Maintenance

 

Proper maintenance can prevent many early faults and regular careful cleaning can 
make the machine work like it’s brand new.

 

Please unplug the power cable before cleaning and maintenance to prevent electric shock.

 

Clean Screen

 

Please mix and stir a little fabric softener or tableware detergent with alcohol. 

Please use a soft cloth to be completely soaked in the mixture.

 

Please take out the cloth and twist to a half-dry state to wipe the machine screen.

 

Repeat several times, paying attention to not squeeze the water flow into the 
machine when wiping.

 

Clean Face Frame

 

Please use a dry, soft, lint-free cloth to wipe the front frame.

 

No Use of Machine for a Long Period

 

If the machine has not been used for a long period—such as a holiday—please make sure 
to unplug the power cable to prevent any possible dangers caused by power supply ripple 
from lightning.
