1. Ngaphambi komsebenzi, u-opharetha kufanele aqale aqonde imithetho efanele kumanuwali ukuze asetshenziswe isiseshiumshini wokudubula, futhi baqonde ngokugcwele ukwakheka nomsebenzi wemishini.

2. Ngaphambi kokuqala umshini, opharetha kufanele ahlole ukuthi izinsimbi zikhululekile yini nokuthi isimo esibushelelezi somshini siyahlangabezana yini nezidingo.

3. Umshini wokuqhumisa isibhamu sohlobo lwe-crawler udinga ukufakwa okunembile. Ngaphambi kokuqala umshini, ukuhlolwa kwesenzo esisodwa kufanele kwenziwe engxenyeni ngayinye kanye nemoto. Ukuzungezisa kwenjini ngayinye kufanele kunembile, amabhande okukhasa kanye namabhande kufanele aqine ngokulingene, futhi akumele kube khona ukuchezuka.

4. Hlola ukuthi ingabe amandla akhona angalayishi enjini ngayinye, ukukhuphuka kwezinga lokushisa elithwele, isinciphisi, nomshini wokuqhumisa isibhamu kusebenza kahle. Uma izinkinga zitholakala, izici kufanele ziphenywe futhi zilungiswe ngesikhathi.

5. Ngemuva kokuthi kungabikho nkinga ekuhlolweni komshini owodwa, ukuhlolwa kokungenzi lutho komqoqi wothuli, ukuphakamisa, ukuzungezisa isigubhu nokuqhunyiswa kwesibhamu kungenziwa ngokulandelana. Isikhathi sokungenzi lutho siyihora elilodwa.

Isakhiwo somshini wokuqhumisa isibhamu sokudubula:

Umshini wokuqhumisa i-Crawler shot uyithuluzi lokuhlanza elincane, ikakhulukazi elakhiwe igumbi lokuhlanza, umshini wokudubula oqhumayo, ikheshi, isihlukanisi, isixhumi esihambisa isikulufu, ipayipi lokususa uthuli nezinye izingxenye. Igumbi lokuhlanza Igumbi lokuhlanza lenziwe ngepuleti lensimbi kanye nesakhiwo esishiselwe insimbi. Yindawo yokusebenza evaliwe futhi evulekile yokuhlanza izinto zokusebenza. Iminyango emibili ivuleka ngaphandle, engandisa indawo yokuhlanza yomnyango.
