Ngā Tikanga Tukunga
I runga i ngā tikanga tuku me te taumata PSL, ka taea te whakarōpū i te X60 penei:
PSL1: x60, L415 rānei;
PSL2: X60N, X60Q, X60M, L415N rānei, L415Q, L415M rānei.
N: E tohu ana i te whakatikatika o te rauemi. Mā te whakamahana i te maitai ki tētahi pāmahana, ā, muri iho ka whakamataohia e te hau. Hei whakapai ake i te hanganga moroiti me ngā āhuatanga hangarau o te maitai, hei whakanui ake hoki i tōna pakari me tōna ōritetanga.
QKo te tikanga o tēnei ko te whakamātao me te whakamahana. Te whakamahana i te maitai mā te whakamahana ki tētahi pāmahana, te whakamatao tere, kātahi ka whakamahana anō ki tētahi pāmahana iti iho. Hei whiwhi i te taurite o ngā āhuatanga miihini motuhake, pērā i te kaha me te pakari teitei.
M: E tohu ana i te maimoatanga wera-mīhini. He huinga o te maimoatanga wera me te miihini hei whakapai ake i te hanganga moroiti me ngā āhuatanga o te maitai. Ka taea te whakanui ake i te kaha me te pakari o te maitai me te pupuri tonu i ngā āhuatanga whakarewa pai.

Ngā Painga o te SAWL (LSAW)
Mena kei te hiahia koe i tētahi paipa maitai matotoru me te whānui nui, ko te kōwhiringa tuatahi koSAWL (LSAW) paipa maitai. Ka taea te whakaputa i ngā paipa maitai LSAW i ngā rahi tae atu ki te 1500mm te whānui me te 80mm te matotoru o te pakitara, e tino kaha ana ki te whakatutuki i ngā hiahia o ngā paipa tawhiti mō ngā kaupapa nui.
Hei tāpiritanga, i te wā o te tukanga whakaputa, ka whakamahia e te paipa maitai LSAW te whakarewa pewa rua-taha i raro i te wai (DSAW) tukanga, e whakapūmau ana i te kounga o te hononga whakarewa.
Hanganga Matū API 5L X60
