Works good with Red Paslode Fuel Cells December 15, 2008
P. Baron
I had some problems with this until I started using the Red Paslode Fuel Cells. The Hitchi ones wouldn't work at 6200'. Not having an air hose is great. The rafter hook is very useful. I bought a reconditioned one and am very happy with it. Don't let the negative reviews scare you, once I started using the Paslode Fuel Cells it worked fine.

Worthless November 25, 2008
Scott Young

This Hitachi gas framing nailer is worthless.
It says it will drive a 3.5" nail all the way in but even threw soft wood it leaves the nail stick out half an inch. so I bought 3" nails and it sinks them all the way.
The gun doesn't shoot any nail about 1 out of five times. I can hear the gas chamber's fan turn on but no nail comes out. I tried a new battery and new gas cartridges all to no avail.
I am building a barn and will be walking around in rafters. I can't have a tool that sometimes works.
DO NOT BUY THIS piece of junk. I had a paslode before and it worked fine.

Faster to hand nail August 9, 2008

I purchased this nail gun for a roofing job that required a total reframe of the sagged structure. I was excited to avoid the hoses all over the place and the sound of the compressor over my stereo.

The description says it shoots 3 1/2" nails. It does shoot them, but only 20% actually go in all the way. The depth adjustment was as deep as possible and I tried everything to get the nail to fully lodge into the new lumber. I ended up having to go back over the entire structure with my framing hammer and spend 30-45 minutes setting all the nails.

When the framing was complete, I thought I'd be home free with the sheeting nails at 2 3/8". The gun misfired and misfired and misfired some more despite changing nail types (I bought nails at Home Depot AND the ones on the Amazon detail page with no difference). After the gun stopped firing completely, I quit and hand nailed the rest of the sheething.

The reality with this gun is that a good framer can hand nail faster than this gun can shoot nails. Between not sinking the all the way and misfiring, the tool is more trouble than it's worth. I returned it and purchased a basic Dewalt pnuematic framer and have had much better success.

I wouldn't recommend this gun to anyone unless you enjoy frustration, slow results, and the constant desire to throw this tool across the parking lot.

I've had this unit for 2 weeks now, doing some roof and wall framing. Granted, it doesn't bump fire like an air nailer, but that's not a requirement for me as I'm a methodical type, so an extra 10-seconds to nail off a row of studs is not an issue. The gun works well, is plenty powerful, the 3-1/2 inch ring shank limitation is known, so I work within its capabilities. I find you have to teach yourself the right amount of pressure it takes to enable firing, and I don't give it a second thought now. VERY pleased with the convenience of no hose and 40-lb compressor to lug upstairs.

Great Gun, lousy gas April 17, 2008

This gun gave me a lot of headaches...it would fire a few nails, then nothing. I would take out the gas canister, press it manually a few times, then reinsert it. The gun would shoot well for a while, then nothing again. I found that the problem was with the Hitachi brand gas. For some reason the gas metering valve would stick or clog, and not supply enough gas for each shot. The solution? Red canister Paslode gas. I so far have gone thorough 3 of them with no hiccups from full to empty canister. This thing is a great tool, no regrets as long as I use Paslode gas.
