Charlie for model number FN250A asked on 2023-01-17
Hello Charlie, Thank you for writing. We suggest checking the Driver for wear or damage. We offer a Driver Maintenance Kit to correct the issue if needed. We hope this helps!
eReplacementParts Team January 17, 2023
The drive pin will drive one nail then stays extended . It will retract on the next pull on the trigger then will drive another nail. I have replaced the trigger valve because it was leaking air in that area. No leak now but it won't retract the pin. Thanks

Hello Robert, Thank you for your inquiry. It could be the piston stop, the spring or one of the gaskets/o-rings. Check any of these parts for any visible damage or obstructions. Good luck with your repair.
