Gun is only a year old. followed all the maintenance procedures in the manual. never stored in the cold. always well-oiled. cleaned frequently. i loved the way this gun performed but i cussed the air blue today when this happened. if hitachi doesn't remedy this as a manufacturer's defect they will get a bad reputation if i have anything to say about it.

Does the fan run and the light blink ont he nailer? I have one that I just bought. I put in the wrong type of nails and got one stuck. I had to take the front apart to clear it and now the damm thing wont fire. The green light blinks and the gas cartridge is basically full, even the fan does run after I release the push lever, but no fire???
I wonder if yours is the same as mine did fire for a couple nails first just fine then got jammed...
I will try to charge the battery more.... MAybe like yours it needs a strong charge for the spark...

Oil leaking out of the nailer anywhere is just an indication that too much oil is being introduced. A good solution would be to reduce the amount of drops until no more leaks out or use an in line oiler at the gun. An oiler costs under ten dollars and feeds in oil vapor as you use air. Store / hang your nailer with the air inlet down at night to drain out access oil. Do not worry too much about the leaking though, I think that a bit too much oil is better than a lack of oil. Good luck.

Over time debris enters the gun and scratches the metal and plastic surfaces where orings seal against. These scratches will allow air to leak past. Remove the head and pull out the head valve. Examine the metal surface with magnify glass where the headvalve oring makes contact. Remove scratches with 400 grit paper. The surface must be smooth and the oring must seal snugly. Apply silicone paste lube on all surfaces and orings (available at Lowes in the plumbing department and swimming pool supply). Also check for scratches around the body of the gun were the cylinder plate is installed around the cylinder. The gun will not work properly will small air leaks. Remove nails and listen for leaks thru the nose of the gun. Repair as needed. Good luck with your gun.

New user will jam the gun/ nails because gun was most likely not bump fired. Placing the gun then depressing trigger will usually cause double fire in the hands of new user. New user should practice on scrap lumber bump firing at many angles till they get the idea; or give them a training period with a nailer that has a single shot trigger (they may develop bad habits with single shot however).
