SAFETY PRECAUTION
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 A\ in the schematic diagram and circuit board diagram.
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.
