Kumanga

Mitundu yonseyi ili ndi zotchingira zokhuthala, mawaya awiri ndi zotchingira. Insulation, monga imadziwika, imagwiritsidwa ntchito kuteteza woyendetsa kuzinthu zakunja. Zingwe zimakulungidwa ndikukulungidwa, kusungidwa m'matumba olimba, nthawi zambiri amapondedwa ndi kupindika. Maziko ndi kukana kwabwino pazifukwa zomwe tatchulazi komanso kusinthasintha. Kuteteza kumachitidwa pofuna kuteteza chizindikiro kuti chisasokonezedwe ndi chilengedwe. Nthawi zambiri mu mawonekedwe a aluminiyamu zojambulazo, mkuwa kapena aluminiyamu kuluka.

Kusiyana kwakukulu

Kukambitsirana

Choyambitsa chachikulu cha mavuto ndi kuwonongeka kwa machitidwe omwe takambirana pamwambapa ndi zingwe zotsika kwambiri komanso zolumikizira zowonongeka, chifukwa chake ndikofunikira kugwiritsa ntchito zingwe zokhazokhazokha komanso zokhala ndi zolumikizira zabwino.

Ngati tili ndi makina owunikira ambiri okhala ndi zida zambiri, mawaya angapo kapena mazana angapo, ndikofunikira kuwonjezera pazingwe zodzipatulira za DMX. Izi zipangitsa kuti dongosololi lizigwira ntchito moyenera komanso kutipulumutsa ku nthawi zosafunikira, zamanjenje.
