If the gun does not fire, make sure that the safety foot is depressing the trigger valve all the way in when attempting to nail. Simple test is to remove the trigger exposing the firing pin. With nails removed and air connected, with quick motion depress the firing pin all the way in. If the gun fires make adjustments to safety foot. If the gun still does not fire (with headvalve lubed) replace the firing valve core part # ca0108. Good luck

If the trigger is set to single fire, you will need to place the gun against the work then pull trigger as you have done. Try setting the trigger to bump fire and try again.

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.

The condition of the driver oring is an indication of wear of all the other orings in the gun. Remove the nails and lightly tap the nose against piece of wood. If the driver drops to bottom of cylinder the oring is worn out and time for oring kit. Hitachi nailers are sensitive and will double fire if placing the foot against work then depressing trigger. Adjust the depth thumb screw several turns either direction then depress trigger and quickly bump gun against work. Good luck with your repair.

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.
