da250a nailer

[earl]

My nailer doesn't return the driver after firing. Will a simple overhaul fix this problem?

Hi earl,

There is a large o-ring in the gun that acts like a valve. It is typically what will cause the driver to not return. The ring is called the Cylinder Check Seal and is part #883926.

You might consider installing an overhaul kit. It will replace all of the o-rings, the bumper, and the trigger valve. It would also solve your driver problem. The overhaul kit is part #60073.

I hope this helps you get your finish nailer working again!
