Continues surge one's set in motion (7,2)

I believe the answer is:

presses on

'continues' is the definition.
(I've seen this before)

'surge one's set in motion' is the wordplay.
'surge' becomes 'press' (surge can mean to press on).
'set in motion' indicates an anagram (letters made to move around).
'ones' with letters rearranged gives 'eson'.
'press'+'eson'='PRESSES ON'

(Another definition for presses on that I've seen is " Continues".)

I've seen this clue in The Guardian.
