SOURCE: I have a bostich framing

The o-rings need to be replaced and/or the trigger assembly is defective. Look around at local lumber yards for a "Bostich days" promotion. Often with the purchase of a box of nails, the Bostich rep will "service" up to 2 guns for free. If this is not an option for you because of time, you can purchase the o-ring kit and replace the rings yourself. This is not a difficult repair. Also, be sure to lubricate the guns with pneumatic oil frequently as this will keep the rings lubtricated and prevent them from drying out and leaking.

Hope this helps,

Dan

SOURCE: nail would not shoot out

The problem that you describe is caused when the driver is not returning all the way back up to the top of the cylinder not allowing the nails to enter into position . You may have one of several problems including worn piston oring, bent driver, worn check valve, worn lower bumper, or low air pressure. Simple test is to manually push the driver blade back to top using a thin piece of metal that fits into bottom of gun. Be sure to disconnect from air supply when doing this. Good Luck

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: Leaks air around the trigger.

sounds like the trigger valve has a broken o ring and would need replaced. you can go to Bostitch.com and order one for it, they are not that hard to install.

SOURCE: Have a n80sb. not hearing

If the plunger has not fully retracted after the nail has been fired, this can happen. Try lubricating the unit. It is possible that there is a leak in one of the Orings as well. Check the site below for a complete parts breakdown diagram that should be helpful.

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

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.

On the trigger of my Bostich Spiral load nail gun AND my Bostick trim nail gun air is leaking profusely from the trigger. Nail guns were not in use for about a year. When I first used them this weekend,...


A nail gun works on compressed air.
When you hook the air hose to the gun it fills a cylinder with air pressure.
When you pull the trigger. the cylinder pressure is released onto a firing pin that shoots the nail.
The air pressure line is also connected to the trigger and therefore the trigger has to be sealed.

When ever using a nail gun, you add a bit of gun oil in the back of the gun (not 3-in-1motor oil, it has to be non-detergent gun oil)

If you haven't used the gun in a while, it is best to oil up the gun and let the oil run down into the gun.
If you use anything but gun oil, the seals will give out.

Your trigger seal has given out. It is probably an 'O' ring. You can access it by taking it apart. Look for the O ring.
Bostich makes re-build kits for the different guns that you can buy on-line.
Back when I was in construction, there were several nail gun shops that sold and serviced nail guns, and sold nails to the contractors. I don't know if that business model is still active or if you have to send the guns to Bostich service center.

My bostitch 1664fn finish nail gun blows lots of air out exaust


Open the front and clear any jammed nails that are there. Oil the gun, push the drive pin back in if it didn't go back in when the front was off and try again. If there are repeated nail jam issues, try genuine Bostich nails.

Bostich nailer N79WWblows continous air


If the nailer is passing air from directly out of the trigger valve, it must be replaced (P/N-TVA11). If it is passing air from anywhere else, (eg back cap or front ) it needs an O-ring kit (P/N- ORK11)
