He rite te waahanga taputapu ki te JF-3E.Mo te rorohiko, e wha nga tirohanga;Tirohanga tuatahi, Tiro ora, Tiro hopu me te tirohanga Tautuhinga.
I te tirohanga tuatahi, ka whakaatuhia te tohu a Jeffoptics ki te taha maui.Ko te uara koki, me te uara ahotea i roto i te whakatakotoranga PSI/MPa e whakaatuhia ana ki runga, ka whakaatuhia te paatene mahi (Whakatika/Tautuhi pana me te paatene tau) kei te taha matau.
I te Tirohanga Ora, kei te taha maui te ahua ora me te rangatira hurihuri.Ko te uara Koki, me te uara ahotea i roto i te whakatakotoranga PSI/MPa ka whakaatuhia ki runga, ka whakaatuhia te paatene mahi (Naianei ko te paatene "Hopu" me te paatene tau) kei te taha matau.Ko te koki hurihanga o te ruri ka whakaatuhia ki te taha maui o runga.
I te tirohanga kapohia, ka whakaatuhia ki te taha maui te whakaahua kua mau me te rangatira hurihuri.
I roto i te Tirohanga Tautuhi, Tau Rangatū, Uara Kaha, tauwehe 1 me te tauwehe 2 ka whakatauhia e te kaiwhakahaere.
