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).

I cannot see any advantage at all. Timber dries out and cracks . Timber is very prone to ignition from fires and cinders when dry. nails rust and glues fail with time. metal lasts for a life time and comes in a variety of colours. doesn't burn and will resist higher wind speeds .

does Hitachi make or is there made a 4" router lettering kit?

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

Hitachi Tools &... | Answered on Oct 24, 2018

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

Check the date of the bottom of the gas. With the gas removed when you fire it you should hear a faint spark sound from the top. If gas is in date try putting it in your pocket for 10 minutes to warm it up. Open the front and make sure the piston is pushed all the way up into the machine.

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

Google (hitachi)(NR65AK)(manual) without parens.

Check the date code on the bottom of your fuel - it doesn't matter if it feels full or that you just bought it, many stores don't rotate their stock. The #1 issue with these is bad fuel.

This probably is the problem,

The cylinder that the piston moves up and down inside is probably to low, and not making contact with the rubber piece in the head cap.

The cylinder has a spring that allows for movement up and down, take a pliers and gently pull up the cylinder if it does not move freely on its own. It will stop when it reaches the cylinder plate ( the part with 2 screw holes for easy removal). Be careful not to mar the cylinder though.

When reassembling the cylinder should make contact with the head cap. Hope that works!

just wondering if you are putting enough down pressure
on it before you pull the trigger.?

Hitachi Tools &... | Answered on Jan 07, 2018

1. Have you adjusted the air pressure to at least 100 PSI?
2. Have you cleaned and lubricated the gun per manufacturer's instructions?
3. Are you driving nails into hard wood (oak, walnut, etc.)? Some guns are simply not powerful enough to handle extremely hard woods.

Hitachi Tools &... | Answered on Dec 08, 2017

1) Oil it per the operating instructions.
2) Use only high-quality fasteners. I recommend Hitachi or Bostitch, although those from Harbor Freight Tools are largely trouble-free.
3) Make sure nails are properly inserted in the gun.
4) Check to confirm that your gun is receiving adequate air pressure. With that nailer, I'd suggest 95-105 psi.
