It's probably just stuck. This happens all the time with a different nailer that I have. Remove air hose. Give it a good bang on a block of wood and try again. If that doesn't work the first time, try banging it in a different direction.

The kits for the senco guns, have all the o-rings and seals needed to stop most leaks, no hard parts. You have to replace all of them, no oil is needed, but it needs to be clean, some have little tubes of grease for the o-rings. I'm sure the other guns are the same way. Some of them will give you a fit. I had a senco sfn1, totally rebuilt, still leaked, tried it again, still leaked, called senco, they said send it to us, they fixed it for free, but never said what the problem was. Some times the triggers go and you end up building the whole gun for nothing, and the trigger still leaks, they are the toughest to spot. I have seen a lot of complaints about paslode. We tried them all in our shop, and the senco was/is the best, So we fazed out all the other guns and kept the senco, so all the nails were from 1 dealer, all the parts, we weren't looking all over town for a box of staples.

dead give away that the motor is done, there is a very specific smell when the windings burn, would have to say you got a bad one.

Needs srtrip down and seal kit fitted. Ensure all new seals have rubber grease applied

sudden loss of capacity like that usually indicates broken or leaking valves in the head, or a blown gasket between inlet and discharge side of the head. if nothing is found there, then look at the piston and or cylinder bore for damage.

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.

Generally speaking an O-ring kit will resolve this type of problem. Check with your local lumber yards that sell Bostitch products. They may have a Bostich Day at which, for a purchase of nails or some other Bostitch product, the manufacturer will give up to 2 tools a quick overhaul including replacing the O-rings.

usually when these pumps suddenly lose their capacity like this, the first place I start is to remove the cylinder head and look for a broken valve, and or blown gasket between inlet and outlet side of the head.

Usual cause is you have failed to adequately lubricate the nailer.

Put at least 12 drops of air tool oil in the air inlet.

Force the pin back and cycle the unit once.

Put more oil in and repeat a few times. This may restore operation.

Do not fail to lubricate since the seals could be damaged if run dry and then you have to rebuild the unit.

check the crown size. some are 9/16 others are 1/2

Normally, yes- depends on how old the nailer is. But first, let's ask: are you getting at least 90 psi of pressure to the rig?
If so, you may adjust the nailer with an allen wrench, or with a thumbwheel, both of which are located near the firing mechanism.
IMPORTANT: before you mess with it, be sure no pressure is left in the unit, otherwise you may be on here asking how to extract a framing nail from your skull while your hand is attached!

remove the roll pin holding the trigger latch assembly and then the 2 roll pins on the valve itself. Get a shop rag and place over the valve and then while holding the collar on the air fitting hold the rag in place and push the fitting onto the air chuck and the trigger valve will pop out. the remove the 2 pins holding the bottom of the valve together and remove till you get to the split o ring on the assembly.

It means you have to replace the trigger valve or the O-rings in the trigger. This fepends which model you have. A Bostitch service depot will have the parts.

the o ring in the trigger valve is split. If you can find one at a local shop they are sometimes called a "purple o ring" from the kits. If not you will have to replace the whole trigger valve assembly.

Hello, First you should try to use some aeresol spray lubricant, such as PB Blaster, or WD40 and squirt a couple of short burst of that into the air fitting on the end of the nailer/tacker. That might help loosen up the excessive oil that has likely congealed inside the nailer.

Let it sit for a good 15 minutes so the spray oil can work it's way through the nailer. PB Blaster is one of the best penetrating oils around so if you can, use it, but you can try the WD40 or any other good quality aeresol spray, penetrating oil.

After the 15 minutes has elapsed, connect the tool to the air supply line. Do not put any fasteners in the tool yet. We just want to see if it'll work and cycle. Give the trigger a try, while putting the nailer/tacker against a piece of wood. If your tool won't cycle unless it has fasteners in it, then put in a small amount to try it, again with the wood piece.

If that doesn't work, you'll need to disassemble and clean the tool. Here's a weblink to Stanley's site that you can enter in the model number of your particular tool and obtain a service drawing and documents for it.

When you begin to take the tool apart, use your cell phone camera or a digital camera to take pictures of each step as you disassemble it. That will help you when you go to put everything back again, as you'll be able to see exactly what went where and keep from making any mistakes.

Hope you find this Very Helpfu and best regards!

I purchased a generic one at home depolt

Probably one of four things:
1. Bad quick disconnect fitting (though these usually fail open (leaking)
2. Bad Regulator (if equipped)
3. Check for a shutoff valve on that line (sometimes they are integrated into a plastic manifold, and may not look like a traditional valve)
4. If the unit is older, rust may have plugged up the piping - you may have to take it apart and clean it. (Depressurize first - there should be a drain **** to relieve the pressure)

clean the tar out of the feed mechanism, you dirty roofer.

I would go to Bostitch.com and type in your model number for a parts explosion. When you get that if you still need help send me a message and I will do what I can. Its not that hard.
