I had used the new Cordless, Butane & Battery powered framing gun from Hitachi this past July to build a barn.
I can't say one good thing about it! It was the biggest misfiring POS I have ever used! After 4 hours of attempted use,
I went back to my old faithful Bostitch Compressed Air Framer and never had a problem. Yes, I was using Hitachi's nails, batteries and fuel cells.
I returned the Hitachi to the Lumber yard, they gave me another to try, it was the same way. They gave me my money back no
questions asked, and told me others have had problems as well.
