I-XIXI ayinaso isikhathi sokubekezelela ukukhanya kwemvelo okuwuketshezi lwesisekelo, intombazane ethambisayo ekhanyayo ingenamanzi imisipha kanye ne-anti -sweat, akulula ukuyifaka ikhadi
Ukukhethwa kwamafutha okuxutshwe kwesikhumba samafutha ngenguqulo yezimonyo, isikhumba esomile esixutshwe nenguqulo eyomile yokukhetha i-hydraulic,uwoyela wesikhumba esomile nokukhethwa kwesikhumba okunesisipha, okungahlangani
Impushana izwakala ilula kakhulu, futhi i-smear ayibambekile.
Ukhilimu okhilimu ulula futhi uminyene, futhi ukuhlanganiswa nesikhumba kubekwe phezulu ngaphandle kokunamathela, futhi kukhona ukucwebezela kwemvelo ngaphakathi nangaphandle.
Ukubamba izimonyo: Ifanele isikhumba esinamafutha, esithambile futhi esikhanyayo, yenqaba ukuba buthuntu
Imodeli ye-Hydraulic: ilungele isikhumba esomile, esixutshwe noma izinkathi zasekwindla nasebusika, ifuna ukwenza ukwakheka kokukhanya okuthambile
Ngaphambi kokusetshenziswa: amaphutha asobala, ithoni yesikhumba engalingani
Ngemuva kokusetshenziswa: ithoni yesikhumba ihlanzekile ngokulinganayo, amaphutha afihliwe
Umphumela wokusetshenziswa uyahlukahluka kumuntu nomuntu
