Porta Nailer does not drive nails. Its a manuel model. When you swing the hammer to drive a nail down, no nail comes out. Its probably a simple replacement part. Do you know what part can it be?

First thing to check is ensure there is not a jammed cleat in the nose or magazine preventing the nails from advancing all the way forward.
If that is not the problem, most likely you have a broken driver blade (Part #33 on the breakdown)

Remove the ram cover, using an old blunted nail carefully drive the pin back to the up position. Disassemble the gun and inspect both the drive pin and the rails for metal burrs file them off if necessary.

More likely an O-ring. When they spring a leak, you buy a kit that contains all the gaskets and O-rings and replace them all. An easy job. Hope this helps.

You broke the "hammer" you can open the housing and replace it, fairly simply. You can buy replacement parts at most large scale hardware or tool stores. The task takes about 10 min, and some simple hand tools.

I just finished 800 square feet of oak flooring with this nailer. You might have to increase the psi at the gun and make sure it gets a good square firm hit to set the nail. You can swing and hit the thing pretty hard, I hit it hard to set warped boards in place. I used 120 psi for best results, I tried 90 psi but had more misfires. The nail head only needs to set in far enough so the head is touching the tongue and so the next board will fit. The nail won't be buried into the tongue like you might think. If the occasional nail protrudes from the board you can use a nail set to drive the nail the rest of the way in, but I found that most of the nails didn't want to set by hand. I either clipped off the head with side cutters and folded over the remaining tab or did my best to set the nail if it wasn't long enough to clip. If it bends over really ugly, just carve a little wood from the groove lands on the next board to clear the nail stub. Removing the nails is difficult, it's best to let them be rather than risk damaging the flooring. Also, don't let the gun get down to the last nail. Sometimes if you try to fire the last nail on a strip it will twist and damage the flooring. Always keep a few nails in the gun just to be safe. Hope this helps.

For every nail that a normal human with a hammer could hand drive on his best day, a pneumatic nailer would drive and set twelve! That is no exaggeration. Although there is no need to go this fast, a reasonable speed would allow you to be 400 to 800 percent more productive. Nailing large subfloors and roof decks is a breeze. Hours worth of work becomes minutes.
