Whakaahuatanga poto:

Ko te anga o te miihini piko hiko ka tukatukahia i muri i te tarai ki te whakarite kia kaha te kaha, te tino rangatiratanga me te nui. Kua whakauruhia te punaha tukutahi, a, ko nga taha e rua o te riipene e nekehia ana i te wa e rite ana ki te tohu tukutahi. Ko te taputapu me te taputapu utu whakahekenga o runga, me te taputapu taapiri teitei o runga. Ko te reanga o te miihini o te miihini puhoi he tino whakatikatika, a ko te whakatikatika te hiko hiko me te whakatikatika pai, me te mahi ngawari. Ko te kaakahu X-toxis hoki ka peia e Siemens Motor, ka peia e te kaawhiawhi i te porowhita-a-ringa, na te whiu o te miihini y-tuaka e whakahaerehia ana e Siemens Motor hei whakarite kia pai te whakatau. Ko te punaha whakahaere a te E21 e whiri ana i te punaha whai hua ki te whakahaere i te mahi x-tuaka me te Y-tuaka hei whakarite kia tika te tika.
