SAFETY PRECAUTIONS
The following precautions should be observed when servicing. 1. Since many parts in the unit have special safety-related characteristics, always use genuine Hitachi�s replacement parts. Especially critical parts in the power circuit block should not be replaced with other makers. Critical parts are marked with _ in the circuit diagram and printed wiring board. 2. Before returning a repaired unit to the customer, the service technician must thoroughly test the unit to ascertain that it is completely safe to operate without danger of electrical shock.
