Mano a carbide ndi gawo la ntchito ya anyundo yamtchirechida. Idzavala nthawi zonse pamene ntchito ikupitirira. Pali njira ziwiri zothetsera vutoli: imodzi ndikunola mano, ndipo ina ndikusinthachitsamba nyundo wodzigudubuzas.

Monga katswirinyundo yamtchireogulitsa ma roller ku China, Sunny Superhard Tools amakulimbikitsani kuti musinthe zodzigudubuza m'malo monolera mano. Mukamagula zida za nyundo zakutchire, mutha kusunga zodzigudubuza za nyundo zachitsamba kuti zilowe m'malo. Zifukwa 2 motere:

• Ndizosavuta komanso zotsika mtengo kupanga m'malo kuposa kunola mano.
• Kuonjezera apo, nthawi zina, ngati mano ena a carbide athyoka, mano osweka sangathe kupangidwa.

Chogudubuza nyundo yakutchire patsamba ili chimabwera mu zidutswa 30 za mano a 4.7mm carbide. Kukonzekera kwapadera kwa mano a carbide kumabweretsa mapeto apadera. Mano apamwamba a YG8 carbide amatsimikizira magwiridwe ake apamwamba. Mapangidwe osasunthika a kapangidwe kake amatalikitsa moyo wake.

• Bush hammer roller ya mano 30 a carbide kuti alowe m'malo.
• Mano apamwamba a 4.7mm YG8 carbide amatsimikizira magwiridwe ake apamwamba.
