have questions.

SOURCE: porter cable brad nailer only fires brad on second trigger pull

The dent in the wood is not caused by the air. It's caused by the set that drives the brad. Are you oiling it consistenly? Are the brads the right manufacturer for your porter cable brad nailer? From the information you give it appears that the brads are not advancing correctly or that the air pressure is not sufficient to dislodge the brad from the brad strip on the first strike - it takes an additional strike to break it free. The standard for adding oil is to add ten drops of air tool oil for every hour of operation. That seems like a lot, but the correct amount of oil is a sure way to prevent most air tool problems.

Testimonial: "Thanks for the info. I was not oiling it at that rate. Is there anything I can do to fix the issue now that I didn't prevent it?"

SOURCE: I have a N60FN Bostitch nailer. It's loosing air

Your nailer uses a trigger valve part # tva6 (or tva1, but use tva6) (cost about $20) and is sold at www.bostitch.com or ebay for generic. If you have a source for orings, you could try to repair the valve. Remove the roll pin that holds the trigger to expose the tva6 valve. There are roll pin/pins that hold the valve in just above the valve in the body (Use punch for 3mm hole). Remove these pins and apply air pressure to gun to pop-out the valve. Use caution when you do this. Remove nails, lower pressure to gun and use glove or rag to catch valve because it could come out with force. Note the two grooves on the side of the valve where retainer roll pins hold valve. Remember to insert the valve with these two groves aligned with path of roll pins. With tva6 valve in hand remove two pins that hold valve together and remove inner plunger. The middle oring/seal on plunger is cause of leak. Try using an oring with smaller inside diameter than the broken or loose fintting seal that is present. It must fit pretty tight and be slightly thicker than 1/16" to work. Remove the outer orings to valve and clean and re-use same. Clean the valve port in body of gun and check for sharp edges to prevent cutting orings before inserting the valve. Use silicone lube or oring lube on the orings and the valve port (Danco silicone paste sold at Lowes in the plumbing department). Good Luck on your repair and email if you have other questions

I have already changed trigger valve assembly, O rings and all. Still leaks when I try to fire. Will not shoot brads just leaks lots of air around trigger assembly.


Most likely problem is the head valve orings not making perfect seal. Remove the head and pull out the headvalve piston. Apply plenty of white grease to orings and test fire. If gun fires, will need oring kit soon. Good luck

Air leaking from trigger Bostitch SB1850BN


Most likely the orings or seals in the headvalve are not making perfect seal. Remove the head and pull out the headvalve. Apply plenty of white grease to orings and test again. If the gun fires, then will need oring kit soon, or just keep using plenty of grease. If the gun still does not fire, check that the safety foot is depressing the trigger valve all the way in. Good luck

My brad nailer will shoot one brad then nothing until I take out and reinsert the brad, then one shot, etc.


Hi Robert:
These tend to be very reliable tools but they do have some quirks.
1) They need to be oiled regularly so if you don't have an automatic oiler, a couple of drops in the air inlet before you connect the first time every day will save you grief.
2) The brads are fed by spring pressure, and the magazine and spring assembly have to be kept relatively clean. Use air to do a decent job. (WEAR SAFETY GOGGLES)
3) The firing mechanism likes a decent amount of pressure, not enough and mis-fires are common. DO NOT EXCEED MAXIMUM ALLOWED.
4) The hammer assembly and slot MUST be clean and not binding. Use the allen wrench that came with the gun and dismantle, clean, and re-assemble making sure that there are no rough bits that are creating the problem.

DISCONNECT FROM THE AIR SUPPLY BEFORE YOU START THIS MAINTENANCE

CHEERS!!!!

When you pull the trigger air comes out near the trigger and no nail is fired.


The problem that you describe indicates that the orings within the trigger failed. You could replace the orings if you have a source for very small rings (2mm x 1.5 for the firing pin inside the trigger valve) or just replace the whole trigger assembly (under $10). Lube all orings with white grease or silicone paste lube (remove head and lube head valve assembly). Good luck

Air is leaking from somewhere around the trigger and the nailer will not fire...the gun is only about 3 months old


I would take it back for warranty repair if it is that new. If not I have detailed instructions on how to remove the trigger valve assembly from the tool. If it is leaking air it is probably a split o ring on the valve.

Bostitch N60 finish gun - air leaks out of the trigger when the air hose is connected


There is an oring that is probably broke in half, It is referred to as a purple o ring. You can buy the whole trigger assembly but I think that just replacing the one will get you going. Let me know and I will try and help more

No brad


Your anvil is not returning to the home position to allow the brad to index into the receiver. Try and push the anvil up all the way to the home position. If that works, then you need lubrication, new return spring, etc. All related to the anvil firing.

The driver assembly can sometimes get bent or the tip can get a little deformed causing it to hang up in the nose. Other than that, not much else it could be if you rebuilt the whole thing
