Mata parau, Ngā wāhanga mīhini ahuwhenua, Mata harore kōpae
Ko te maripi whakaora, e mōhiotia ana ko te maripi whakawātea ngahere, te maripi tapahi whakamakuku, te hoe whakaora rānei, he taputapu ngaio e whakamahia ana mō te ngaki i te whenua koraha tawhito, te whakawātea i ngā rakau iti, te tapahi i ngā pakiaka kākaho, me te tiaki ngahere. He mea hanga motuhake tēnei hua mō ngā kaitapahi paraihe kaha-teitei, ngā mīhini ngaki moroiti, me ngā mīhini whakaora whenua iti, ko te whāinga he whakaoti i ngā uauatanga o ngā taputapu tapahi tuku iho e ngāwari ana ki te whati me te pakaru ina pa ana ki ngā rakau pakeke me ngā pakiaka taru.
Ka whakamahia e mātou te maitai konupora waro-teitei 65Mn, te maitai puna rānei, hei hanga i te whakatakotoranga. Whai muri i te tukanga whakamahana o te tinei me te whakamahana, ka eke te pakeke o te mata tapahi ki te HRC 48-52, e kore e whakarite noa i te pakeketanga teitei o te mata tapahi hei tapahi ki te kakau rakau, engari ka mau tonu te pakari o te mata, ka taea ai e ia te "whakamarumaru" i te mata ina tūtaki ki ngā toka, ki ngā mea pakeke rānei, ā, ka ārai i te pakaru. Ka pania te mata o te mata ki te ārai waikura hiko, ki te paninga kore-piri PTFE rānei, he kaha te ātete ki te waikura, ā, ka taea te ārai i te piri o te oneone me te tarutaru, ka whakaiti i te mahi.
Hoahoa mata koi: He hoahoa mata niho maha, he mata piko rānei te mata, e whakauru ana i ngā mahi kani, tapahi, tapatapahi, me te wāwāhi. Ka taea te whakamahi i te pito koi o mua hei wawahi me te wetewete i te oneone, ko ngā mata koi ia ka taea te tapahi tere i ngā rākau me ngā aka rerekē he iti iho i te 5 henimita te whānui.
Te whakapai ake i te hanganga miihini: Ka matotoru te mata ki te 3.0mm-5.0mm (i runga i te tauira), he matotoru te tuaiwi, ā, kua hoahoatia te pokapū o te taumaha ki mua, mā te whakamahi i te inertia hurihuri hei whakaputa i te kaha tapahi kaha, ahakoa ngā pakiaka kākaho matotoru, ngā pakiaka pāma rānei ka taea te kuru ngāwari.
Tūnga poka hononga whānui: te whakamahi i te hoahoa poka pokapū paerewa me te whakanoho i te hoahoa poka titi, e hototahi ana ki te rakau putanga o te nuinga o ngā tauira mana pēnei i a Honda me Briggs & Stratton i te mākete, he ngāwari ki te tāuta, he pumau, ā, kāore e wiri.
Te whakaora i te koraha: Te whakawātea i ngā taru me ngā rakau iti hei whakarite mō te mahi ahuwhenua.
Te manaaki ngahere: Te tango i ngā paru i ngā ngahere taitamariki me te tapahi i ngā aka e mau ana i ngā rākau.
Te whakahaere i ngā māra hua rākau: Te tapahi i ngā hua whakawairakau matomato, te kuru me te whakahoki ki te mara.
Te hanga repo me te ara rerenga ahi: Te horoi whai hua i ngā otaota kua whanake ngā pūnaha pakiaka pērā i te wiwi me te tarutaru.
