Gasboy 61 / 61 pump vanes

[cosmo99]

Does anyone have a picture of the correct way to put the vanes in the pump? I read the instructions but it's still not clear to me which way the sloped edge of the vane should face.

No picture but the tapered (slope) part of the vanes face the outer inner diameter of the pump cylinder and that applies to air operated rotary tools as well.
