Slam fire where if the trigger is pulled the staple gun will fire as soon as the
safety release is pressed as opposed to trigger fire where it would not fire until both the
safety was released and trigger was pulled was the two options I remember in buying the gun. This for the primary user of the shop manager who is at best trained as a garage type carpenter when I bought it, and the little need to have speed in stapling as if on an assembly
line was what I bought. Very important setting and concept in buying such tools out of
safety. Also one to
mark the tool as so you cannot say get a staple in the
leg. Or
in one case a 12d
nail thru the finger I once in college pulled out of someone’s
hand - this given he didn’t know
safety and either double fired in it moving, hit something with the
safety before he was ready or missed in a
nail hitting his
hand supporting the material below that of his aiming
point.
I digress, this tool was set up for as it were trigger fire. 20 to 30PSI too high is correct in my own assessment in what was wrong here and is still wrong here. Amazing that this new tool said about 90 to 100 PSI yet older guns work fine at this pressure. This as with other types of narrow
crown and finish
nail guns also don’t operate in such a condition given the pressure. Yes, it causes problems with the seals and pads or where they buffers, but overall they operate. The Larger M-gun of a newer version has problems with higher pressures it would seem.
So what to do? In the past I have used in-line regulators on the tool and even did so for this tool. They work sufficiently in keeping the volume up but one has to know it needs to be added to the tool before use. One must also know the
system pressure before using the tool, and that of the tool’s seeming operating pressure. Requires a certain knowledge of what one is doing.
This granted at one
point I had a dual air for air’s sake and dryer and oil regulated
system set up in the old wood shop for use with pneumatic tools. Shop manager came back and quickly removed such things way back when in addition to going back to using the table saw table top for a fabrication table with glue drips and
etc. Anyway, given a lighting shop, it was said that such hoses that might be
fed by an oiler would potentially wind up spraying oil within them onto the lenses of lighting fixtures. Valid
point unless marked as wood shop hoses as opposed to normal hoses. At that
point it’s no worse than plugging a 30" industrial fan into a 50' 18/3 extension
cord. Urr, gee... never mind this is your job not your career, just ask before you do such things in the future.
New wood shop doesn’t have oiler’s either and it’s doubtful the drips of oil I was also raised on given other than best circumstances where an oiler was added to the
system. Also seems like they are also over pressure this given I wander over there at times in saying to those that mention that I’m in the wrong building, that I’m giving up lighting and going back to my carpentry trade again. They often say something like great, best solution for the company as a joke response.
In still mis-firing, years after I bought the thing in it now having a home in a real carpentry shop I now get advice on it’s use by those who now use it. Gotta hold it in just such a way and it won’t double fire. This as opposed to a pressure regulator I will have thought of had I still been a carpenter for my living - believe my side of the complex still has some of them I made up for the tool available as with the oilers I also bought not in use....
Fascinating for me.
Pick up a tool I thought years ago I figured out the problem with and solved, and years later I pick it up again and it still has the same problem. Says a lot about the carpentry shop in that they tend to hold the tool in just such a way, this much less they didn’t add an in-line regulator to it before now. I’m now a lighting guy that has use of the wood shop due to real scene shop training, my recommendations don’t go far when it comes to their world.
Next time I visit their world, I suppose I should just dig out the in-line regulators. This given the various piston seals are no doubt by now blown. This much from the shop manager that teaches
safety yet screwed up the alignment of the drill press I also bought and now finally have in my department. This by way of getting a glove caught in the thing. Really injured himself good by doing that one, question is what was he doing wearing gloves while operating a
power tool? Those that don’t study history or their field are resigned to re-live the past. Not to say that the shop manager and or others are not tremendiously qualified to do their jobs, or that I want any other career path than I'm on, just to say stupid mistakes and ways of doing stuff tend to also be really bad practice at times. I fight my own bad practices in at times also being wrong.
Must remember to bring regulators much less pneumatic tool oil on my next visit to the new wood shop. Hopefully as advised the tool is not totally toast. 120# pressure on a 90# gun is the cause not just, gotta use it in just such a way so it will only fire one staple.
Believe this is the cause of the problem.
