Hazvina mhosva kuti rudzii rwemichina yemagetsi, kudzivirira mvura inyaya inofanirwa kutariswa.Izvi zvakafanana kune polyurethane foaming machines.Michina iyi inogadzirwa nekugadzira magetsi.Kana mvura ikapinda, haingokonzeri kushanda kwakajairika, asiwo kupfupisa hupenyu hwemuchina.

1. Pfeka midziyo yekudzivirira paunenge uchisanganisa maviri ekugadzirisa masheya;
2. Kufefetedza kwakanaka uye kuchena munzvimbo yekushanda;
3. Kana iyo ambient tembiricha yakakwira zvakanyanya, ichaita kuti mvura inyunguduke uye pachava nekumanikidza.Panguva ino, chifukidzo chekutsvaira chinofanira kuvhurwa pakutanga, uye ipapo chifukidzo chebhari chinofanira kuvhurwa mushure mokunge gasi rabudiswa;
4. Kana iyo polyurethane foaming muchina ine murazvo unodzoreredza zvinodiwa pafuro, murazvo wekuwedzera unodzoreredza unofanirwa kushandiswa;
5. Chiyero chacho chinofanira kunge chakanyatsogadziriswa mukugadzirisa kupupa kwemaoko;
6. Kana ganda redu richisangana zvakananga nemhinduro yepakutanga, tinofanira kuishambidza nesipo nemvura pakarepo.Kana ikasangana neB zvinhu, tinofanira kuipukuta pakarepo nekotoni yezvokurapa, togeza nemvura kwemaminetsi gumi nemashanu, uye tosuka nesipo kana doro.
