Hey guy, first post for me and hoping to get some helpful feedback.
i recently purchased a hitachi cordless framing nail gun (NR1890DC) and am having problems with it not driving the nails deep enough.
im in construction but mainly using this for my own projects – I first used it to put down subfloor after replacing rotted joists and it worked fine besides a few times it wouldn’t drive the nails deep enough after a lot of use but usually the adjustment would take care of that.
i am now replacing fence boards and using 2” (I think, maybe 2 1/2) and every single nail is only going in about an inch. After I shoot a nail, it makes a weird sound, almost like a clicking sound after the cylinder cycles.
Anyway any advice would be greatly appreciated. Sorry if some of the terminology is off or my explanation is unclear but just let me know if I can better explain it.
Thanks in Advance!
Send it in for repairs. Sounds like something is wrong with the mechanism holding the piston in air cylinder
Must be something wrong as my framer drives nails really well
I have three that have done the same thing. They have been in for repair for over two months. The repair station said design problem that Hitachi is working on… Kind of expensive to be parked…
Same thing is happening to mine. Not sinking nails much more than halfway (using 3” nails), and a clicking noise which follows.
Sent in to hitachi for repair, received it back a few weeks later and there was no difference, same problem occurred.
They claimed that they “recharged air cylinder” and “adjusted nail depth”. I believe they did those things, but unfortunately it did not solve my problem. I made the (terrible) judgment call not to get a warranty when I purchased this tool, so I am in a pickle not knowing how to have this tool repaired. At this point I would gladly pay a repair fee if I new the tool could be fixed.
UPDATE:
I received my tool back from the Metabo-HPT service center and the nail gun is working properly again, sinking nails perfectly.
Apparently it was a “X-Ring seal/gasket” repair that fixed the issue.
Also, they did not charge me for shipping or for the repair.
I have a 18v Hatachi NR1890 DR framing nailer and it powers on fine but when I go to shoot a nail it just powers off and that’s it. Anybody know why?
This gun is garbage. I had 4 and threw them in the trash. The pressure problem continued to persist after numerous visits to the service center. The issue is in a leaking pressurized chamber inside that empties after 2 weeks of continuous use. Eventually the service guy started blaming it on me and said he will not recharge to chamber anymore. I threw the guns at him and left.
