Looks like my air/nail gun stopped working

I recently bought a Mastercraft used nail gun from marketplace, which is normally used for baseboards. For reference images are attached.

I was using it with my Air compressor and it was working all good, after nailing about 15 nails when i fire a nail it only gives a sound (like normally it does) but does not fire/hit the nail so nothing happens.

I was using it at 70 to 90psi presure which was recommended for this model, I checked nails were not finished but still I loaded bit more, I can't see any nail stuck in it, any idea what could be the reason?

Thanks

 

Check again where the nail comes out. There may be one or two nails jammed inside. They may not be visible from the outside. You can disassemble the nail head to check inside.

 

Open the nose piece and see if the driver blade is stuck out. If it is, shove it (and the piston) back up.

Put 2 or 3 drops of oil in the air port each day you use it.

 

Thanks, I will give it a try and get back to you guys.

 

When this happened to me it was a stuck nail. Hope it's also something easily fixable in your case.
