Anthu ogwira ntchito kumapiri ndi mafakitale omwe amapanga masisitere pamakoma. Kukonzekera kumaperekedwa kudzera mu zipinda, ziphuphu ndi zinthu zina. Zosiyanasiyana ndi mawonekedwe a zinthu zimakulolani kuzigwiritsira ntchito ngakhale njira zowonongeka zogwirira ntchito.
Mitundu ya ogwira pansi pa masamulovu
Malinga ndi njira yokwera phirilo, pali mitundu iwiri ya ogwira ntchito:
- amaikidwa mkati mwa alumali (amadziwika ndi miyeso yaing'ono, saoneka kuchokera kunja, amagwiritsidwa ntchito pokonza masamulo amkati mwa mipando);
- inayikidwa ndi kutsegula kotseguka (pofuna kuteteza masalefu otseguka, ogwiritsa ntchito kupanga mapangidwe).

Galasi lamakabatila pamakoma
Masamba a galasi ali ndi mawonekedwe okongola kwambiri. Posachedwapa, nthawi zambiri amagwiritsidwa ntchito popangira chipinda chokongoletsera. Ndizodziwikiratu kugwiritsa ntchito galasi lamagalasi m'mabulumba mu bafa.
Pali njira ziwiri zomwe mungasankhire olemba magalasi:
- Zithunzi zazikulu zomwe zidzaperekedwe pachiyambi. Mwachitsanzo, ogwira ntchito ya "pelican" kapena "tukan", opangidwa ngati mlomo wa mbalame;
- zochepa ndi zosawoneka, zomwe zingapangitse chinyengo kuti alumali amaimitsidwa pakhoma popanda kugwiritsa ntchito zida zowonjezera.

Monga lamulo, ogwila amapangidwa ndi zipangizo zotere: silumin (zinc-aluminium aloyi) kapena chitsulo. Amapereka mphamvu ndi kudalirika kwamtundu wake. Ma gaskets omwe amagwira ntchito pamapangidwe amapangidwa ndi pulasitiki kapena silicone. Amapewa kuwonongeka kwa masamulo kuchokera mu galasi .
Kusankha mosamalitsa mwiniyo pa alumali pa khoma, mudzapereka kuyang'ana kwathunthu ndi kolumikizana ndi kapangidwe ka chipinda chanu.
