Recommended inspection and maintenance cycles
[Note: The maintenance cycle is not the same as the warranty period.]
Table 1 assumes the following usage conditions.
1. Normal use without frequent starting and stopping of the machine.
(Although it varies with the model, we recommend not starting and stopping the machine more than 6 times/hour for
normal use.)
2. Operation of the product is assumed to be 10 hours/day, 2500 hours/year.

Note 1
This table indicates main parts.
See the maintenance and inspection contract for details.
Note 2
This maintenance cycle indicates recommended lengths of time until the need arises for maintenance work, in order to ensure
the product is operational as long as possible.
Use for appropriate maintenance design (budgeting maintenance and inspection fees, etc.).
Depending on the content of the maintenance and inspection contract, the inspection and maintenance cycles may in reality
be shorter than those listed here.
Shortening of “maintenance cycle” and “replacement cycle” needs to be considered in the following cases.
1.
When used in hot, humid locations or locations where temperature and humidity fluctuate greatly.
2.
When used in locations where power fluctuation (voltage, frequency, wave distortion, etc.) is high.
(Cannot be used if it is outside the allowable range.)
3. When installed and used in locations where bumps and vibrations are frequent.
4.
When used in bad locations where dust, salt, harmful gas or oil mist such as sulfurous acid and hydrogen sulfide may be
present in the air.
5. When used in locations where the machine is started and stopped frequently or operation time is long. (Example: 24 hour
air-conditioning)
