Ngati tsamba law silinaikidwe molondola, ngozi zitha kuchitika pakugwiritsa ntchito (monga
chiwawa), kapena musamalire werengani zida ndi macheka mawotchi musanagwiritse ntchito.
Njira zodzitetezera ndi monga :
Mukayika tsamba la macheka, samalani komwe pamazungulira. Macheke aakulu ndi ang’onoang'ono amazungulira mosiyana (kutengera komwe mano akulowera).
Mukayika tsamba la macheka, samalani pa kuyeretsa shaft macheka, pukutani fumbi ndi macheka.
fumbi pa shaft yocheka, kupewa kupendekera pantchito.
Mtedza ndi kukonza mtedza ziyenera kulimba isanagwire ntchito. Ngati zinthu ziloleza,
kuzungulira kwa macheka kuzungulira kungathe kuyezedwa pogwiritsa dial gauge pambuyo pake.
kukhazikitsa.
Zovuta zofala ndi mayankho:
①kuphulika pa m'mphepete pa bolodi:tsamba ndi macheka ndipo kapena
ndipo ikufunika kusinthidwa ndi chatsopano .
②kuphulika mbali imodzi ya m'mphepete pansi pa bolodi:macheka wachikulu ndi macheka wothandizira
sizili mumzere wowongoka, sinthani njira yowona kumanzere ndi kumanja.
③kuphulika m'mbali zonse zonse za m'mphepete pansi pa bolodi: mbali zonse ndi
kuphulika, ndi yolembela si sakwanira Sinthani.
shaft mmwamba ndi pansi yodulira.
④Maonekedwe a pamwamba: Tsamba la macheka ndi lopanda kapena lili mabokosi m mano omwe ayenera kukhala
kusinthidwa kapena kutumizidwa kuti akupera.
⑤Masamba oola kapena mano osowa: akhoza kutumizidwa kuti akupera ndi kukonza,
ndi mutakweza, ndasunga ndalama.
