Safety Guidelines for the NASA Electric NS-539 Espresso Machine
For safe operation and long-lasting performance, always place the NASA Electric NS-539 Espresso Machine on a stable, flat surface and ensure the power supply matches the required 220–240V voltage. Keep the appliance away from water and use a properly grounded outlet.
During operation, the group head, steam wand, and other metal parts become very hot. Avoid direct contact to prevent burns, and never operate the machine with an empty water tank, as this may damage the internal components.
Before cleaning or maintenance, unplug the machine and allow it to cool completely. If the power cord or any electrical component is damaged, discontinue use and have it serviced by an authorized technician.
