n80 coil nailer is a very powerful nailer used for hard wood. If the driver is setting nails too deep, adjust safety foot to the lowest level. Install safety foot no-mar boot to lift the gun even higher. If still too deep, most likely the lower bumper inside the gun is worn-out or cracked. Easy test. Remove nails and connect air supply. With trigger depressed, push and hold the gun against work (I use an old rubber hose tightly coiled up). This will fire the gun but keep the driver down allowing you to examine the tip of the driver. The driver should extend out past the nose less than quarter inch. If the driver is extending too far, most likely bumper is worn out. If a large quantity of air is leaking out the nose of gun during the test, indication that lower bumper is cracked. Good luck.

The feeder area of the nailer incorporates small levers on both sides of the nails. On the body side, the spring loaded feeder retracts and pulls forward the first nail. On the latch side small spring loaded arm/s hold the nails in place once they are pulled forward. Open the latch and push on both the feeder and the retanier for firm spring tension. On some nailers, due to wear, the grippers on the feeder tend to wear off allowing the nail to slip out of place. On other nailers, the feeder arm/shaft tends to wear and alows the feeder to move out of alignment (check if the actual feeder arm can move from side to side). The feeder shaft should move forward and back with no side to side movement. Finally, some coil nails are welded together with too stiff of wire. After the first nail is driven, the second nail will have one or two strands of wire pointing out not allowing the nails to move into position. After first shot, the two wires should be cut off or bent down out of the way. Good luck.

This is a bottom fire tool. (NV83A2) You need to hold the trigger down and then as you place the nailer to the wood the safety will depress and it will fire once. This is usually done in one, swift action. If you do this in the opposite way by placing the tool to the wood and then pulling the trigger they often will double fire.

Nailers that use strips of nails (one nail directly behind the other) will sometimes drive two nails at once and is caused by damage to the driver. The nails are so close together that the driver will hit the first and part of the second nail head. Coil nailers, as your an451, use nails seperated by welded wire making it very difficult the the driver to hit the second nail. Usually when a coil nailer shoots two nails, it is acutally the trigger valve that acutates twice (two very rapid fires). Two very rapid fires is caused by faulty trigger valve. I have seen a roofing coil nailer fire one nail and a second nail drops out of the gun. Caused by weak / malfunction of nail feeder or wire used to weld nails together is too thick.

Yes. Roofing nailers all use about the same size and spacing on coil nails. You will find that Harbor Freight is about 1/2 the price of Home Depot or Lowes for those nails.

Hi,
That would should any brand 15 degree wire coralated coil nails.

The F28WW takes 28Deg nails that are collated with wire, so your nails won't work in that gun. The N80SB is also a 28Deg nailer so your 30 Deg nails won't work in that gun either. Sorry about the bad news but it looks like your going to have to spring for new nails

I did some extensive research for you and found:

Sounds to me Like all you need is a O-Ring Kit, and Perhaps a New Driver.
Good Luck, I hope all this Info works for You.

Professional-grade varieties are automatic, and fire a nail directly upon pulling the trigger. A semi-automatic nail gun is more appropriate for beginners, since it requires a two step process: pull the trigger and then tap the barrel against the wood. This safety feature protects the user from accidentally firing a nail gun and injuring himself or others.
