'possibly chance it over line of mechanical products?' is the definition.
I can't judge whether this definition defines the answer.

'possibly chance it over line' is the wordplay.
'possibly' indicates an anagram.
'over' means one lot of letters go next to another (in a down clue, some letters go over others).
'line' becomes 'l' (used when specifying particular lines from a poem).
'chance'+'it'='chanceit'
'chanceit' is an anagram of 'technica'.
'technica'+'l'='TECHNICAL'
