Ko te Haina VD4 raupapa mokorua ara iahiko-waahi he taputapu mo te whakauru i nga taputapu whakawhiti o roto.Tena koa whakapā atu ki a ROCKWILL mo nga whakaritenga whakaurunga motuhake.VD4-R raupapa ngaohiko reo wehe iahiko korehau me te tikanga whakahaere taha mo te whakaurunga o roto e whakaatu ana i te tikanga hanga pou motuhake.Kei ia pou he kaikokoti korehau ka mau ki roto i te kapia i te wa i hanga ai te rango na te mahi hanga motuhake.Ko tenei tikanga hanga e tiaki ana i te haukoti korehau mai i te ohorere, te parahanga me te tohanga.
Ko te tikanga whakahaere ko te momo hiko penapena kore-haere me te whakatuwhera me te kati motuhake ahakoa te mahi a te kaiwhakahaere.Ko te tikanga whakahaere e whakamahia whanuitia ana i roto i nga raupapa ara iahiko VD4-R katoa me te mana o mua.
Ka taea te whakahaere mamao te ara iahiko ina whakaurua ki nga taputapu hiko i whakatapua (te motika, te whakatuwhera me te kati te tuku).
Ko te tikanga whakahaere, ko nga pou e toru me nga pukoro o naianei (mehemea ka whakaratohia) ka whakauruhia ki runga i te anga whakarewa kahore he wira.Ko te hanga he tino totika, he pakari, he iti te taumaha.
VD4-R raupapa ara iahiko-waahi me nga tikanga whakahaere taha taha he taputapu hiri hiri mo te ora.(Paerewa IEC 62271-100)
