■ Standard replacement cycle of the other principal parts
The estimated parts replacement cycles are shown in the following figure. They are based on the
assumption that they will be used under normal use conditions (average ambient temperature of
40°C, load factor of 80% or less, 24-hour operation per day, with no corrosive gas, oil mist, dust,
metal powder, etc. present). These replacement cycles are not the lives of the parts. They are based
on the assumption that more parts will become abnormal when they are used over these cycles.
