My impression was that the nitrogen cylinder was a sealed cylinder (non-replaceable) and that the 3 seconds was the maximum time to repressurise it using the on board motor. The nitrogen is supposed to hold enouigh stored pressure (energy) to drive several pins. I don't know how well this would work in practice, but the tool is being sold as a commercial tool (hence the price tag), so my guess is that it isn't a significant issue.
So your saying the unit has a nitrogen generator run by a motor that can build enough pressure with an 18VDC motor to charge said non-replaceable cylinder? That's a good little generator! (Edit:
I've been doing some reading and it does seem as though the cylinder is self filling by re-compressing the released nitrogen. I wonder how long it will take before the inevitable leak will develop and the gun will need to be sent back to a service center to be repaired/replaced. I think I'll stand my my assertion that I would like to see more information and a further review. Senco has definitely not been forthcoming with information about these guns and their reliability or rebuildability).
Says the man who's pretty obviously never had to install skirting (baseboard) in confined spaces like under stairs cupboards, cellars and the like. That stink is really disgusting, not to mention toxic and bad for the environment. And why is it that many of the gas naiklers (i.e. passlode-type nailers) I've used steadfastly refuse to fire in the upside down position? Give me my cast iron (in weight terms) deWalts any day
Actually, I have used the Paslodes in all kinds of tight situations. It was never a problem for me, but then mine isn't as delicate or as frilly as others. Upside down use could be a problem, but then I do try to stay on my feet instead of standing on my head.
Oh, and if you think a Paslode is toxic, consider what will happen with a gas in an enclosed area when it starts to replace the low oxygen level there in the first place. Isn't there about 78% nitrogen (20% oxygen), in the atmosphere to begin with? Adding a few more percent nitrogen and at the same time adding carbon dioxide from breathing while depleting the oxygen content sure ain't (American Colloquialism
) conducive to a long and productive life. This is why the odorous chemical (ethyl mercaptan) was added to LPG and natural gas after the 1937 explosion of a school in the State of Texas, (BTW, that's in the United States).
PS: I just looked up the MSDS for the Paslode gas and it seems that it's no more toxic than the air you breathe in a downtown street area. http://www.paslode.com/uploadedFiles/cordless_fuel.pdf
