Default Need Help With Brad Nailer...

I have a PC BN200C brad nailer. I haven't used it much and then only with 5/8" brads and have had very little trouble with it. Once in a while I would have to open and close the magazine to get it to feed, but when that happened I never saw any evidence of a brad being jammed.

Today I needed to use it with aome 1" brads and ran into trouble. At first, my problem was that I could only drive one brad then would have to open the magazine and close it before it would drive another brad. Sometimes I would have to do this several times before it would drive another brad. For a short time the gun drove the brads with no problem, maybe a dozen but then went back to the old problem.

Then later it would not even drive a brad, the gun sounded normal when I fired it but no brads were being fed. Nothing is jammed that I can tell, I'm about to ash can the darn thing a buy another one, but thought that I'd ask first here on the forum and try calling tech support for PC.

I have two friends that that have this same tool but they have not experienced any problems with their's.

One of the friends asked me if I had been putting oil on the air connection after each use and I have not, didn't know about that need, so this might be my problem.

disassemble and clean the magazine...
glue resin from the brads has built up in the track...

brads are over sized...
change brand of brads...

could be the feed spring is hanging up or weak...

This would have been the week that I'd have finished chewing thru the restraints...
If only new layers hadn't been added....

Shorten the supply hose ?
Increase the pressure ? Minimum of 75psi ?
Bigger air hose ?
Sufficient CFM ?

You mentioned not oiling...put a few drops into the air nipple at bottom of gun...hold it upside down...

Is the magazine full ?

...its against the law to throw tools out... :-)

Jerry this may be way off course but I'd like to share my experiance .i bought a package deal with 2 PC Brad nailers and right off the hop the smaller one did squat . We pulled the back off at homedepot and checked that rubber diaphragm and it was jamming . He pretty much inspected it and reassembled and it worked ever since . I was thinking that when you put the magazine back into position that the small jarring made the diaphragm release again?
It didn't seem that intimidating when it's disassembled , so I would remove the back case out of curiosity and inspect it . Can't remember but I don't recall him adding any lubrication when it was apart . But they rent them out and that's the first thing they check when they act up.

I'm wondering if you just need to clean it ?

I don’t always insulate , but when I do .
Ok ,I never insulate

I had the same problem. It took a while, but I found a microscopic split in the tip of part #407A in the drawing below.

I seem to remember that the price of the part was $40 or more. I sold the nailer at a garage sale for $10 and bought a new nailer

Try moving the heads of the nails up to the next highest groove. I have one nailer that works like that on a couple of sizes.

Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.

When you first got it, it worked. __> So it didn't have any manufacturing defects as some described. (No crack in a cup or piston head.)

Try cleaning and oiling first. You have never oiled it and you don't use it much... So I would suspect the seals are dry and sticking... If not too dry, then it may be minor...

Let me explain-- This is something that was drilled into me as an apprentice and I, in turn, drilled into my apprentices. Most of the seals in an air nailer are just rubber o-rings. If you don't keep them oiled... One thing that happens is that they run dry and start dragging, then wearing excessively. With being dry and heat (the OP lives in a normally hot arid area) the seals sometimes get gummy. Other times, if really dry, they will get brittle and split or chip...

Everyday for many years, I started each day with a few drops of pneumatic oil in each gun I used. I usually ran thousand of nails, staples, brads, pins, etc. Most guns, when the seals wore out, I either bought kits or went to a hydraulics supply and bought o-rings. Sometimes you will run enough nails through to need a head, but I doubt the OP has shot that many nails.

- If it were firing, but weakly (not sinking nails all the way home)... then oil or worn seals... just like if the air pressure were not enough.Then you would hear in "how" it fires. More so if you hear a slight hiss as it fires. ...Or not a crisp op when it fires.

But if it sounds as if it is firing crisply, leaving a divot from the head into your work, but not firing a nail, then check the magazine mechanism and/or the fasteners.

I think that what you did is the best and simplest remedy, I have better things to do than to mess with a tool that isn't working right and I that I don't understand, especialy one that is not expensive.

I have several finish nail guns I use all the time.There are a couple of thing s to check which some of the guys have already said. Oil is one put a few drops in the air nipple and because you have not been doing that turn the gun up and put a few drop in the tip where your brads com out.Check your air pressure.And a problem with the nails themselves I have used different brands of nail through the years sometimes cheaper nails have to much adhesive on them that flakes off and jambs the gun. I have also gottan a bad batch of nails in different brands.
Hope this helps.
