• Hazard warnings in this manual or on the storage system cannot cover
every possible case, because it is impossible to predict and evaluate all
circumstances beforehand. Be alert and use common sense.
• To verify normal operation, operate the storage system according to the
information in this manual.
Read the following safety guidelines carefully and follow them when you
conduct maintenance of the machine:
• Do not use materials that are outside the specifications for the storage
system.
• Use the spare parts, consumables, and materials for maintenance that are
specified in this manual; otherwise, personal injury, system damage, and
degradation in system quality can occur.
• Keep the maintenance area neat.
• Always put away parts, materials, and tools when not in use.
Handling of heavy parts
• When lifting a heavy object, hold it close to yourself and keep your back
erect to prevent back injury.
• When lifting an object designated with a caution in this manual, use a
proper lifting tool or ask someone to assist you.
Preventing electric shock
• Before starting work, be sure that, unless otherwise specifically instructed,
there is no potential electric hazard in the maintenance area such as
insufficient grounding or a wet floor.
• Before starting work, know where the emergency off switches are located
and know how to operate them.
• Unless otherwise specifically instructed, remove all power sources to the
machine before starting maintenance. Switching off the storage system
power supplies is usually not sufficient.
• Do not touch any uninsulated conductor or surface that remains charged
shortly after the external power supply to the storage system is
disconnected.
• Do not replace parts during a thunderstorm.
Avoiding rotating or moving parts
• Do not supply power to any device with rotating or moving parts that are
not properly covered.
• Tuck in your tie, scarf, shirt, or any other loose clothing to prevent it from
getting caught by a rotating or moving part.
