CAUTION

1. Precautions for Service Jobs

•

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 mal­function, 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.

2. Precautions for Servicing with Covers and Parts Removed

•

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.
