Repairing a Bostitch Framing Nailer

[Augus7us]

Hey Guys,

I have a framing nailer from Bostitch that uses the coiled nails. I'd like to use this for building some walls in my shop but when I connect the air, its clearly got a leak somewhere. Sounds like it is coming from somewhere near the front of the gun or by the trigger.

I looked up the manual and it says this could be a bad oring. That sounds logical.

Here is my issue, I've never taken a air nailer apart, I have my paslode but its pretty straight-forward. Is it difficult to replace a few orings in one of these? Also my other concern is safety. I don't want the thing exploding parts in my face. Do you dial the air down to something harmless when testing them? Or is there any other precaution I should take to test it?

I'm open to having stanley fix it, but I'd like use it this weekend and if its an oring I could be back in business tonight if its not a hard repair. But I don't want to keep track of 100 little pieces if these guys are complex so I thought I'd tap the forum to get you guys thoughts.

I didn't notice a model number on it but his is pretty much the same gun.

They used to have rebuild kits on Ebay. First figure out the model number. Try searching for your model number + rebuild kit.

There are dozens of videos on YouTube to illustrate how to disassemble and rebuild a Bostitch nailer. I'd bet it's an o-ring as well. If you are mechanically inclined, I'd give it a difficulty rating of 3 out of 10.

Look up the model number and find the "exploded diagram."

They are really basic inside, kind of like a single car cylinder and piston.

I have a Paslode F350 that my BIL dropped off a 6' ladder while helping me on a framing project and started hissing air near the top. I took it apart and added some RTV silicone and that did the trick.

You should be able to fix it for the cost of some o-ring.

the boststich framers are known to have trigger issues , and there is a small seal in them that deteriorates , as well as orings. buy a kit and rip into it. pretty easy to do

Thanks guys, about to head out to the shop now. I'll try to find the model and a rebuild kit.

I use hitachi framing and coil nailers but they are all fairly similar.

If you haven't used it in a while give it a squirt of oil and try to fire some nails. It might have just dried out since you last used it.

If that doesn't do it look up the model number on ereplacementparts.com. They have the schematics so you can see how to take it apart and identify all the pieces. I've ordered a lot of parts from them and been happy. Fleabay can be hit or miss, you might get some knockoff chinese parts. Orings might be ok but I got some crappy nail tracks a while ago, not worth it. Your local hardware store might have the orings too. I buy them in bulk because I rebuild/repair guns often but if you only need a few it's worth it to pay a bit more to just buy what you need.

Ive rebuilt my trigger about 2x
mines the stick framing nailer

There are Chinese trigger valves on eBay for about $10.00, last time I checked. They fit most Bostitch nailers......except mine, which was only available from Bostitch for about $50.00.

Sounds like the trigger valve. easy fix, inexpensive. I'd start there, first. the Stanley part TVa6 might cost close to 30 bucks or a generic replacement about 10.

Thanks Guys.

Regarding the testing now or after the repair; are there any safety concerns attaching air and trying to fire it? Or doing that while its leaking as mentioned above? I don't want the things exploding little parts at me.

The repair is a five minute job. Just make sure the air hose is disconnected!

Mine had a bad seal or o-ring by the trigger. Order a replacement from I think Amazon. Watched a youtube video on how to do it and it was super simple. Had never taken an airtool apart before but it was very easy to do and works fine now with no leaks.
As finn said, make sure air is disconnected obviously and take the nails out.
Not hard at all! Mine was a Bostitch coil framer as well

Very simple to repair. As said, the trigger valves gets leaky. Just buy the new cartridge.

On my N80SB there were two versions you could set it up for: bump trigger (contact) and finger-pull (sequential trip) Since most homeowners aren't doing production work, sequential trip is fine and safer. See http://www.aconcordcarpenter.com/nailgun-contact-vs-sequential-trip-triggers.html

no, it's pretty simple and hard to screw up.

They are designed to run at 80 psi, but some people go to 100.
