Nā Kūlana Hoʻouna
Ma muli o nā kūlana hoʻopuka a me ka pae PSL, hiki ke hoʻokaʻawale ʻia e like me kēia:
PSL1: X42 a i ʻole L290;

ʻAe ʻo X42 i kēia hana hana:
Inā ʻike ʻoe i kēia mau pōkole paʻakikī e hoʻomaopopo, e nānā i kā mākou hui ʻana o nā ʻatikala manā pōkole maʻamau no nā paipu kila.
Hiki iā Botop Steel ke hāʻawi iā ʻoe i ka nui o ka nui o ka paipu e like me ka mea i hōʻike ʻia ma ka papa ma lalo nei.
