Hurry to clinch set point, perhaps (4,2,2)
I believe the answer is:
step on it
'hurry' is the definition.
(I've seen this before)
'set point perhaps' is the wordplay.
'perhaps' is an anagram indicator.
'set'+'point'='setpoint'
'setpoint' is an anagram of 'STEP ON IT'.
'to clinch' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for step on it that I've seen before include "Informally, hurry or drive faster" , "to flatten an insect?" , "Hurry up, put foot down on pedal" , "be quicker" , "Hurry! - set point (anag)" .)
