Eia kekahi mau mea nui e pili ana i nā paipu kila LSAW:
Kaʻina Hana Kuʻi: Hana ʻia nā paipu kila LSAW ma ka hoʻohana ʻana i kahi kaʻina hana kuʻi arc hoʻokahi, pālua, a ʻekolu paha i hoʻopaʻa ʻia. ʻAe kēia ʻano hana i nā kuʻi like a kiʻekiʻe ma ka lōʻihi o ka paipu.
ʻUmi Longitudinal: Hoʻokumu ke kaʻina hana kuʻihao i kahi ʻumi longitudinal i loko o ka paipu kila, e hopena ana i kahi kūkulu ikaika a paʻa hoʻi i kūpono no nā noi like ʻole.
Ka Mana Anawaena Nui: Ua ʻike ʻia nā paipu kila LSAW no ko lākou hiki ke hana ʻia i nā anawaena nui, e kūpono ai lākou no nā noi e pono ai ka lawe ʻana i nā nui o nā wai a i ʻole no ka hoʻohana ʻana i nā noi kūkulu.
Nā noi: Hoʻohana pinepine ʻia nā paipu kila LSAW i nā noi e like me nā paipu hoʻoili aila a me ke kinoea, piling, kākoʻo kūkulu i ke kūkulu ʻana, a me nā papahana ʻoihana a me nā ʻoihana ʻē aʻe.
Hoʻokō me nā Kūlana: Hoʻolālā ʻia a hana ʻia nā paipu kila LSAW e hoʻokō i nā kūlana ʻoihana a me nā kikoʻī, e hōʻoiaʻiʻo ana e hoʻokō lākou i nā koi no nā noi kikoʻī a me nā kūlana kaiapuni.
