may be gummed up try spraying with a carburetor cleaner and let it soak than spray with a penetrating oil and try a couple of nails sometimes the gun gets gummed up by the plastic or glue holding the nails together if it still is stuck possible slight burr or bend in rod

SOURCE: how do you clear jammed nails?

you gotta get rough with it. The inside of these guns are are real durable. Be sure to unplug the air hose first!!! take out all the nails and leave loading spring to the rear. If it will not lock tp the rear, figure out how to rig it so it will temporarly. Try using a screwdriver or a nail punch to push the driver of the gun back up. your gonna have to hit it with a hammer. When this is done, use some needle nose pliers to pull out the nails. If this does not work then you will have to break out the allen key set, and pull the nose off, not a big deal but pay attention to how it comes apart. this should be all there is to it.

Worn trigger and or worn firing valve. Remove the trigger and look for wear on contact surfaces (worn pin that holds trigger, worn inner lever inside trigger, worn or loose firing pin in valve ). Easy test for worn trigger. Remove the nails, remove trigger, fire the gun against wood with finger to test for proper action. If it works better without trigger, consider replacing trigger with new (I would also order the oring repair kit that includes the firing valve )
