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.
