   Correct, there is no depth adjustment on this model with the 'S' on the end of the mod. #.

   There is an aftermarket depth collar that fits on the nose of the gun.

   I suppose you are now gonna ask me for a link? Don't know the maker of this. Maybe someone here has a better recollection......

   Do you think i'll need it? Can you use any lube or does it have to be Hitachi specific?

    

   Thanks

   The A2 should have a depth adjustment.  I've never seen the A2S

   Here is the part to turn your nailer into a flush nailer http://www.bigfootsaws.com/newsite/flush_drive.html  They work quite well.  That is what we always used to use for sheathing and it works very well.

   Whenever you nail sheathing, aim to keep the nails flush.  It is just good practice.  But for the rest of framing, it'll just slow you down.

   Yeah Tim the A2(S) does not have the depth adjustment on the gun. Maybe just adjusting the regulator will do the trick. Other than sheathing over driven nails are okay when framing?

   Overdriving the framing is ok, just don't go crazy, just set the presure high enough that you aren't leaving a lot of nails proud.  That'll really slow you down.

    

   Also, I'd buy the part, its cheap, and that way you aren't adjusting the regulator.  I have just not had good success adjusting the pressure.  But many probably do.

    I know some try to set the pressure up on the compressor to get the tool to do what it really sisn't capable of doing but from what I've seen in my 17 years that's foolish. 

    You tend to blow out seals and do a lot more repairs to the gun than using the correct air pressure..

     The Hitachi is better in most regards to not setting nails proud.  I rarely saw carpenters need to pull out their hammer like they did with so many other nailers..

   The A2 would have been a better purchase in my opinion. The "S" model has the provision to change from contact trip to sequential trip with a adjustment collar. The onboard depth adjustment is well worth it. My older Hitachi's have a replacement nosepiece that looks just like the factory model but has a flush nailer device welded on. Available at larger tool stores. We use Senco gun oil in ours, but any brand that is for pneumatic tools will do. I have ten of these gems and one is over 20 years old and still running. They are a solid nailer.

   I have not used it. Maybe I should take it back and get the A2, I don't recall seeing there though (Lowes).

   Likely not. The NR82A(S) is what my nail/nailer supplier calls the Hitachi Home Depot Special. Still an excellent gun.

   Get the flush nailing nosepiece for doing sheathing and shear nailing.

   It really is just a matter of personal preference after using nailers for many years. I just don't like adapters of any kind. On any given day we are framing and nailing ply of one type or another, so I like what is most convenient. I live in Southern California and my local big box stores only carry the A2.

   I've had an NR83A2 for a few years that I got at Lowes. Has no depth adjustment. What's the difference between 82 and 83?Also, maybe you can help me with a couple things that have been bothering me about it. It's gotten so that I cannot put two sticks of nail in it without nails jamming constantly. I think it's because the track for the nails has spread apart slightly, and the second stick always winds up riding up on top of the first stick, and then the nails don't advance fully and it jams. Ever had that problem.Also, there seems to be no easy way to clear a jam. I always wind having to take the whole damn thing apart...Steve

   I've had the same problem on the last framing job I was on. One of the two NR83A2 nailers we used you could only load one stick at a time- our nail/gun supplier gave the same reason, the spread apart track. So, this must be a common ailment of this gun as it ages. God, I hated when I had to use that particular gun.

   Not to really beat this into the ground or anything, I pulled out the manual for my 1986 model Hitachi nailer, it is a NR83A. They made this one for many years. The NR83A2 has a depth adjustment and is contact trip only, all of our NR83A2's are like this. The NR83A2S has no depth adjustment and can be switched from contact trip to sequential trip. We do have a few guns that we had to spread the magazines on to run .148 nails, on those guns when you use .131 nails they don't track correctly all the time. Mostly though it comes down to brand of nail. We generally try to use Halsteel nails. Recently I put an after market magazine on one of our nailers so we could run .162 nails. It is a copy of a Supco magazine. So far no problems with tracking. For the problem of jams, I disconnect the air hose and take all the nails out of the magazine. Then I drive the piston back gently with a long nail punch or a small bladed screwdriver, once it is past the head of the jammed nail you can wiggle it out. This works 99% of the time for us. I don't remember the last time I had to take one apart for a jam. Hopefully Diesel Pig will be along to add something as he is the King of Hitachi.

   Thanks.I pulled out my manual too, and it matches what you say. But the sticker on the side of my gun says NR83A2. But it is most definitely the one with no depth adjustment and the collar for changing from sequential to contact nailing. I guess they just don't put the "S" designation on the sticker. Have you got a source for those aftermarket nosepieces and/or magazines?Steve

   I live in Southern California where the Hitachi is THE nailer of choice so the aftermarket has supplied us with lots of options. I will try to run by my tool supplier and get the name of the vendor of those parts. In the meantime, one of the posters here, Diesel Pig, lives on the East Coast and may be a better source of information. He uses a lot of Hitachi nailers. See if you can shoot him a message.

   If not already, try using Hitachi branded nails and see if that helps.

   Hey,
   Forgot to tell you that I fixed the spred out problem.
   The Allen bolt that holds it all together was loose.

   Good thing somebody maintains my tools, since I can't seem to get around to it...one of these days I'm gonna get my shid together, man!

   What causes it to "double", firing 2 nails when you just want one. It bump fires just fine but when I just want to squeeze one off, sometimes I get 2.

1. 
   Jeff_Clarke | Oct 04, 2008 07:27am | #12

   That's caused by a slow reaction time ;o)

   It's almost impossible to totally prevent double firing on that gun with sequential.

   I did get the NV83A2S at HD on special order.  Amazon has it too.

   How does that collar work?

   Generally, avoid squeezing the trigger when firing. Pump it and release quickly. Sounds a lot harder than it is, just need to practice. That being said, we always give the new guys a sequential nailer to use when they are starting out. Once they get a feel for nailing most like the contact trip, but not all. Worked with a couple of guys this summer that used sequential nailers and their speed was terrific.
