Question about Hitachi NR90AD 3 - 1/2'' Clipped Head Strip Nailer
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.
