- Move VERT and HORZ stage motors to reposition the low-Z sample box until the bellows is not bent vertically or horizontally. VERT is about 42, and HORZ is about 25, but check by eye and adjust if still bent.
- Look behind the back of the low-Z sample box. There is a rail along the back of the box attached to the stage plate. There are two allen hex bolts going through this rail to hold the back of the low-Z box to the rail. Use a 5/32" Allen wrench to loosen each bolt a few turns. This will allow the box to slide upstream and downstream on the stage.
- Remove the clamp for the O-ring between the two gas sections.
