Safety Devices
• Never remove any safety device unless it requires replacement. Always replace safety devices
immediately.
• Never do any procedure that defeats the function of any safety device. Modification or removal of
a safety device (fuse, switch, etc.) could lead to a fire and personal injury. Always test the
operation of the machine to ensure that it is operating normally and safely after removal and
replacement of any safety device.
• 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).
Lithium Batteries
• 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.
