1. He nui te mahi maanu, kaore e pa ki te tai.
2. Nga tae kanapa, kia rite ki nga whakaritenga a te kaihoko ki te whakarato i nga momo tae.
3. Ki te whakatauritea ki te kaitao karekau, karekau te tikanga whakamahi ki te taapiri hau, kaua e mataku ki te rakuraku, kaua e mataku ki te werohanga, kaua e mataku ki te waku, te aukati wai o te moana, te aukati waikawa me te alkali;Ko te roa o te oranga o te ratonga ki te 25--30 tau, me te noho haumaru me te kore tiaki.
4. Ahakoa he matua totoka, engari he tino marama te taumaha, he watea te whakaurunga me te ngawari o te waea.
5. A, no te te deformation kōpeketanga ko 60%, ka kitea te kaha tauhohenga mai i te iti ki te nui, a he tino tiketike te absorption pūngao.
