Review by richard

I bought 2 of the nr90ae from Lowes. I had them both break the same way so I took them back. One tore up in a week with the same problem. A couple of days later the other one took a dive the same problem. The o-ring breaks and the drive pin twisted sideways and broke on both the guns. I have never had so many problems with a nailer until these came into my possession.

Hitachi NR90AE

I just replaced all the o-rings on the trigger assembly due to air leaking around the trigger. I can't get it to funtion at all now. I tried to be real careful of placement of parts and used air tool oil on the rings. can you help?...
