Using the Eurodib VM18 Vacuum Packaging Machine is a breeze. First, make sure it's plugged into a 120 - volt power source. If you're using bags, place your items inside and position the open end of the bag on the sealing beam. For containers, attach the external vacuum accessory. Then, select the appropriate settings on the digital control panel. Once everything is set, start the vacuuming and sealing process. As for maintenance, regularly clean the all - stainless - steel seamless chamber with a mild cleaner to keep it hygienic. The dehumidification self - maintenance program will help maintain the machine's performance, but if you notice any issues, it's best to contact customer support. Remember, use only the recommended bag types (SB, SCB, CB, and CCB) for optimal results.
