5 Likhomaretsi tsa Lithaele
①Ho bonolo ho omisa metsoako ea metsoako, ha ho na makukuno a tla hlahisoa, lebelo la kopo le tla eketseha, ts'ebetso ea kaho e tla ntlafatsoa, nako ea ho sebetsa e tla bolokeha, 'me litšenyehelo tsa ho sebetsa li tla fokotseha.
②Ka ho eketsa nako ea ho bula, e ntlafatsa ts'ebetso ea lithaele mme e fana ka phello e ntle ea ho khomarela.
6 Thepa ea ho ikemela fatše
① E fana ka viscosity mme e ka sebelisoa e le thuso e khahlanong le ho rarolla.
② Ntlafatsa ho pompa ha metsi le ho ntlafatsa ts'ebetso ea ho betla.
③ Laola ho bolokoa ha metsi le ho honyela ho fokotsa mapetsong le ho honyela ha mobu.
7 Pente e entsoeng ka metsi
①Thibela pula e matla le ho lelefatsa nako ea sejana sa sehlahisoa. Botsitso bo phahameng ba likokoana-hloko le ho lumellana ho babatsehang le likarolo tse ling.
② Ntlafatsa mokelikeli, fana ka khanyetso e ntle ea ho phatloha, ho hanyetsa le ho leka-lekanya, 'me u netefatse hore ho na le qetello e ntle ea holim'a metsi.
8 wallpaper phofo
① Qhibiliha kapele ntle le agglomeration, e loketseng ho tsoakoa.
②Fana ka matla a phahameng a tlamo.
9 Boto ea samente e atolositsoeng
① E na le sekhomaretsi se phahameng le mafura, 'me e ntlafatsa ts'ebetso ea lihlahisoa tse fetisitsoeng.
② Ntlafatsa matla a botala, ho khothaletsa hydration le phello ea ho folisa, le ho ntlafatsa chai.
