Hi Ron, Thank you for your question. If the driver on your nail gun will not return, you will need to check the o-rings, the bumper, the seals and the gaskets, the driver, the piston ring, the springs, the piston head valve and the trigger valve. Once you have determined the part you need, please feel free to call customer service. We are open 7 days a week and anyone will be happy to assist you. We look forward to hearing from you!
