Should be a little roller on or near point where nails come out. Roll right for deeper or left for less

Place two drops of light oil into the gun at the air inlet, and re-connect the hose. Fire your gun several times into scrap wood.

Since I am sure that you are using an air source that you know is working I would suspect a broken o-ring or a jammed mechanism.

A broken o-ring is usually accompanied by a hissing sound as the air escapes pass the seal.

If the mechanism is jammed the unit will act as if it is not connected. Disconnect the air source and check for a jammed nail. Also check to insure something is not preventing the safety mechanism for disengaging when the unit is pressed against a board. If these things out fine the unit may have seized up. For this or the o-ring repair take your unit to a service center (unless you are very handy).

Framing nailers can be very dangerous when they malfunction, so you would want this repair done correctly.

There are two areas around trigger that can leak air. Spray soapy water on trigger stem and/or plunger valve. If leak is at trigger stem check vinyl ball. If leak is at plunger valve, most likely worn or broken oring inside of gun. Remove head and pull outer ring to reveal two orings. A worn outer oring will cause leak at plunger. If orings are ok on outer ring, pull cylinder and check for scratches where orings contact. If scratched, sand with 400 grit paper untill smooth and repack gun with oring kit. Good luck.

could be you have a piece of a nail stuck in the nose assembly, the driver is worn and make sure that you are using the right nails. Let me know what you find.

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.

Have you disconnected it from the air source and deep cleaned the nail gun? Sometimes even a tiny bit of dirt can block the rails the rod runs in. Once cleaned add a small amount of oil to the rod runners.

Test the volts and amps of the battery after charging, then try to shoot nails then test again after the blinking orange light. Battery is failing, they only have a certain number of recharge cycles and are also governed by age degradation. https://www.google.com/search?q=hitachi+nailer+battery+problems+and+solutions ..

It is possible that the oil you added to your Hitachi pin nailer isn't the correct type or that it has not been added in the correct amount. You should refer to the manual that came with the pin nailer to determine the correct oil type and the proper amount to use. If this does not resolve the issue, you may need to take your pin nailer to a technician for repair.

oil it --few drops especially in ram

This is the Cars and Trucks section of Fixya. You might get more answers listing in another area of Fixya which more closely matches your device.All things considered, maybe apply air pressure and stick the unit under water in a utility sink or big wash tub. Air leaks would bubble like a hole in a tire tube.

LEARN TO USE THE SPELL CHECK FEATURE ON YOUR DEVICE . THERE IS NO SUCH THING AS A TRIGGER VALUE

I know nothing about these tools but Hitachi produce quality gear that isn't usually prone to intermittent faults. If I was faced with your situation I would check the power cord for internal breaks and check the internal connections and then investigate the functioning of any safety device that might be incorporated into the design - such a powerful tool would surely have safety built in or modern legislation would never allow them to be used on site. It was just a sort of gut feeling as it seems to be the built in safety that fails on many tools...

I've had that happen before and what I found was one of the Staples or nails had misfired and wedged before leaving the gun. read the manual on how to get to it for that particular model and also it might be a good idea to adjust your pressure accordingly to keep it from happening again. If the force isn't set proper then a nail could Jam , block the mouth and not allow any other nails to exit. It's very easy to do and not that hard to fix once you've done it at least once. Good luck.

The number one issue is bad fuel - even if you just purchased it, turn the cell over and check the date stamped on the bottom (often stores don't rotate their stock) If the fan starts when the nose is depressed but there is no spark then I would investigate the spark wire (make sure there are no nicks or cuts that may short to ground) and the ESU (Electronic Spark Unit).

Have you kept it properly oiled? It might be jammed because it's too dry.

Sounds like it's overly dry; needs oiling. Or there is something clogging the air lines or the air chamber inside the gun.

It sounds like you're producing difficulties yourself by attempting to solve this problem rather than seeking at why their can be a difficulty inside very first place https://www.fliptite.com/
