I have a Senco clipped head FramePro nailer that is about 6 years old. For the second time now, it has started leaking air (not too much) out the exhaust port. The last time it happened, I had it in and the dealer repaired it and wrote it off to "These things happen". I really don't use it much. It may sit for a year without being used. I am very carefiul about oiling it every time I use it; twice a day if I'm working all day long.

I'm trying to decide if it's user error or if this really is one of those things. I'm wondering if sitting so long between uses is causing the seals to dry out. I occaisionally get a double shot, could that be causing a problem?

Any thoughts?

probably the trigger valve assy. you should be able to buy a repair kit and they're not hard to replace.

 

I agree with flopshot on the trigger assembly. Just as a question, being Senco, does it require oil? My finish nailers specifically say no oil since they have ceramic parts.

 

Yes it definately requires oil. My Senco finish nailer does not, however.

 

I have a Bostich framer that leaks air if it isn't oiled properly.

 

The leaking air is from a little rubber seal in the your nailer. I have many nailers and one of the is a Senco. After having it reapired once, I immediately realized that it was operator error. Luckly my foreman was the operator and not me. Anyway, we found that the trick is to oil it after we are done with it. It keeps the seal lubricated. We only use that nailer on special jobs. So it goes long periods with no use. This may help you. Good Luck

 

Check the O ring on the piston.. You should be able to get to it by removing the top of the nailer..

 

Well that sure makes sense to oil it when you're done! Do I need to run a nail or two through it to get the oil distributed?
