injuries.
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.
Lithium Batteries
5

• Always replace a lithium battery on a PCB with the same type of battery prescribed for use on that
board. Replacing a lithium battery with any type other than the one prescribed for use on the board
could lead to an explosion or damage to the PCB.
• Never discard used batteries by mixing them with other trash. Remove them from the work site and
dispose of them in accordance with local laws and regulations regarding the disposal of such items.
Ozone Filters
• Always replace ozone filters as soon as their service life expires (as described in the service manual).
An excessive amount of ozone can build up around machines that use ozone filters if they are not
replaced at the prescribed time.
• The room where the machine is located must be well ventilated. Excessive ozone could cause per-
sonnel working around the machine to feel unwell.
Power Plug and Power Cord
• Before serving the machine (especially when responding to a service call), always make sure that the
power plug has been inserted completely into the power source. A partially inserted plug could lead
to heat generation (due to a power surge caused by high resistance) and cause a fire or other
problems.
• Always check the power plug and make sure that it is free of dust and lint. Clean it if necessary. A
dirty plug can generate heat which could cause a fire.
• Inspect the length of the power cord for cuts or other damage. Replace the power cord if necessary.
A frayed or otherwise damaged power cord can cause a short circuit which could lead to a fire or
personal injury from electrical shock.
• Check the length of the power cord between the machine and power supply. Make sure the power
cord is not coiled or wrapped around any object such as a table leg. Coiling the power cord can
cause excessive heat to build up and could cause a fire.
• The machine must be located near its power source. The area around must be free of obstacles so
the power cord can be disconnected quickly in case of an emergency.
• Make sure that the power cord is grounded (earthed) at the power source with the ground wire on
the plug.
• Connect the power cord directly into the power source. Never use an extension cord.
• When you disconnect the power plug from the power source, always pull on the plug, not the cable.
