U lekola khatello ea mollo joang?
Ho hlahloba khatello ea mollo oa mollo, o ka latela mehato ena:
1. Bokella lisebelisoa tse hlokahalang:
Khatello ea Handue: Netefatsa hore o na le khatello ea khatello e ka lekanyang khatello ea khatello ea maikutlo.
Wrenches: Bakeng sa ho hokahanya morati ho pompo kapa piping.
Lisebelisoa tsa polokeho: Roala lisebelisoa tse loketseng tsa polokeho, ho kenyelletsa le liatlana le li-guggles.
2. Fumana koung ea liteko tsa khatello:

3. Hokela mohatla oa khatello:
Sebelisa litlolo tse loketseng ho hokahanya khatello ea maikutlo koung ea liteko. Netefatsa tiiso e tiileng ho thibela ho tsoa.
4. Qala pump ea mollo:
Bulela pompo ea mollo ho latela litaelo tsa moetsi. Etsa bonnete ba hore sistimi e boetse e loketse ho sebetsa.
5. Shebella ho bala ha khatello:
Hang ha pompo e ntse e matha, hlokomela ho bala ha khatello ka mor'a tekano. Sena se tla u fa khatello ea ho senya pompo.
6. Ngola khatello:
