[bitwize]

This kind of phrasing is so common (in American English directions) that I remember examples from when I was very young:

(on toothpaste) "Squeeze tube from the bottom and flatten it as you go up."

(on a kerosene heater) "Rotate wick adjuster knob clockwise until it stops."

Australians tend to prefer more conversationally phrased directions from what I've seen, e.g., the rail station signs that read "Keep off the tracks and use the walkways provided to cross. Or catch a $100 fine. Don't say we didn't warn you, mate!"

Maybe it's a cultural thing.
