learning center question

[pezadoodle]

i am going through the lessons and am looking at the part about knife point cutting - http://blackcatus.com/learn/?page_id=231 - it says at the top of the page

The machine has been positioned head on so that the user can interpret the images as shown on the screen. We recommend you do the same.

and on the page before it - the machine has been positioned to the left - what exactly does this mean????

Head on means you are facing the front of your machine. To the left means you are facing the right side of your machine. The pictures on the two pages should show the difference as well.
