gaasta dhoobada ah ee dhoobada ah waa jilicsan, miisaan culus oo dabacsan, oo leh sifooyin heerkulkiisu sareeyo. Waa doorasho aad u fiican oo ah shaambeyn kulul oo jaban oo leh cadaadin hooseeya oo loo baahan yahay. Maadaama ay jilicsan yihiin oo si sahal ah looma dhejin karo si aad u samaysato shaar kale, flange dhamaystiran ma aha mid muhiim ah marka la isticmaalayo qalabkaan.
Duufaan dhoobo ah
Gubashooyinka dabiiciga ah ee khatarta ah waa kuwo jilicsan, fudud oo dabacsan, oo leh sifooyin heerkulkiisu sareeyo. Waa doorasho aad u fiican oo ah shaambeyn kulul oo jaban oo leh cadaadin hooseeya oo loo baahan yahay.Sincethey waa jilicsan oo si sahlan ayaa loogu duubi karaa si ay u sameeyaan daloolo dhaadheer, dhammaadka flangelku maaha mid aad muhiim u ah marka la isticmaalayo qalabkaan.
