I mua i te werohanga, tirohia te pūmautanga o te hau o ngā werohanga me ngā ngongo rapa, whakakapia ngā gasket rapa tawhito, ngā piston me ngā ngongo rapa i te wā tika, ā, whakakapia ngā ngongo karāhe kua roa e whakamahia ana hei ārai i te rerenga wai.
I mua i te werohanga, hei whakakore i te haunga o te ngira, ka taea te pana i te ngira ki runga ki te nohoanga o muri (kaua e werohia te rongoā wai, ka waiho hei para) hei whakakore i te hau, ka taea rānei te whakauru i te ngira ki roto i te pounamu rongoā wai, ka pana tonu kia kore ra ano he hau.i roto i te ngira.
I te wā e werohia ana, whakamahia te kaha tika hei ārai i te pēhitanga o te rongoā wai ki muri o te piston. I taua wā anō, kaua e tere rawa kia kore ai e werohia te rongoā wai me te kore e mimitia ki roto i te ngongo karāhe, ka hua ake he horopeta hē, ka whara hoki te mea e werohia ana.
I roto i te mahi whakatipu poaka, ki te whakatakotoria te waha o te pounamu ki raro, whakamahia te ngira whakaputa hau hei ārai i te turuturu o te taupoki o te pounamu. Kaua hoki e taea te whakaputa hau, pēhia te mono ki te taha i ia wā, kia uru mai te hau, kia nui ake ai te pēhanga i roto i te pounamu.
Mēnā ka puta he hapa, ka taea e koe te whakatika i runga i te āhuatanga tūturu, te whakatika, te whakakapi rānei i te wāhanga.
