Assuming there is no air leaking from the gun, the check seal (part #175520) causes piston to retract. It is a band that fits around the cylinder and covers vent holes in cylinder. You can use orings in place of band (or be creative). Other reasons for piston not returning to top include bent driver, worn piston oring, or cylinder/ oring lacking oil. Good luck

Hi I am having problems with my porter cable air nailer.. 2" brad nailer.. The hammer is not retracting far enough to hit the next nail.. I have taken it all apart and cleaned it and re oiled it but...

This is usually a sign that the hammer is slightly bent or the o-ring seal is going bad. You have to replace the hammer. If replacing the hammer doesn't work, the barrel it rides in is out of round and will need replaced. These pull out hard and you need allot of grease and patience to get them back in square to keep the seals intact.

Driver pin on model FN250A not retracting far enough to drive next nail. Will shoot 2 or 3 nails and miss 6 or so.

I had the same problem with an electric stapler from Craftsman after years of disuse. The solenoid that powers the hammer that is no retracting may require lubing if this is possible.

If not, then if the product is within warranty, you might be able to get a replacement.

Hammer does not retract completely

Usual cause is lack of lubrication. Try really loading the air tool oil into it and pushing hammer back. Cycle it a few times and keep it oiled.

Put about 10 drops of oil a day with heavy use.

Also look if there is a broken nail in the works and clear any jams.

Plunger want retract

The hammer could just need to be oiled or you could have blown a seal in the gun which is not expensive to fix around 20.00 . A lot of times when my gun jams on a nail it gets stuck so the hammer won't go down. I just use something thin that will fit on the hammer and take a hammer and just tap it back into place.
