SOURCE: nail gun will not shoot

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.

SOURCE: can I change the pressure on the nail gun?

Hi there .
First check if the nail gun have a adjustment screw . Depending on the brand could be in the front where the nails comes out or by the trigger. Second check the compressor by the air hose connection you should have a regulator valve with a gauge and see if you getting the right air pressure .
Hope this help

Why might my nail guns not work?


Have you lubricated either nail gun? If not, go to Home Depot and get a bottle of air tool oil. It's in tools by the compressors. Disconnect the air hose from the tool. Pour about a teaspoon of oil into the air inlet of the tool. Reconnect everything and try it 10-20 times with no nails in the tool. Then try it with nails. Good luck.

Miss fires and wont sink nails depth set deep and pressure over 120 psi


If no air is leaking from gun, miss-fire is usually caused by worn or too tight piston oring or lack of lubrication. Easy test. Disconnect airline, remove nails, point nose of gun up then down. Driver should stay in uppermost position. If driver moves up then down within gun replace piston oring and retest. Set pressure to about 100psi. Good luck with repair.

Hitachi nr83aa shoots out nail and it bends last inch of nail over


One problem may be your air pressure at the gun. It should be between 90 and 100 psi to fully drive the nail fast enough to prevent nails being left high in the work or bent over. Bent nails can also happen if you are driving nails into very hardwood or hit a knot in softer woods but not usually with framing nailers. Another thing to look for is a rounded off driver that is slipping off the head of the nail before it is fully driven into the work. The tip of the driver should be round (some have a crescent moon shape) but square to the sides. If you need a new driver the part number is 878-630, shop the web for one of these, they run beteween $80 and $100 plus shipping.

Nail gun 58-8434-4 will not drive 3" nails all the


Hi foxden503,

Welcome to fixya!

As a general rule, framing nailers use anywhere from 45 to 120 psi to drive nails. But this also depends on the hardness of the wood.
The nail head should be flush with the surface. If it sticks above the wood, increase the pressure a little bit at a time until you achieve this goal.

Hope this helps. If it does, I'd appreciate your vote. Thanks,

Adjusting airpresure


There is nothing on a nailer to adjust the air pressure. You have to do it at the pressure regulator. It is feasable to mount a regulator at the gun but more likely it's on the compressor. Most nail guns are rated for 90 to 120 psi. Set your regulator to hold the hose pressure between 90 and 100 psi. Using higher pressure to set the nail will ruin your nailer. Use the depth adjustment on the gun to set how far the nail is driven.

GUN NOT SETTING NAILS


Hello jsc.... the depth that the nailer drives the nail is dependent upon two factors, the hardness of the material you are driving the nail into and the air pressure. Generally when you want the nail to go in more you adjust the air pressure to a higher setting, going 5 psi at a time until you are close to perfect and then fine tuning the air pressure.

Sometimes people find that the air compressor itself is inadequate for the job. in that case, the only choice is to move up to a higher psi compressor. Joe

Thanks for choosing Fixya!

Porter Cable BN125A won't set nails below surface


Not sure about the seal, but I do know the pressure has to stay up for this nailer to be effective. Try oiling the gun to free up the mechanics and don't use old nails.

The nails aren't going in far enough using a air cleat nailer


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.
