  Examining the symmetries of the pseudo-action, we propose a prescription for
the new Feynman rules for the Ramond sector of the WZW-like heterotic string
field theory. The new rules are an analog of that recently proposed for the
open superstring field theory and respect all the gauge symmetries including
those provided we impose the constraint after transformation. It is shown that
the new rules reproduce the well-known on-shell tree-level amplitudes for four
and five external strings including fermions.
