You broke the "hammer" you can open the housing and replace it, fairly simply. You can buy replacement parts at most large scale hardware or tool stores. The task takes about 10 min, and some simple hand tools.

Remove nails and use thin tool to push driver all the way up to top of cylinder. If the gun fires one nail then skips, the driver is not returning to top of cylinder. If no nails fire, then nails are not feeding into proper position. Driver must return to top to allow nails to feed into position. Most common problems are bent driver, worn piston oring and bad batch of nails(head too large). Good luck

May just be a stuck headvalve or safety is not pushing trigger pin all the way into trigger valve. If trigger pin is being pushed up all the way into valve, check headvalve. Remove head and try to press in headvalve with thumbs. If it feels stuck, apply air pressure to vent hole on gasket surface to pop it out. Apply silicone paste lube to surface and orings. Re-install and check. If head valve was not stock, lube and replace head.

Check and adjust the air pressure at the compressor. All air tools have a recommended range of pressure, and you may not have enough air for the tool to work. Also, place two drops of pneumatic oil or light machine oil into the air inlet at the nailer, and then connect the hose. Fire the gun several times into scrap wood. Oil with 2 drops daily.
Best regards, --W/D--

Make sure no nails in gun. With air connected listen for leaking thru nose of the gun also. If leaking thru nose slightly, air is getting past the cylinder seal oring and/or top of cyl is not seating against headvalve. Repair leak to nose of gun before trying to fix head leak. With no air leaking thru nose of gun, add plenty of white grease to orings in the head (one oring at a time) to see if leak is less and/or grease will streak behind the leaking oring. Then repair as needed. May need slightly thicker oring or sand surface where oring makes contact to remove scratches that are allowing air to pass. Also air can enter the head thru the small port in the gasket leading to the head (make sure that the gasket is sealing).
