SOURCE: driver wont retract

check to make sure the head bolts are tight on the top, if they are it probably needs a rebuild kit from campbell housfield includes orings for the piston, gaskets ect. and instructions

You have one or more worn o-rings in the head of the gun. They direct the air to the proper parts of the gun to first drive the nail then to return the driver to the top of the gun for the next nail. Depending on the manufacturer and your model number, some companies make kits to replace the o-rings (always replace all of them). For some companies you have to get a breakdown of the gun and order each o-ring seperately.

You may need a rebuild kit of the O rings, and, for certain added lubrication. The return stroke of the nailers require that all the parts move easily and dried out or "dead" O rings are a common problem causing failure to return properly.

I have a Hitachi NR 83A2 nail gun, it still fires a nail, the firing pin retracts but then slowly comes out and stays out. Is there a seal kit available for this problem?


Sounds like you have worn valves or damaged o-rings. Unfortunately Hitachi does not make a rebuild kit for your nail gun. If you go to www.ereplacementparts.com you can find an excellent breakdown of your tool and either order the parts you need there or use the part numbers to search the web for prices and availability. Your tool is on the old side and some parts are no longer available.

My Hitachi nv65ah nail gun won't set nails into 3/4 trim. I have played with the turn/screw set adjustment and it is set for the deepest setting. This gun was purchased second hand off e-bay but


If every nail is stopping at the exact same height, a likely reason is the tip of the driver is broken off so it's not long enought to drive the nails all the way to flush. If the height of the nails is slightly different you may have worn or broken o-ring(s) inside the gun and air is leaking around the driver's piston or elsewhere in the gun so that the driver isn't getting full pressure. You can take the gun apart and inspect the o-rings. If you push the driver all the way down the tip should come flush or slightly past the end of the nose piece (not the safety tip). Parts are easy to find online or at a service center if you have one nearby.

I have an Hitachi NV83A2 it won't feed nails anymore. Everything else seems to work properly. After about 20 or so hits on the trigger it will feed the odd nail? I am puzzled as to which course of...


could be a couple areas to look at. First lok at the coil of nails and possibly try another one. Check the adjustment of the coil for proper feeding. If all ok there, remove the coil and get a block of wood and safety glasses. Open the door and "TAP" the nose on the block of wood and look at the driver does it fall down into the lower area without the trigger, if so the piston o ring is worn not allowing it to fully retract and advance the next nail. If not apply air and DRY fire the nailer while looking at the feed piston/pawl, it should snap back and forth, if not there is either a worn oring or debris in the air passage. Also the pawl should have resistance if you push outwards on it. Sounds like a lot but only takes a couple minutes to see where issue is. Let me know if I can help

Nail gun will not fire the nail. Compressor works fine. Hammer doesn't retract enough to hit nail? Cause, solution?


could be a jammed nail in the magazine nose area, bent driver blade or problem with the o ring being worn.

I have a Bostitch BT200 that is dry firing. It seems that the "hammer" is not retracting after it fires a nail. I have to push it back manually and even then it seems to dry fire a few times before a nail...


The check seal is what causes the piston to retract. Remove cylinder and examine check seal. It is a small band that covers a series of holes and should fit snuggly around cylinder. Other factors that have effect on piston retraction are, split/cracked cylinder, bent driver and lack of lubrication. This gun is tricky to rebuild. Make shure that all the parts in the head are placed correctly. The kit does contain all the parts that you need. Good luck

Hitachi NR83A2 nailer pushes next nail down


Are you using full round head nails?

The hissing indicates your O-rings are worn out and need to be replaced. This is not covered by warrenty and is common for all nail guns. Lots of kits are available on Ebay or your local Hitachi service center should stock them.

Hope this helps,

Cheers

Won't feed nail


This happens to my gun too. You probably need to oil the gun once in a while. Here is how you fix it:
Disconnect the gun from the compressor first don't wanna get hurt or anything like that. There is a pin that shoots the nail out well that pin is jammed so what you have to do is push that pin to the original position. using a flat head screwdriver would help you to push that pin back into place. Let me know how that turns out please. I pretty sure that is the problem with your gun. Make sure you lubricate the Nailer once in a while.
