Toosin

Burburinta ka dib, alaabta waxaa la dhex maraa toddobo rullaluistuyaal toosin ah si loo gaaro toosinta saxda ah ee tuubooyinka.

Eddy hadda

Toosin ka dib, tuubo kasta waxaa la dhex maraa mishiinka hadda jira ee eddy si loo ogaado dildilaaca dusha sare iyo cilladaha kale.Kaliya tuubooyinka gudbiya qulqulka qulqulka ayaa ku habboon in la geeyo macaamiisha.

Dhamaystirka

Tuubo kasta waxaa lagu saliiday saliid u adkaysata daxalka ama lagu dahaadhay ilaalinta dusha sare iyo daxalka u adkaysta sida looga baahan yahay macaamiisha, dhamaadka tuubada kasta waxaa lagu daboolaa daboolo caag ah si looga fogaado waxyeelo soo gaarto gaadiidka, calaamadaynta iyo faahfaahinta waa la dhejiyaa alaabtuna waa diyaar in la diro .
