Robert - For model number FN250C

Not working getting good air psi trigger works push a board and just air
Chris Boyle Profile
Hello Robert, thank you for contacting us. According to our research, the O-ring has likely dried out or cracked, causing it to lose its airtight seal against the cylinder wall. This prevents the tool from building enough pressure to shove the driver blade down, letting air blow past the piston and out the exhaust instead. You may need to replace it. The part number is PS10183608. We hope this sorts out your problem!
