Sand has entered my CP734 impact wrench.

Check the following website. It is a pdf file, so you will need Acrobat Reader, which is available on this website. After it loads, it lists various CP model numbers on the left side, so scroll down to 734 and click on it( it says 734 OBS) and it will open an exploded view of the breakdown of the CP 734 impact wrench. On the Acrobat toolbar, you can expand the picture as much as you want to and print it.

Good Luck!
