Imininingwane Yomkhiqizo

Ukusetshenziswa: Kusetshenziswa njenge-ejenti yokuhlanza, ukungathathi hlangothi, ukulondolozwa kanye nombala kokulungisa ukuvikela ama-colos wemvelo wezilwane nezitshalo.

Ukupakisha: Igcwele isikhwama se-polyethylene njengesendlalelo sangaphakathi, nesikhwama sokwelulwa sepulasitiki esihlanganisiwe njengesendlalelo sangaphandle. Isisindo esinetha lesikhwama ngasinye singama-25kg.

Isitoreji Nezokuthutha: Kufanele igcinwe endaweni yokugcina yokugcina eyomile futhi yomoya osomile, igcinwe kude nokushisa nasemswakama ngesikhathi sokuhamba, ilayishwe ngokunakekelwa ukuze igweme ukulimala. Ngaphezu kwalokho, kufanele igcinwe ngokwahlukana ezintweni ezinobuthi.
