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

HELLO I HAVE THE HILTI TE76-ATC WITH CODE 330200 WE CHANGED CARBONS . HOW I CAN MAKE THE RED LIGHT FROM ON TO OFF.


Are you mechanically inclined??? This is a little involved to do. First UNPLUG tool and remove the back section/trigger, there are about 6 screws holding the assembly to the back of the tool. REMOVE as an assembly. SQUEEZE trigger and PLUG into electrical outlet, while holding trigger unplug and reassemble, try this if light still on plug assembly in squeeze trigger and while holding the trigger unplug and retry. One if these should take care of resetting the light. If not the only other way is to send it to HILTI and have them reset it. Let me know if you still need more assistance and results.

All the sudden the nail gun stop working, pull the trigger air leaks out at trigger area


I had a similar problem with one of my nail guns. What I found was a small rubber o-ring in the trigger mechanism had split. Once I replaced this the problem was corrected and the unit functioned fine.

You could replace the whole trigger assembly for about $35. But if you remove the assemble and replace the split-ring this would only cost a couple of bucks at most.

Trigger assembly shown below. ereplacementparts.com is one possible source for the trigger assembly others can be found on the Internet.

The safety foot assembly pushes up on inner trigger lever which in turn pushes on the trigger valve. If the trigger valve firing pin is slightly shorter than the old trigger valve, or the inner lever is worn from use, the inner lever will not push the trigger pin all the way in. Examine the trigger and the roll pin that holds the trigger for wear and check that the safety is pushing up on the inner lever. If the trigger is worn replace or repair with metal type epoxy filling in worn spots and use a new roll pin.

I have a 28 deg Bostich framing nail gun that is leaking air around the trigger. Not sure which seal, but need help in dismantling it to check which o-ring is broken.


you need a trigger assembly it sounds like/ to remove you will find 3 roll pins, unplug the air supply and remove all the roll pins in the trigger/switch and then the trigger valve ssembly is easily removed BUT follow closely, after removing the roll pins remove the trigger and then holding a rag under the trigger assembly pull back on the collar to release the bit. clean with chemicals and try ing to find that special commodity.

See the link below for a parts breakdown of the gun. Usually this problem is a defective trigger assembly and requires that the trigger be replaced. You can also check the Orings. If there is an air leak this can also occur.

I need help replacing a bostitch framing air nailer trigger model 28ww it's leaking air and won't work.


follow closely, do you have a new trigger assembly because the problem is with one o ring commonly referred as the purple o ring in the kits? either way the procedure to remove the trigger is first knock out the roll pin for the trigger latch and then the 2 roll pins for the trigger assembly. next get a shop rag or equivelant and place under the now exposed trigger assembly and then while holding the collar on the air chuck plug into tool and hold rag tight and trigger will "pop" out pull the chuck away and remove the 2 pins to disassemble the assembly or install in reverse order lubricating the o rings first. Let me know if you have any questions or problems.

Myn60fn is leaking from around the trigger, do I have to take the whole thing apart to replace the o rings or do I just drive out the spring clips?


You will need to remove the trigger before driving out the roll pin. After you remove the trigger and roll pin, place a rag over the trigger, remove your hand from the area, and briefly hook up your air line. (Clean your soiled pants after this part) You will hear a loud pop and the trigger assembly is going to come out quickly. If you are not prepared for this it will scare the **** out of you. Then once you have the trigger assembly out you can push the two retaining pins on the assembly out and remove the inner workings of the trigger. One note of caution. The ring you are trying to replace is a hard half moon looking ring that Bostitch doesn''t sell separately. You may see it in pieces when you take this assembly apart, or you may not. Sometimes it crumbles and comes out of the trigger exhaust. You can try to match up an oring to sit in there, but from experience it is much easier and less costly to just order the whole trigger valve. Hope this helps.
