<Maintenance and Check Frequencies>
1. Preventative Maintenance Guidelines
The following maintenance frequencies are a guide to the replacement of parts as based on the results of periodic checks and scheduled frequency of repairs. They do
not imply that replacement is always necessary in accordance with the maintenance frequency (except for consumables such as fan belts).
Note that the following does not indicate maintenance periods.
Table 2 Maintenance and Check Frequencies
2. Cautions
• The maintenance and check frequencies in the table above are applicable under the following conditions of use.
A. Normal conditions of use, with infrequent starting and stopping (varies with model, however interval of starting and stopping would normally use is generally six times
or less per hour).
B. 24 hours using.
• The maintenance interval may need to be reduced under any of the following conditions.
1 Use under conditions of high temperature or humidity, or in locations in which variations in temperature and humidity are considerable.
2 Use in locations in which power supply variations (e.g. voltage, frequency, waveform distortion) are considerable. Note that the unit cannot be used outside the
allowable range of conditions.
3 Use in locations subject to considerable vibration and shock.
4 Use in an atmosphere containing toxic gases (e.g. dust, salt, sulfuric acid vapor, hydrogen sulfide) or oil mist etc.
• Unexpected events may occur even when periodic checks are implemented based on the check frequency. In such cases the appropriate repairs outside the period of
the warranty are chargeable.
