• For replacements use only the correct fuses or circuit breakers rated for use with the machine. Using
replacement devices not designed for use with the machine could lead to a fire and personal
injuries.
Organic Cleaners
• During preventive maintenance, never use any organic cleaners (alcohol, etc.) other than those
described in the service manual.
• Make sure the room is well ventilated before using any organic cleaner. 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 part that generates heat.
• Wash your hands thoroughly after cleaning parts with an organic cleaner to contamination of
food, drinks, etc. which could cause illness.
• Clean the floor completely after accidental spillage of silicone oil or other materials to prevent
slippery surfaces that could cause accidents leading to hand or leg injuries. Use “My Ace” Silicone
Oil Remover (or dry rags) to soak up spills. For more details, please refer to Technical Bulletin
“Silicone Oil Removal” (A024-50).
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. Excessive ozone could cause personnel working around the
machine to feel unwell.
Power Plug and Power Cord
• Before servicing 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.
