Ko te kani mekameka tētahi o ngā mīhini māra e whakamahia whānuitia ana, ā, ko te nuinga o ngā taputapu hiko e whakamahia ana. Nā te mea he koi rawa ōna niho, ā, e whakamahia ana mō te tapahi rakau tere-rahi, me tino kaha ake ngā mahi ārai haumaru. Ki te kore e whakahaerehia i te wā tika, ka puta he tūponotanga haumaru, me aro atu ngā kaiwhakamahi ki tēnā. Ko te rōpū tohunga hangarau Tiamana Steele, te kaihanga kani mekameka nui rawa atu o te ao, i whakarapopoto i tētahi raupapa o ngā pūkenga whakamahi me te tiaki i ngā kani mekameka me ngā take e tika ana kia arohia, hei whakapuaki ki ngā kaipānui.
● Me whakarite kia whakahinuhinuhia te mekameka kani
He mea nui te whakahinuhinu o te mekameka kani me te arataki mō te whakamahinga o te kani mekameka. I kī te tohunga hangarau, me maka te mekameka kani ki waho i te iti o te hinu whakahinuhinu, kaua e mahi i roto i te mekameka kani me te kore he whakahinuhinu. Ki te maroke te kani mekameka, ka tere te pakaru o te taputapu tapahi, ā, kāore e taea te whakatika. Nō reira, me tirotiro e tātou te nui o te hinu i roto i te tāke hinu whakahinuhinu me te mekameka i mua i te tīmatanga o te mahi.
Hei hanga i ngā kani mekameka me ngā kaiārahi kia whiwhi hinu whakahinuhinu aunoa me te pono, kounga teitei, iti te parahanga taiao, he pai te whakamahi i ngā kani mekameka me ngā kaiārahi hinu whakahinuhinu, pērā i te kaha o te hinu whakahinuhinu ārai-pakeketanga, ka tere te pirau. Ki te iti te kaha ārai-pakeketanga, ka ngāwari te hinu whakahinuhinu ki te kapia, ka hanga he matū pakari e uaua ana ki te tango, inā koa i roto i ngā wāhanga tuku mekameka kani, te mamau me te taha o te mekameka kani. He mea nui ina mau te papu. Hei tāpiri, kaua e whakamahi i te hinu whakahinuhinu para. Kāore i te hinu whakahinuhinu para te kaha whakahinuhinu e hiahiatia ana, ā, ki te maha tonu te pānga ki te hinu whakahinuhinu para ka mate pukupuku kiri, ka kino te taiao ki te hinu whakahinuhinu para.
I ia wā e tāpirihia ana te wahie ki te whakakī i te hinu whakahinuhinu mekameka, me whakarite kia pau te wahie, kia toe tonu te hinu whakahinuhinu i roto i te tāke hinu whakahinuhinu mekameka. Mēnā kāore e heke te nui o te hinu i roto i te tāke hinu whakahinuhinu, tera pea nā te aukati i te ara o te hinu whakahinuhinu. I tēnei wā, tirohia te whakahinuhinu mekameka kani, horoia te hinu, ā, mēnā e tika ana, me mahi ki te kaihoko mō te āwhina.
Mō ngā taputapu wheketere hou, kia kore ai e nui te kawenga, kāore e hiahiatia kia tere te noho i roto i te wā e oma ana, nō reira, i roto i ngā pouaka tuatahi e toru o te wahie e pau ana i mua i te paunga o te tere. Nā te mea me ako ngā wāhanga neke tetahi ki tetahi i roto i te wā e oma ana, nō reira i roto i tēnei wā poto, he nui ake te ātete waku o te rango. Tata ki te 5 ki te 15 te hinu miihini kua whakamahia i muri i te taenga ki tōna mana mōrahi. I te wā e mahi noa ana te kani mekameka, kāore e nui te whakatikatika i te ōwehenga mana o te ranunga hinu, ka kino pea te miihini.
Hei tāpiritanga, me tirotiro tonu te kukū o te mekameka kani. Ki te whakaritea ki te wā roa kua whakamahia ki roto i te mekameka kani, me whakakī pinepine ake te mekameka kani hou. I te nuinga o te wā i roto i te āhua makariri, ka taea tonu te kume i te taha o te pereti arataki o te kani mekameka i te taha o te arataki, engari ka taea tonu te kukume ā-ringa, hei whakamārama i te taumata kukū o te tika. Ina tae ki te pāmahana whakahaere, ka whānui te mekameka kani, ka tīmata te whakangā. Kāore e whakaaetia te hononga taraiwa ki te arahi i te taha o raro i waho o te mokowā arataki, ki te kore ka taka te mekameka kani. Ki te tika, me whakakī anō te mekameka kani. Ina tio, ka whakawhāiti te mekameka kani. Kua tae ki te wā ki te wetewete i te mekameka kani, ki te kore ka kino te toki porowhita me te peera.
● Ngā taipitopito mō te kore whakamahi i te kani mekameka
Kei te whakamahia te kani mekameka, he maha ngā mahi e hiahia ana kia aro nui ngā kaiwhakamahi ki ngā taipitopito. Tuatahi, tīmatahia te kani mekameka, ka tīmata a Mo i te pito o te taura. Ka tōia mārire te kakau tīmatanga ki te ringaringa, kia tae ki te tūranga mutu, kātahi ka tōia wawe ki raro i te wā kotahi, i mua i te pēhanga o te kakau. I kī te tohunga hangarau, kaua e tōia rawatia te taura tīmatanga kia tae ki te mutunga, kei whati pea. I te whakamahinga o ia rā, he maha ngā wā kāore ngā kaiwhakamahi e aro ki ngā taipitopito, ā, i te roanga o te wā, ka pakaru ngāwari te taura tīmatanga. Kia mahara hoki, kaua e tukua te kakau tīmatanga kia hoki whakamuri noa, me puhoi te whakahoki mai ki roto i te anga, kia pai ai te huri o te taura tīmatanga.
Tuarua, i muri i te whakamahinga, me waiho kia noho puku mō tētahi wā, kia rere ai te hau whakamatao, kia tukuna ai te wera nui o te mīhini. Ka taea te karo i te taumaha rawa o te wera i ngā wāhanga o te mīhini (te taputapu mura, te carburetor).
Anō, ki te heke te mana o te miihini, tera pea nā te tātari hau paru. Tangohia te taupoki o te pouaka carburetor, tangohia te tātari hau, tangohia te tātari huri noa i te paru, ka wehea ngā wāhanga e rua o te tātari, mā te nikau o te ringa ka horoia te tātari, mā te hau pēhi rānei mai i roto ki waho.
Ki te piri te paru o te tātari, me whakauru te tātari ki roto i te wai horoi motuhake, ki roto rānei i tētahi wai horoi kore-mura (pērā i te wai horoi ki te wai hopi mahana, horoia, whakamaroke). Kaua e whakamahia te paraihe hei horoi i te tātari huruhuru.
Tāutahia anō te tātari hau, kia mahara ki te tirotiro i te tatau, me te tirotiro hoki kei te tika te tūranga o te puna torsion.
● Ko te tiaki ā muri ake nei kia oti i te wā tika
Ko te tiaki i te kani mekameka, ko te mea nui ko te kani mekameka. Ko te tiaki tika me te whakakoi i te mekameka kani, he iti noa te pēhanga ka taea te uru ngāwari ki roto i te rakau i te wā e kani ana. I roto i te tiaki o ia rā, me aro ki te tirotiro i te pakaru me te whati o ngā hononga mekameka kani i runga i te rivet. Whakakapia ngā wāhanga kua pakaru, kua tawhito rānei o te mekameka kani, kātahi ka whakaranua ki ngā wāhanga hou o te āhua taketake me te rahi ōrite. He ātete te mekameka kani koranu mārō ki te pakū.
Ko te mekameka whakakoi kani, ko te tikanga mā ngā kaihoko ratonga e whakaoti. Me pupuri te whakakoi i te koki niho kani. Me rite te koki niho kani katoa, ki te rerekē, kāore e maeneene te hurihanga o te kani, ā, ka pakaru rawa, tae noa ki te whati o te mekameka kani. Me rite te roa o ngā niho kani katoa. Ki te kore, ka rerekē te teitei o te niho, ā, ka taea hoki te huri koretake o te mekameka kani, ka whati whakamutunga. I muri i te huri, me horoi pai te mekameka kani, me horoi ngā tuara, te puehu rānei o te kani, me te whakahinuhinu. Ki te kore e roa, me whakarite kia pai te whakahinuhinu o te mekameka kani.
Mō te rokiroki roa o te kani mekameka, me waiho ki tētahi wāhi e pai ana te hauhautanga, kia takoto kau te tāke wahie, kia ma hoki. Whakamarokehia te kāpata i mua i te whakahaere i te miihini, kia kore ai e piri te diaphragm kāpata. Horoia te mekameka kani me te arataki, tangohia, kātahi ka rehuhia ki te hinu ārai waikura. Horoia pai te mīhini, inā koa te tara whakamatao o te rango me te tātari hau. Mena ka whakamahia te hinu whakahinuhinu mekameka koiora, ka whakahinuhinuhia te tāke.
Kia mōhio mai, ahakoa e ai ki ngā whakaritenga o te whakamahinga me te tiaki i te kani mekameka, ka pakaru noa ētahi wāhanga o ngā mīhini hiko, nō reira me whakakapi wawe tonu kia rite ki te tauira me te whakamahinga. Kei roto i ēnei wāhanga: mekameka kani, pereti arataki, wāhanga tuku (pūmau, pūoro wira pūmau, wira mekameka), tātari, taputapu tīmata, mono mura me ngā wāhanga pūnaha whakamātao me ētahi atu.
