CAUTION
• A toothed washer and spring washer, if used originally, must be reinstalled.
Omitting them may result in contact failure which could cause an electric shock
or fire.
• When reassembling parts, make sure that the correct screws (size, type) are
used in the correct places. Using the wrong screw could lead to stripped
threads, poorly secured parts, poor insulating or grounding, and result in a mal-
function, electric shock or injury.
• Take great care to avoid personal injury from possible burrs and sharp edges on
the parts, frames and chassis of the product.
• When moving the product or removing an option, use care not to injure your
back or allow your hands to be caught in mechanisms.
• Wherever feasible, keep all parts and covers mounted when energizing the
product.
• If energizing the product with a cover removed is absolutely unavoidable, do not
touch any exposed live parts and use care not to allow your clothing to be
caught in the moving parts. Never leave a product in this condition unattended.
• Never place disassembled parts or a container of liquid on the product. Parts
falling into, or the liquid spilling inside, the mechanism could result in an electric
shock or fire.
• Never use a flammable spray near the product. This could result in a fire.
• Make sure the power cord is unplugged before removing or installing circuit
boards or plugging in or unplugging connectors.
• Always use the interlock switch actuating jig to actuate an interlock switch when
a cover is opened or removed. The use of folded paper or some other object
may damage the interlock switch mechanism, possibly resulting in an electric
shock, injury or blindness.
• The product must be placed on a flat, level surface that is stable and secure.
• Never place this product or its parts on an unsteady or tilting workbench when
servicing.
• Provide good ventilation at regular intervals if a service job must be done in a
confined space for a long period of time.
• Avoid dusty locations and places exposed to oil or steam.
• Avoid working positions that may block the ventilation ports of the product.
• Replace a rundown battery with the same type as specified in the manufac-
turer’s parts manual.
• Before installing a new battery, make sure of the correct polarity of the installa-
tion or the battery could burst.
• Dispose of used batteries according to the local regulations. Never dispose of
them at the user’s premises or attempt to try to discharge one.
