23 gauge nail guns jaming3/28
Looking for advice about 23 gauge nail guns jaming. I have a grex, cadex and a harbor freight. I use high quality nails, try to keep the air pressure down. Don't oil the guns (as recommended by the manufacture). I have them rebuilt by repair shops......the harbor freight I just turn in on warranty. But they only shoot short nails. I have spoken with the manufacturers for advice. That is where I received the advice I posted above.
It's always the same story. When new they work great, then slowly start jaming. Until they the frequency drives me crazy!
So looking for good advice.
Should have mentioned that it is the nail being driven wrinkling up in the head .
We have an older and a newer Porter Cable gun(s) and use Porter Cable pins.
I've had 4 of the grex p630 for about 10 yrs in door department and install truck.
2-3 drops prior to use is all that's required.
I have always had a problem with that. Except the hitachi one I bought. The porter cable, grex, and bostich ones I have had have always jammed up and eventually had to replace the piston driver on them. The pistons never have enough grease in them and dry up over time. It starts with misfiring, then nail jams, and then finally the hammer bends off and breaks. When I realized this, I took off the back plate, removed the piston, greased it, re-installed it and never had a problem with it again. I do this with all my guns now. Even framers. ereplacementparts.com has parts for these
Thanks John!! Just the information I needed. I was having a love hate relationship with my 23 gauge guns.
So now, what is the very best grease to lube it with?
im not that selective with grease. i just use whatever is the the shop grease gun. But it looks like ingersoll-rand makes some. Makes sense, they are a top compressor manufacturer.
Grex: Couple of drops oil each day. Get the rebuild kit every year or two (depends how hard you work them) use good pins, pointed the right way. Guns are beautiful. I have never had a brand of pinner that could go years (under heavy use) and shoot as good as the day I bought it without some kind of maintenance. Parts do wear, especially the driver head where it impacts the pin.
I find I need to crank up the pressure for 2" pins. You have to watch the cut in pressure on smaller portable compressors. If I need to drive more than a couple 2" pins into anything harder than drywall I bring one of my larger portable compressors.
I would also check the min/max pressure of shop air with a gauge at the gun. If the compressor cuts in at 95 PSI, with 100 feet of pipe/hose you could be looking at a lot less at the gun.
Jay Miller...where do you get the Grex rebuild parts at? Do you just replace just the driver or do you go ahead and replace o rings and other parts too even if they are ok?
