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.
