How to identify action verbs as linking verbs?

Dear Student,

Your question does not seem to be correct. Action verbs do not function as linking verbs.
An action verb is a verb that describes an action. They tell us someone or something is doing.
Eg: He hits the ball. Here, 'hits' is an action verb.
A linking verb simply connects the subject with the rest of the sentence. 
Eg: He is a cricketer. Here, 'is' a linking verb.

So, please check your question and be a little specific so that we can provide you with some meaningful help. 

Regards,
