SERVICE AND REPAIRS
All quality compressors will eventually require servicing or replacement of parts because of wear and tear from normal use. To assure that only genuine replacement parts will be used, all service and repairs must be performed by a HITACHI AUTHORIZED SERVICE CENTER, only.
NOTE:
Specifications are subject to change without any obligation on the part of the HITACHI.
NOTE:
Replace the filter element when it becomes dirty.
2.Draining tank:
Gradually open the drain valve, and drain out the air in the tank. (Fig. 6)
Close tightly when drained.
