Me tere te whakamahi i ngā paparanga onepū engari kaua e kaha rawa te kaha.Wiri toka hau S250he taurite tino pai — he tere te urunga me te kore e wiri koretake. Ka whai hua ngā tīma hanga i te kounga pūmau o te poka, te maeneene o ngā huringa pupuhi, me te pai ake o te tirohanga nā te whakaiti i te pupuhi puehu.

Mai i te papa o tō mātou wheketere ki te mata o te toka, he mea hanga te S250 mō te māmā me te manawanui. Ka hono tika ki ngā raina tuku hau paerewa (pēhanga e taunakitia ana: 0.4–0.63 MPa). Ka tīmata ngā kaiwhakahaere mā te whakau i te taputapu, te whakarite i te maitai keri, me te whakatuwhera i te takirere hau. Ka ngāwari te whakarite i te waewae mō ngā kōhao koki, poutū rānei, i te mea ka pupuri te wai horoi i te mata kia matao, kia horoia hoki ngā tapahi i te wā tonu. Ko te paninga hinu auau o te chuck me te tirotiro i ngā hiri piston i ia wā koia anake te mea e hiahiatia ana hei pupuri i te mahi tino pai o ngā nekehanga i muri i ngā nekehanga.

I mua i te whakaurunga o te S250, he maha ngā kaupapa rori onepū i raru i ngā tere whakamua kāore i te ōrite. He maha ngā wā ka pakaru te toka i ngā taputapu keri nui rawa te kaha, ka pakaru te toka, ka kore e pumau te āhua. Ahakoa he ngawari ake ētahi atu tauira, he puhoi rawa, ka roa te pupuhi me te kore e mahi a ngā kaimahi. Mai i te hurihanga ki te S250, e whakaatu ana ngā kaiwhakahaere o te papa i tētahi panonitanga kitea. Kua piki ake te tapeke o ngā keri o ia rā mā te toharite o te 18–22%, nā te auau pānga kua arotauhia o te taputapu me te tango tere i ngā maramara. I heke te whakamahinga o te maitai keri nā te mea i karohia e te mahi a te mīhini te kawenga taha. Ko te mea tino kitea pea, i pai ake te taiao mahi: he iti ake te puehu rererangi me te iti o te "haruru" i taea ai e ngā kaiwhakahaere te whakanoho tika ake i ngā poka me te tere ake o te whakaoti i ngā matā.

Hei kaihanga motuhake mō ngā taputapu keri toka, ka arotahi mātou ki te hanga mīhini pakari, e rite ana ki ngā mahi. Ko tā mātou tukanga whakaputa—mai i te hanga whare ki te huihui i ngā takirere—ka whakahaerehia i roto i te whare, e āhei ai mātou ki te whakarite i ngā taputapu pēnei i teS250mō ngā hanganga motuhake. Mā tēnei huarahi whakatapua ka whakarite kia pono te mahi a ia waeine ki ngā wāhi tino hira: i te mata, i raro i te kawenga tūturu, i ia rā, i ia rā.

E whakaatu ana te S250 kāore te keri onepū whai hua e pā ana ki te kaha mata; engari ko te whakawhiti i te nekehanga tika. Ka ine te pūnaha takirere o roto o te keri i te hau hei tuku i te raupapa tere o ngā pupuhi - ia mea he nui hei pakaru i te toka engari kua whakatikatikahia kia kore ai e moumou te kaha hei wiri. Ka puta tika tēnei ki ngā poka poka tika ake, ma ake me te iti ake o te pakaru o ngā taputapu pau. Mō ngā kaimahi kirimana, ko te tikanga he iti ake ngā keri anō, he pai ake te utu pahū, me te matapae i te nekehanga whakamua mō ia nekehanga.

He mea nui te tangata i te papaanga. Mā te iti o te hoki whakamuri me te māmā o te huinga waewae o te S250 ka taea e te kaiwhakahaere kotahi te whakahaere i te nekehanga me te kore e ngenge. Ka taea e te waewae o te motuka hau te toronga maeneene ahakoa i roto i ngā āhuatanga haukū, me te pupuri tonu i te pēhanga whāngai. Ka whakapotohia e ēnei taipitopito te ara ako mō ngā mema hou o te kapa, ā, ka āwhina i ngā kai keri tauhou ki te pupuri i te manawataki i roto i ngā rauna roa.

Hei whakarāpopototanga, ka hurihia e te keri toka hau S250 ngā wero motuhake o te kirikiri hei mahi noa. Ka whakakotahi i te tere me te whakahaere, te pakari me te ngāwari o te mahi, me ngā hua pumau me ngā āhuatanga mahi kua whakapaitia. Mō ngā tīma e akiaki ana i te whanaketanga rori i roto i te toka ngohengohe ki te toka waenga, he taahiraa whakamua kitea tēnei i roto i te hua o ia rā me te matapae kaupapa.
