(3) Theumninimile emthandweniKufanele ilayishwe kwi-alloy steel umthelela emthonjeni omncane noma okujwayelekile kokumba ngaphakathi kohlu oluvumelekile lwe-Φ6-5mm ngokwezidingo ezibonakalayo. Ukusetshenziswa kokushayela okungaphandle kwebanga akuvunyelwe ngokuphelele.
(4) Ucingo olushayelwa umthelela kufanele luvikelwe kahle. Kuyenqatshelwe ngokuphelele ukudonsela emhlabathini ukuvikela ukuchotshozwa nokusikwa, futhi akuvunyelwe ukudonsela ucingo emanzini anamafutha ukuvikela uwoyela namanzi kusuka ku-corloding ngocingo.
. Uma kutholakala ukuthi umthelela wokuvuza unokuvuza, ukudlidliza okungajwayelekile, ukushisa noma umsindo ongajwayelekile ngesikhathi sokusetshenziswa, kufanele ayeke ukusebenza ngokushesha futhi athole ugesi wokuhlola nokulungisa ngesikhathi.

(7) Lapho usebenzisa umthelela wokushayela umthelela, khumbula ukungasebenzisi amandla amaningi noma ukuwusebenzisa ku-skewed. Qiniseka ukuthi uqinisa kahle umdlandla ngaphambi kwesikhathi futhi ulungise ukujula kwegeji ye-hammer drill. Isenzo esime mpo naselinganiselayo kufanele senziwe kancane futhi ngokulinganayo. Ungakuguqula kanjani i-drill bit lapho inomthelela e-drill kagesi ngamandla, ungasebenzisi amandla amaningi ekudleni okuncane.
