Ko ngā maina poka hohonu e hiahia ana ki ngā taputapu e mau tonu ana te kaha pānga ahakoa i raro i te pāmahana teitei me te haumākū.YT29A wiri toka hauhe tino pai i roto i ēnei taiao tino kino nā te hanganga piston pakari me te āwhina waewae-hau pumau.

 

Ina whakamahia mō te whakawhanui poutū o te toki, ka whakapotohia e te YT29A ngā huringa keri, ka whakarite kia rite te hohonu o te kōhao, ā, ka āwhina ki te pupuri i te mata tapahi kia ma. Ko te tikanga o tēnei he tere ake te pupuhi o ngā pere mete pai ake o te tango i te konganuku.

 

I runga i tēnei turanga pakari, ka whakauruhia e te YT29A ētahi auahatanga hoahoa e aro tika ana ki ngā wero tino uaua o te keri hohonu. Ko tētahi āhuatanga matua ko tana tikanga ārai-aukati matatau. I roto i ngā hanganga whenua uaua e rerekē ai ngā papa toka i roto i te rua kotahi, ka ngāwari te hopu i ngā keri tuku iho, ka puta he whakaroa utu nui me te kino pea. Ka whakahaere aunoa te pūnaha takirere taurite hihiri o te YT29A i te pēhanga hau ina tūtaki ki te ātete, ka taea ai e te mata te hiko i roto i te toka pakaru, i ngā whakaurunga ngohengohe rānei me te kore e whakaroa. Ehara i te mea ka tiakina noa te kounga o te maitai keri engari ka whakaitihia hoki te ngenge o te kaiwhakahaere, nā te mea he iti ake te hiahia mō te wawaotanga ā-ringa kaha i ngā wāhanga uaua.

 

Ko te pakari tētahi atu tūāpapa o te rapunga whakaaro hoahoa a te YT29A. Ko ngā wāhanga o roto, inā koa te piston me te chuck, he mea hanga mai i te maitai koranu kua whakapakeketia. I whiriwhiria tēnei rauemi kia ārai i te kakahu whakakoi i puta mai i ngā granite me ngā basalt he nui te ihirangi quartz, ka taea te whakangaro tere i ngā taputapu iti. Hei tāpiri, ka whakauruhia he pūnaha tātari puehu maha-wāhanga ki roto i te whakaurunga hau. He mea nui tēnei i roto i te hau makuku, taumaha-matūriki o te maina hohonu, ka taea e te paru me te makuku te hanga i te paru whakangaro i roto i te tikanga keri, ka tere ake te waikura me te kati pinepine i ngā mahi tiaki. Mā te whakarite kia tae noa te hau ma, maroke ki te rūma matua, ka roa ake te YT29A i ngā wā ratonga, me ngā pūrongo mara mai i ētahi mahi keri nui e tohu ana i te 40% te whakaiti i te wā kore i whakaritea mō ngā whakatikatika ki ngā tauira o mua.

 

Kāore e taea te whakanui i te pānga ergonomic o te YT29A ki te kapa keri maina. Nā tōna āhua mama, kiato, me te huinga kakau whakaiti wiri, ka whakaratohia he mana whakahaere pai me te ngāwari ki te nekeneke i roto i ngā wāhi kuiti. Ko te whare pumauwaewae-hauEhara i te mea ko te tautoko anake te mahi; engari ka hangaia he kaha ātete e mimiti ana i te nuinga o te whana whakamuri, kia taea ai e te kaiwhakahaere te pupuri i te tūranga tika mō ngā wā roa. Ko te hua o tēnei he tika ake, he tika ake te whakanoho i ngā kōhao pupuhi, he mea nui rawa atu tēnei mō te pakaru pai me te pumau o te pakitara. Ko te hua whakakotahi he taiao mahi haumaru ake, he whakahaere ake, me te whakapainga nui o te kounga o te rakau kua keria.

 

Hei whakamutunga, ehara te YT29A i te taputapu noa iho; he hoa mahi whakaputa i hangaia mō ngā āhuatanga tūturu o te keri hohonu o te ao hou. Mā te whakaoti i ngā take matua o te aukati, te kakahu, me te taumahatanga o te kaiwhakahaere, ka tukuna he taumata pono o te mahi e tere ake ai te wā o te kaupapa.Te mainaKa taea e ngā kaihangarau te matapae i ngā wāhanga keri me te tika me te māia ake, me te mōhio ka taea e te YT29A te pupuri i tana mahi whakatauranga i ia rā, i ia rā, me te pana i ngā rohe o ngā mea ka taea te whakatutuki i roto i te whai i ngā putunga kohuke hohonu rawa atu o te ao.
