Sounds like your safety mechanism has fouled or slipped.I've had my bostich nailer for several yrs and it's always worked fine .... until this afternoon. About 30% of the time its double shooting nails. Any ideas as to why?
If it is set on auto and it bounces while your finger is still on the trigger it will shoot again.I doubt it's the nails, while I did switch brands of nails that box is close to empty. I'm helping a friend build an addition on his mobile home. When we get the framing done I'll bring it home and give it a good cleaning and going over. I'm pretty sure it has the automatic feature but I've never used it - sounds like a good place to start.
I assume this person already had the single hit (technically called "sequential trip") trigger, because they said it "worked fine," until recently, when it started double kissing. I've had a similar problem recently. Did yours come with the bump (technically called "contact trip") trigger already installed? Mine didn't, and still doesn't.Mark it should be shooting 28 degree wire welded nails. Double kissing means you may have the wrong trigger installed. I always remove the bump trigger and install the single hit trigger.
