    this has nothing to do with the compressor. I have the exact same problem with my new dewalt frame nailer. After working for an hour with it it wouldnt fire, but air would rush out the trigger when I would try to fire. I took it back to the shop and they said Dewalt uses a grease that's too thick and tends to cause the nozzle to jam. He took it and fixed it, said he changed the grease for oil. Worked great, after using it for an hour again, the same thing is happening. I'm going back tomorrow.

    Point of interest. Both times I worked outside with it with below freezing temps. Both times I used it for over an hour outside. Both times it only stopped working the next time I went to use it the next day, after sitting inside.

    My porter cable nailer will not shoot nails. The pin strikes the board and leaves an indentation but no nail.

Not all 120psi air supplies are the same. Here are some differences. The pressure regulator has a great deal of effect on the performance of the air tool. Regulators are sold by the volume of air (cfm)that they can handle. The more cfm the larger the pipe fittings on the regulator. A 1/4 fitting regulator will restrict the air somewhat compared to a 3/8. Another difference is weather moisture is present in the air. Moisture will temporarily help seal the orings, however too much water in gun will cut the orings. The air hose and fittings will also stifle performance. Long small diameter hose will lower pressure at the gun. This can be measured by installing a guage on a T fitting on the end of the hose and watch the pressure as you fire the gun. Larger fittings and hose ID will improve performance. Finally, your nail gun should work on both compressors. To make your nailgun work at home, (assuming that there are no air leaks) lube the headvalve parts with silicone grease. (sold at lowes in plumbing dept) For best performance, replace the orings in the head valve, examine the plastic parts where the orings contact and look for wear and tiny scratches (use magnify lense). Replace these worn parts along with orings. Replace the head gasket and make sure that the body and the head-cap are not warped. Place sheet of fine sandpaper on flat surface, with cylinder removed rub the body of the gun on paper a few times to check for warp. Do same with cap. Parts are available at www.toolpartsdirect.com. Enjoy

I think that there is water in your compressor from condensation, it's getting the inside of your gun wet and it's freezing up. Just a guess.

I have a Hitachi NR83A3 framing nail gun. It won't drive nails flush. Adjusting the depth screw from one extreme to the other doesn't appear to help or change the driven nail depth. Any ideas?


Easy to check. Remove nails from gun and connect to air supply. Using hard rubber pad or soft wood depress and hold trigger and push nailer safety against pad and hold there. The gun will fire but the driver will stay down until you pull back on the gun and relieve pressure on the safety foot. With driver down examine the tip of the driver. It should look square and should extend about 1/4 inch or more past the nose. If tip is broken replace driver. If lots of air is leaking past the nose during test, also replace the lower bumper. Good luck

Paslode framing nailer: compressor powered, hisses but will not shoot nails, appears to be in the sliding mechanizism that touches the wood first before it will shoot, help


I've used paslode for years and whenever there was a "hiss" of air and no fire- it was o-rings- When were the o-rings changed last? And how do you know they are in 'good shape'? You can't tell by just looking at them. If that isn't the problem then I can't help. Just as an aside- do you oil the gun (down the air intake nipple) every time you use it? Lack of oil will wear out o-rings fast. Sorry if this isn't overly helpfull but most gun problems are o-ring or seal related unless you've worn out or damaged a mechanical part.

Hi,

Here is a tip that I wrote about the Paslode nailers and the problems that can come up with them.

I also have a link to the Paslode manuals which contain Paslode cleaning and troubleshooting guides.

If you need parts for your Paslode, there also is a link for a site that sells the Paslode nailer parts.

Paslode nail gun 325 black not firing


Any time these guns become intermittent or stop firing but the fan still runs, the first the to check is the expiration date on the gas cartridges. The do expire and this will make the gun work inconsistently or not at all.

My finish nail guns, 16 ga won't fire.


There is a little plastic piece inside above the trigger...usually this breaks. It touches a microswitch when the cylinder is closed all the way, allowing the nail to fire.

Paslode nail gun not firing


Hi,
Yes you need to oil driver blade piston.
You need to check for spark. With no nail or gas in it. Take of main cylinder(4bolts on top, 2 bolts on nose. And then put in battery. And then push upper switch(behind roller at top) and the fan will come on. And then pull the trigger. You should have spark.
Thanks,
Jeff
