Note 1)  Random fault is an unexpected failure which occurs before 

the wear is progressed, within the service life of the parts and 
equipment. It is difficult to establish a technological measure 
against the random fault. At the moment, statistical handling is the 
only measure against the random fault.

Note 2)  The elapsed year marked with * assumes the operating time 

as 10 hours/day and 2500 hours/year in a normal operating 
condition without frequent start/stop. This may vary according to 
the operating condition. Please check the calculation basis of the 
elapsed year when making a maintenance contract.

Note 3) 

 illustrates the estimated timing when the wear-out 

failure starts and how the failure rate increases as the time passes.
