Ukudubula ezindaweni ezihlosiwe phansi ezihluka ngokwesikhundla, isiqondiso, ibanga, kanye nesivinini
Ukudubula ezinhlosweni ezihambayo phansi, ukudubula ezinhlosweni phansi ezishintsha njalo endaweni, isiqondiso, ibanga kanye nesivinini. Njengoba indawo okuqondiswe kuyo ingaguquki, futhi isiqondiso sokugijima, ibanga kanye nesivinini kuvame ukushintsha, ukuze isibhamu sishaye ilitshe, kufanele kuthathwe umholi. Uma udubula ilitshe uhamba ngendlela evundlile, kufanele uhole phambi kokunyakaza kwelitshe bese uhambisa umugqa wokuhlosa phambili kwelitshe. Uma udubula ilitshe elihambayo eliyindilinga, phinda ukuqhubela phambili okuvundlile ngomsebenzi we-oblique angle. Uma udubula ilitshe elihambayo ngendlela evundlile, isibhamu somshini wezinyawo sivame ukufakwa igeyiji yebanga ngenxa yendlela yaso ephansi, futhi ukudubula kwenziwa ngokuphakamisa noma ukwehlisa indawo okuqondiswe kuyo. Izikhali zidubula emathangini nasezimotweni ezihamba ngendlela evundlile. Ngenxa yokuthi ilitshe lihamba ngokushesha, ngokuvamile lidubula ngokushintsha i-reticle.
