When using nailer w/ compressor, nail goes in only 1/2''

Using staples with nailer for hardwood...with a compressor, when I use the nailer, the staple does not go into the the hardwood completely...goes in just about half an inch...could it be the compressor?

    I had a similar issue. On my nailer there is a dial that determines the depth to shoot the nail. If you have a dial, turn it or look at the manufacturer's website to determine if you have the ability to adjust the depth. If not, you may need to buy a nailgun that has depth control. It is very doubtful that you have a problem with the air pressure in the compressor.

I worked at a tool rental center while attending college and had the opportunity to learn a great deal about nailers /staplers. At the tool rental center we had a large variety of staplers available to the customer depending of the job. Not knowing what specific brand or model I will give you some things to check. You could have a broken tip on the driver, to check try nailing into soft wood to see if staple is driven well into wood. If not open gun and check for broken or bent driver blade and replace as necessary. If staple is driven into soft wood ok, then check that the driver piston oring/split ring fits snugly in cylinder. If the piston fits too loose in cylinder you will loose power. If piston fits snuggly in cylinder, then time to check air supply. We would use a tee fitting with male fitting , pressure gauge and quick connect at the end of the hose to check that the air pressure at the end of the hose is at rated pressure. With tee fitting installed, you can fire the nailer and check that the pressure is actually the same as the reading at the pressure control. You may discover that the pressure is too low at the hose end. Sometimes the pressure regulator will not allow the recommended volume of air to flow thru to the gun. The gauge at the end of the hose will show that the pressure will be somewhat slow to recover. The pressure should be set to 120 at the compressor and maybe drop to no less than 100 at the hose end. If you suspect that the regulator is causing problem, you may temporarily remove it and use air directly out of the tank if your pressure switch shuts off the pump at 125psi. Good Luck, hope this helps enjoy.

Only thing besides trying diff psi's to get it perfect and different length staples/different heads on staples(nails) , maybe try staple gun. Keep trying every woods different, odd that it started half way through job.. odd.

Not sinking the flooring nail down far enough

The pressure from your compressor needs to be 100psi at least. If you have a small compressor it may not be maintaining that pressure between cutting-out and cutting-in. Also you need to give the plunger on the top of the gun a fairly solid hit with the mallot. If you are fixing into old hardwood you could try a little bit of lubrication on the tips of your staples, candle wax may even help and is not to messy.
Good luck

Bostitch nail gun number SB-21n1 is jammed and need manual to know how to unjam it or a solution online. Was using it in the staple mode and it jammed after about 5 staples. Was using bostitch staples.

Hello. Begin by disconnecting the air hose. That way you can not get hurt while removing the jam. Get a pair of needle nosed pliers and remove each of the jammed staples. They will pull out I assure you. Then Use a little WD-40 or compressor oil to lubricate the working mechanism at the firing head. IF you must loosen up the mechanism to remove all of the staple parts be sure to use the correct size allen wrench. I am providing link to a free manual for your gun in case you don't have one:

D Farley,
I repair these nailers all the time. Anytime the nail or staple is bending you have 2 causes. Either the stapler has a broken blade, the magazine is loose on the foot gate, or you are shooting into plywood over concrete. that is allowing the staple to hit the cement subfloor. Use 11 /2" staples on 3/4" wood floor over 3/4" plywood when over concrete.
