Questions & Answers

I just removed all seals and replaced them, checked all parts everything looks good, got it back together and still don't fire, what could be the problem ?
Tony for model number FN250C 16ga asked on 2019-09-11
Hello Tony and thank you for writing. We recommend checking your trigger valve assembly. We have this part for your model as part number 647620-00. Hope this helps!
Gun quit firing. Inspected cylinder and piston. Saw no issues. When I pull trigger, it hisses air but will not fire. Trigger issue?
Dennis for model number FN250C asked on 2019-10-06
Hi Dennis, if it is hissing air it sounds like it may be a faulty seal/ring part number 647950-00 or 647951-00 is likely. You would have to inspect the seals to determine which one is faulty. Thank you for your question and good luck with your repair!
FN250C driver will not return. Do I need a Driver replacement Kit or is there another solution?
John for model number FN250C asked on 2019-10-14
Hello John and thanks for writing. The driver not returning to the top of the cylinder is caused by several issues. Bent driver, piston o ring, and check valve. Remove the head and pull out the driver. Usually, the following parts might be damaged when we see that symptom: Seal # 647950-00 Piston driver assembly # 647649-00-K O ring # 647951-00 Trigger valve assembly # 647620-00 Grommet # 391814-00 Good Luck with your repair.
Originally, when I connected the air hose, the driver shot forward and would not retract. I later turned down the depth of drive adjustment, and manually pushed back the driver. When I connected the air hose again, it continually hissed out of the exhaust port.

how to replace triger valve I FN250C nailer
LeRoy for model number FN250C asked on 2020-02-21
Hi LeRoy, Thank you for your question. To replace the trigger valve, you will need a small hammer and a punch pin. First, remove the trigger pin with a punch pin. Then remove the trigger. Next, remove the pins and the valve assembly. Clean the area and it is also recommended to lubricate the o-ring. Then replace the valve assembly and trigger. We hope this helps. Thank you and have a great day.

are dimensions available?
WJA
Hello 1159621,

If we had a 649695-00 seal in stock. I would give you the dimensions on it. If you need that part for your nail gun and it is one of the two listed below. You can order it. If the two models listed below are not your model number. Do a model search @ ereplacementparts.com. And you should be able to locate the correct part you need.
