Hitachi NR83a2 Wont Fire

Jetdiesel

Have a new, used 2-3 times, 83A2 framing nailer. Using it today, working fine, just stopped firiing, like it was jammed. Was not jammed, but everytime I pulled the trigger, a puff of compressed air came out the top. Changed the hose, tried a different nail, hooked another nail gun to the same set-up and works fine. Let it sit for 4 hours, still nothing.
Any suggestions?

Have you oiled it?

Yes, I have oiled the gun, always before using. It has maybe seen 4-5 clips of nails.

Where did you insert/apply the oil - on the nail gun?

Oiled the gun at the hose connection/fitting

return it. if it's that new see if you can do an exchange. i've shot 10,000 or so nails through an nr90ae just in the past few months and haven't had a single jam or misfire.

my ridgid roofing nailer is another story......

I usually put 10-12 drops in the first time on a new gun then 3-4 with each day of use.

Being it’s a brand new gun the only other thing I can think of is not enough air pressure. If your putting 100-110lbs of air through it and its not firing then take it back.

If it was a older gun then we could get into tearing it down and fixing it, but not a new one.

Thanks for the feedback, everyone. Not being overly familiar with nailers, wasn't sure if I was missing something obvious.
I did notice though that even though my compressor is set to 110psi, it looks to be overriding that and climbing a little higher, like 125psi. Could that do it? Gun is rated for 120psi max.
