SOURCE: BOSTITCH 2IN1 VENTS AIR AND WILL NOT FIRE

Your nailer is one of many bostitch nailers that use the TVA6 trigger valve. With time, this triggering valve will wear and act as you describe. Some TVA6 valves have a green plastic pin that wears and becomes shorter. (some have a metal pin) The safety foot and trigger can also cause problems. Try the following to determine the problem:
Remove the roll pin that holds the trigger in place to expose the tva6 valve pin. Remove the nails from the gun and connect airline. Place the nose of the gun against wood or hard rubber and with a very quick motion depress the trigger pin all the way in. If the gun fires then the problem is that the safety and the trigger are not depressing the tva6 pin all the way in. Check for worn parts and replace as necessary.
If gun does not fire remove the head from the gun and check headvalve for worn orings or very tiny scratches where orings contact surfaces. Use a magnify lense to check surfaces if necessary. Use very fine sandpaper to remove scratches (300 grit). Lube orings with silicone paste (looks like vaseline, sold at Lowes in plumbing department it is used to lube faucet orings) and re-assemble. This will make your nailer regain lost power.
Finally, when the tva6 valve fails, air will leak out valve at a high rate, however as the valve wears it will become troublesome if you have a plastic pin. To replace remove trigger then remove roll pins that retain valve. Use a thick glove to catch the valve as you connect to air supply. Use caution because it will come out with force. You may want to reduce pressure to gun when you do this. Good luck with your repair and email if you have question.

SOURCE: Leak inside Bostitch N80 Nailer, won't drive nails

If the unit is leaking it most likley need a rebuild kit. Go to a Bostitch service center and ask for an ORK-11 kit. That is all the o-rings needed to do an over haul. Or just have them do it.

SOURCE: bostitch n80 does not feed nails

make sure that the feeder spring is not broken this stops nails or can jam them or cause them to skip. Some nail gun types work bette if you buy their brand of nails, but it could possibly just be dirty or maybe check the nail size. You should also have a way to adjust how far your nails are in the bucket where you put your nails, it should go up or down by spining it.

I have a bostitch MCN 150 strapshot that does not work in cold weather, under 50 degrees. Is there a fix for this?


Most likely worn orings in the trigger valve (# TVA14). Cold weather usually does not affect the gun, however using wrong oil would. Replace the trigger valve and /or try using power steering or brake fluid as lubricant for your gun during cold weather and regular nailer oil during warm weather as these other fluids may have a long term effect on the orings (cause them to swell slightly). You can test the other fluids for long term effect by placing an old oring in a cap full of oil for a week or so. I use two orings of the same size, one for control to compare against the one in the oil. No big deal. Also check for worn parts in the safety foot and /or worn trigger. If you have a single shot trigger (light color plastic) try using the bump fire trigger. Good luck.

My bostitch bt1855 nail gun worked fine, until it started to dry fire 2inch nails. No problem with firing quarter inch nails. Any ideas?


Have you serviced it recently? and is the gas in date? The pistons do dry out and have to be oiled with special oil.

My bostitch N88RH is not firing nails


May occur when headvalve or driver is stuck (will usually make a pop or click when tigger is depressed), or tigger valve has failed or safety not actually touching trigger firing pin. Easy test, remove nails, remove trigger by pushing out 3mm roll pin or bolt to expose the firing pin. Pull back nail feeder and place the nose against piece of wood ~ depress trigger with very quick motion with finger. If it fires, reinstall trigger and adjust safety foot so that the firing pin is pushed all the way in. If does not fire, replace trigger valve (usually tva6) or remove trigger valve and replace the 3 orings on the inner plunger. If you hear a pop or click when you do test above, remove head and lube the headvalve orings with white grease or silicone paste.

Pull the trigger, no nail, only continuos air until I release tyhe trigger. not jammed, gun is clean, very new. acted that way right out of the box then it worked and then not and so on, worked...


Safety foot and lever inside of trigger are not pushing the trigger pin all the way in. To verifty that the gun will fire, remove the nails to allow for dry fire. Remove the trigger to reveal the trigger valve. Hold the gun against old coiled rubber hose or soft wood. Very quickly depress the trigger pin all the way in. If the gun fires, adjust safety foot and trigger so that the trigger pin is fully depressed when your bump fire. If the gun will not fire after adjustment, remove the head and lube headvalve/orings with silicone paste lube.

My N88rh shoots two nails at a time


N88rh uses a full round head plastic collated nails which are spaced apart enough that the driver cannot hit two nails at once. If your are using other nails that fit into your magazine that are closer together you may in fact drive two nails at once. If, however you are using the correct nail and the nailer shoots twice, then you probable have a very sensitive firing valve. You could change the TVA6 valve or change the actual trigger. To overcome this problem of double firing and you do not want to try changing the firing valve, you need to change the trigger to sequential type instead of bump fire type. This trigger is usually white and will only permit one nail to be fired. Check www.toolpartsdirect.com or bostitch.com for parts. Good holiday

Sometimes fires 2 nails at once not all the way in and sometimes dosen`t shoot a nail in at all. I only use Bostitch nails


you would need to check the driver/piston for problems and make sure that you are using the right guage nails. Let me know what you find and I will try and help further.

Bostitch nail gun loss of pressure, won't fire nail


Hello. I can help you. The nail gun you have uses 18 gauge brads. I would use only original Bostitch 18 gauge.

The one MM of difference you mention is the reason why you do not have the pressure you did have. Get rid of those 31MM brads and get the 18 gauge. Home Depot carries the Bostitch line. I would go there or to homedepot.com
