Kusintha kwa thumba la fumbi kumatengera momwe zinthu zilili, koma nthawi zambiri zimalimbikitsidwa kuti zigwiritsidwe ntchito kwa miyezi itatu mpaka chaka chimodzi.
Zotsatirazi ndi kufotokoza kwachindunji kwa kuzungulira kwa chikwama cha fumbi:
1. Kusintha kwa thumba la fumbi kumakhudzana ndi kugwiritsidwa ntchito. M'mabanja osiyanasiyana kapena zochitika zogwiritsira ntchito, chotsukira mpweya kapena chotsuka chotsuka chimakhala ndi katundu wosiyanasiyana pathumba lafumbi. Ngati nthawi zambiri imakhala yolemetsa-yambiri, chikwama cha fumbichi chimatha kukhuta mwachangu ndipo chimafunika kusinthidwa.
2. Ubale pakati pa mphamvu ya thumba la fumbi ndi kuzungulira m'malo. Mphamvu ya thumba la fumbi ndi yosiyana, ndipo kuzungulira kwake kudzakhalanso kosiyana. Chikwama chachikulu-chikhoza kusunga fumbi ndi zinyalala zambiri, kotero kuti kusintha kwake kumakhala kotalika.
3. Kufunika kosunga mpweya wabwino ndikusintha nthawi yake. Ntchito yaikulu ya thumba la fumbi ndikusonkhanitsa fumbi ndi zonyansa kuti mpweya ukhale woyera. Ngati thumba la fumbi silinasinthidwe kwa nthawi yayitali, lingayambitse mavuto a mpweya, monga kuwonongeka kwa mpweya kapena kuipitsa kwachiwiri. Choncho, kuyendera nthawi zonse ndikusintha matumba a fumbi ndi sitepe yofunikira kuti mpweya ukhale wabwino.
4. Malangizo onse ndi ntchito yeniyeni. Ngakhale matumba ambiri a fumbi amafunika kusinthidwa pambuyo pa miyezi 3 mpaka chaka chimodzi chogwiritsidwa ntchito, ogwiritsa ntchito ayenera kupanga ziganizo malinga ndi momwe zilili. Ngati thumba lafumbi ladzaza kapena kuwonongeka msanga, liyenera kusinthidwa munthawi yake. Panthawi imodzimodziyo, kuyeretsa nthawi zonse ndi kuyang'anitsitsa thumba la fumbi ndilofunikanso kuti mugwiritse ntchito bwino.
Mwachidule, kuzungulira kwa thumba la fumbi kuyenera kuganiziridwa mozama kutengera momwe amagwiritsidwira ntchito, mphamvu ya thumba la fumbi, komanso zofunikira za mpweya. Ogwiritsa ntchito amayenera kuyang'ana momwe chikwama cha fumbi chilili ndikuchisintha pakafunika nthawi kuti awonetsetse kuti chikwamacho chili ndi mpweya wabwino komanso kugwiritsa ntchito bwino.
