Anxious, having no time to get Chinese manual (1,5)
I believe the answer is:
i ching
'chinese manual' is the definition.
(ancient Chinese text)
'anxious having no time' is the wordplay.
'anxious' becomes 'itching'.
'having no' is a deletion indicator.
'time' becomes 't' (abbreviation).
'itching' with 't' taken away is 'I CHING'.
'to get' is the link.
(Other definitions for i ching that I've seen before include "Ancient text" , "text from China" , "Ancient Chinese manual of divination (the Book of Changes)" , "Bk. of Changes (Chin.)" , "Chinese book of wisdom" .)
