Tlhaloso e Khutšoanyane:
DPM150 ke terata e koahelang e etselitsoeng maemo a ho robeha ha matla. Sebopeho sa tšepe e tjheseletsang se teteaneng, bothata bo hodimo, mme se na le kganyetso e ntle ya ho robeha le kganyetso e ntle ya mapetso. E loketse ho lokisa cladding kapa ho matlafatsa mesebetsi e kang diphaephe tsa ho tjhesa oli, di-scraper tsa morafo wa mashala, le dihamore tsa ho qhaqha.
