The addition of 'will' would not be required in common usage,  But if 
you are putting this under the microscope in pursuit of clearer tech 
writing, then I think you might reasonably expect someone to misread 
your example as a badly written description of two unrelated events.

IMHO, the addition of 'will' would give the example symmetry, and that 
would more strongly imply a connection between the events.  But the 
addition of 'then' instead of will would establish the connection more 
clearly as a sequence.

What is the context of your question?  Are you studying English as a 
second language, or Composition 101, or ...?
