Pomanga, kutentha sikuyenera kupitirira 35 ℃. Gawo lachiwiri la putty pakhoma sayenera kuphwanyidwa mowonda kwambiri.
Ngati pali chodabwitsa chowumitsa msanga, m'pofunika kuyang'ana ndikuzindikira ngati chinayambitsidwa ndi ndondomekoyi.
Ngati kuyanika kwachangu kumachitika, tikulimbikitsidwa kuti ntchito yomangayo iyenera kumalizidwa kwa maola pafupifupi 2 pambuyo pomanga kale pamene pamwamba pauma, motere kumathandiza kuchepetsa kuyanika mofulumira.
Sankhani ether yapamwamba ya cellulose yokhala ndi ntchito yabwino yosungira madzi komanso kugwira ntchito ngakhale nyengo yachilimwe.
