Your description makes it clear that it needs a head rebuild kit. You can order this from Hitachi, or send it in to local Hitachi center. Good machine, straightforward repair. If you are a little handy, you can do this repair yourself. remember to oil the gun frequently to make your repair last longest. Farmerbear at FixYa

Nail gun leaking air at trigger


Worn orings always results in leaks/low power. On some nailers, better to replace whole trigger valve as seperate orings (very small) are hard to find and usually not in repair kit. Low power is usually worn driver oring. Easy test, remove nails and point nailer up then down again. If the driver seems to move up and down within the cylinder, time to replace oring/s. Look for repair/tune up kit that contains all the orings in the gun.

My nail gun won't fire nails and is blowing It


Stop using it and take it in for service. If it is leaking air then an o-ring or seal may have failed (most likely guess) and it needs to be replaced.

My RN175 shoots you think it shot the nail, but when you move the gun to shoot the next nail the nail you just shot falls out the end of the gun. What could cause this?


The driver is coming down far enough to break the nail off the strip but not far enough to drive it in. This could be caused by any of the following:
- The driver is broken off and too short to drive the nail
- The driver is bent and doesn't travel all the way down
- The seal/o-ring on the piston is damaged and air is leaking past it
Any of the above will require you to remove the head and inspect the driver, piston and o-rings or have a service center check it out.

NR90AE Nails jammed how to remove


New user will jam the gun/ nails because gun was most likely not bump fired. Placing the gun then depressing trigger will usually cause double fire in the hands of new user. New user should practice on scrap lumber bump firing at many angles till they get the idea; or give them a training period with a nailer that has a single shot trigger (they may develop bad habits with single shot however).

When using n60 nailer, one nail goes all the way in, but the next nail only goes halfway in and the some don't go in at all. Don't know what's wrong.


Worn orings in gun and the trigger valve can/will cause problems as you describe. Remove the nails and leave open the latch. Lighty tap the nose of the gun against coiled rubber hose. The driver/piston should stay in the top position (if the driver is down or comes down after test, replace driver oring). Now push the nose against the rubber hose and activate/hold trigger, while holding the trigger/gun in this position, the driver will /should stay down under pressure. At this point no air should leak out of the nose of the gun. If air leaks out of the nose, examine the lower bumper for cracks ( replace as needed ). Finally remove the trigger and examine the firing valve pin. If it has a plastic pin, looks worn and wobbles from side to side, most likely needs to be replaced. If however it has a metal pin and it seems to fit snugly, do not change unless it is leaking air. Good luck

Your nailer is a very heavy duty nailer with very powerful blow. Works best with full size nails, not 2 inch range that are used in fencing, they are not spaced correctly for your gun (like hitting number 6 nail with sledge hammer). Open side door and remove the nails, leave the door open and dry fire gun against piece of rubber or old coiled air hose. The driver should return all the way up between shots and the feeder should move back then forward just as fast as the driver moves. If the feeder seems to move in slower motion then pull feed piston and replace orings and remove debris from feed cylinder. If the driver seems to stick out further than normal then lower bumper could be breaking up causing debris to enter feeder. Make sure that the driver is not bent and has a squared bottom, if rounded, remove and grind square. Finally adjust the depth control up or down slightly and bump fire for test, do not place gun on the work then fire. good luck

I have the 2 1/2 Hitachi for nailing siding. The nail gun had not been used for a couple of years, but now will only drive the nail half way in. Sounds like an air leak when driving the nail. I have...


Remove the nails and air supply. With side door open notice position of driver. Driver should be at top position with tip not visible. If driver is down and it moves within cylinder when you tilt nose up then down again, time to replace orings. If driver is down, it should extend past the nose about 1/4 inch (if driver is broken at the tip the end will look rough and nail will not drive in all the way). If driver extends past the nose more than 1/4 inch then lower bumper may be breaking up /cracked. Easy test for proper function. With nails removed and side door open, connect air to gun and dry fire gun against hard rubber or old coiled air-hose (with air connected and trigger depressed, no air should leak from trigger area, if air leaks when trigger is depressed, look for fault at trigger pin). Feeder should move back then forward in quick motion almost matching speed of driver and driver should not creep down between shots. No air should leak from nose of the gun (push nose against hard rubber and depress trigger and hold in this position, driver should stay down with very little or no air leaking out of nose, when you release trigger, driver will return). If air leaks out of nose while holding in this position, replace lower bumper. If a quantity of air leaks from valve in front of trigger, cylinder orings may need replacing or outer part of cylinder has fine scratches (remove scratches with 400 grit paper).

The dial on the top of the gun is most likely the depth adjustment for the nails, this should solve the driver damaging the work piece. Make sure the nails are the correct guage for the nailer you have.
