During Maintenance
- General -
• Before you begin a maintenance procedure always switch the machine off.
• Disconnect the power plug from the power source.
• Allow the machine to cool for at least 10 minutes.
• Avoid touching the components inside the machine that are labeled as hot surfaces.
- Safety Devices -
• Never remove any safety device (a fuse, thermistor, etc.) unless it requires replacement. Always
replace a safety device immediately.
• Never do any procedure that defeats the function of any safety device. Modification or removal of a
safety device (fuse, thermistor, etc.) could cause a fire and personal injury. After removal and re-
placement of any safety device, always test the operation of the machine to ensure that it is operating
normally and safely.
• For replacement parts use only the correct fuses, thermistors, circuit breakers, etc. rated for use with
the machine. Using replacement devices not designed for use with the machine could cause a fire
and personal injuries.
- Organic Cleaners -
• During preventive maintenance, never use any organic cleaners (alcohol, etc.) other than those de-
scribed in the service manual. (Refer the “2. Preventive Maintenance” in the Service Manual.)
• Make sure the room is well ventilated before using any organic cleaner. Always use organic solvents
in small amounts to avoid breathing the fumes and becoming nauseous.
• Switch the machine off, unplug it, and allow it to cool before doing preventive maintenance. To avoid
fire or explosion, never use an organic cleaner near any component that generates heat.
• Wash your hands thoroughly after cleaning parts with an organic cleaner to avoid contamination of
food, drinks, etc. which could cause illness.
