/ 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 re-
placement parts. Especially critical parts in the power circuit block should not be replaced with other makers.
Critical parts are marked with AX 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.

SPECIFICATIONS AND PARTS ARE SUBJECT TO CHANGE FOR IMPROVEMENT.
