Taura whāngai Hansen 78 te ngaronga iti
Tau Tauira: Taura Whāngai RF
Ngā Āhuatanga Hanga:
He nui te huka ā-tinana, he rīpene parahi i hangaia, i whakarewaina, i whakakoitia hei hanga i te ara iahiko o waho.
Kaiārahi o roto: Ngongo Parahi Maeneene/ Konumohe Paninga Parahi/ Ngongo Parahi Hīriki
Hikohiko: Polyethylene Huka Tinana (PE)
Kaiārahi o Waho: Ngongo Parahi Kopikopiko/ Ngongo Parahi Koki/ Ngongo Parahi Hīriki
Koti: Pango PE, iti te paowa, ātete ahi kore-halogen rānei
Ngā Painga:
He iti te whakaiti, he iti te tū o ngā ngaru, he teitei te parepare, he ātete ki te haukū, he ngāwari, he kaha teitei ki te ārai i te kume.
Awhe Taupānga:
Te pāho me te pouaka whakaata, te whakawhitiwhiti kōrero i roto i te ngaruiti, te whakamahinga hōia, te rererangi, te kaipuke, me ētahi atu āhuatanga e hiahiatia ai te taura RF.

Tohutoro Tākai
Ngā Tohutohu Tāutanga o te taura tino ngāwari N, 7/16, 4310 rānei 1/2″
Hanganga o te hononga: (Pikitia 1)
A. nati o mua
B. nati tuara
C. te pēke
Ko ngā inenga o te tango i te hua e whakaaturia ana i te hoahoa (Pikitia 2), me aro atu ki te tango i te hua:
1. Me whakakopa te mata pito o te ara iahiko o roto.
2. Tangohia ngā poke pērā i te unahi parahi me ngā kohao i te mata o te taura.
Te whakakotahi i te wāhanga hiri: Whakapirihia te wāhanga hiri ki roto i te ara iahiko o waho o te taura e whakaaturia ana i te hoahoa (Pikitia 3).
Te whakakotahi i te nati o muri (Pikitia 3).
Honoa te nati o mua me te nati o muri mā te whakawiri kia rite ki te whakaaturanga o te hoahoa (Pikitia (5))
1. I mua i te whakawiri, pania he paparanga hinu whakahinuhinu ki runga i te mowhiti-o.
2. Puritia te nati o muri me te taura kia kaua e nekeneke. Whakawirihia te tinana anga matua ki te tinana anga o muri. Whakawirihia te tinana anga matua o te tinana anga o muri mā te whakamahi i te kī makimaki. Kua oti te huihui.
