ROOFING COIL GUN

[ALEX]

My gun keeps getting stuck with the piston in the out position. It doesn't go back in? What do I need to do to repair it?

Hi Alex,

I suspect that the faulty part in your nailer is the check seal, Item #120. It is a large, rubber o-ring that acts as a valve on the cylinder. It is part #886119. If your gun has had quite a bit of use then I would consider installing an overhaul kit. The overhaul kit will replace all of the o-rings and gaskets as well as the bumper and the trigger valve. The overhaul kit is part #910463 and is available from http://www.ereplacementparts.com.

I hope this helps with your repair!
