Assembling A Hilti DX 350/ Ramset Cobra .27 Caliber 10 Shot Semi Automatic Tool 

Look at the trigger for any crack that might cause it to bend under pressure.

I don't disagree with that but I operate on the cheap and don't have the best equipment. I hadn't intended to do any videos like this but it was suggested that I do them without extra content, making it has short as possible. The person who suggested it has commented that he had looked for service videos before and they always seem to have more information than needed. I believe the proper quote was"Just tell me how to do it not why I need to do it." Anyway, I guess I can try to add other videos that are more detailed.

I understand your friends comment, some people do like to drone on and on. I have two DX 350's, both were caught in a recent flood here and were submerged for a day or so. I have them all cleaned up but there is something wrong with the trigger mechanisms. Your video is the only one here that goes into dismantling a DX350. I have a definite skillset when it comes to mechanical things but whenever internal springs are involved I lose my advantage. Thanks for responding and the video. It did give me some insight.

I have an idea that might work out just give me some time.

A more detailed video has been posted. Link in the description box.

Not that I know of but from the outside it looks to be of the same design as the DX-350, just upgraded into a new skin.

I'm not sure if I understand but apparently you are having an issue with the pin going into concrete. I suggest checking the piston ring for damage and also make sure you are pulling the barrel out all the way. this rests the piston for the next shot.
