    Why won't my Central Pneumatic Nail Gun drive nails all the way?
    • N
      Nicole MercadoAug 14, 2025
      If your Central Pneumatic Nail Gun isn't driving nails in completely, it could be due to a few reasons. First, the Drive Pin (46) may be rounded and slipping off the nail. Replace it. Second, ensure you're supplying the correct air pressure (55-95 PSI). Finally, check the Compression Spring (6) for broken coils or reduced length and make sure the Exhaust (1) is clear.
