Treatment

 

 

For ventilation, holes are provided in the cabinet to prevent a temperature rise. Do not block the

 

 

ventilation holes. Good ventilation is necessary.

 

 

Never allow a liquid such as water and chemical solution and a metallic object like a copper wire

 

 

inside the JW-21MN to avoid a possible hazard. Otherwise, it may be a cause of machine trouble.

 

 

When a trouble or abnormal condition such as overheat, fume, or smoke is met, stop the operation

 

 

immediately, and call your dealer or our service department.
