Hand-operated guide (6)
I believe the answer is:
manual
I believe this clue is a double definition.
'hand-operated' is the first definition.
(similar in meaning)
'guide' is the second definition.
(I've seen this in another clue)
(Other definitions for manual that I've seen before include "Guide" , "Book of instructions" , "Physical hard work" , "Work-book" , "Book; done by hand" .)
