Tlhaloso ea Sehlahisoa
Likarolo tsa mantlha tsa letoto la 4R letoto la 52 le sebetsang ka letsoho le kenyelletsa:
1.Taolo e sebetsang hantle: Moralo oa lever oa valve o sebetsang ka letsoho o etsa hore taolo ea moea e nepahale le ho tenyetseha, e lumellang hore ho be le phetoho e nepahetseng ea boholo ba moea le tataiso.
2.Ho tšepahala: Valve ea tataiso e nka likarolo tsa boleng bo phahameng ba ho tiisa ho tiisa ho tiisa le ho tsitsa ha moea. Ho sa le joalo, sebopeho sa eona se bonolo ebile se bonolo ho se hlokomela le ho se lokisa.
3.Ho tšoarella: 'Mele o ka sehloohong oa valve o sebelisoang ka letsoho o entsoe ka thepa e tšoarellang, e ka mamellang khatello e phahameng le litlhoko tsa tšebeliso ea nako e telele. E na le khanyetso e ntle ea ho apara le ho hanyetsa kutu.
4.Polokeho: Moralo oa valve o sebetsang ka letsoho o lumellana le litekanyetso tse nepahetseng tsa polokeho, ho netefatsa polokeho le ts'epo nakong ea ts'ebeliso.
