Mhlawumbe ungumshini wokuvumelanisa we-vacuum weMenenja yokuthenga okuhlinzayo, ofuna umshini wokuvumela osezingeni eliphezulu we-vacuum wokuhlinzwa , futhi i-mecanmed ingumenzi ochwepheshe nomhlinzeki ongahlangabezana nezidingo zakho. Hhayi nje umshini wokuvumelanisa we-vacuum wokuhlinzwa esikhiqize usebenze ngezitifiketi zezimboni zomhlaba wonke, kepha futhi singahlangabezana nezidingo zakho zokwenza ngokwezifiso. Sinikezela nge-inthanethi, inkonzo yesikhathi esifike ngesikhathi futhi ungathola ukuholwa ngochwepheshe kumshini wokuvumela we-vacuum wokuhlinzwa . Unganqikazi ukuxhumana nathi uma unentshisekelo ngomshini wokuvumelanisa we-vacuum wokuhlinzwa , ngeke sikuyeke phansi.
