Definitions for symbols used on this tool V volts Hz .......... hertz A amperes no .......... no load speed W watt Class II Construction ---/min ... revolutions per minute .......... Alternating current DOUBLE INSULATION FOR SAFER OPERATION To ensure safer operation of this power tool, HITACHI has adopted a double insulation design. "Double insulation" means that two physically separated insulation systems have been used to insulate the electrically conductive materials connected to the power supply from the outer frame handled by the operator. Therefore, either the symbol " " or the words "Double insulation" appear on the power tool or on the nameplate. Although this system has no external grounding, you must still follow the normal electrical safety precautions given in this Instruction Manual, including not using the power tool in wet environments. To keep the double insulation system effective, follow these precautions: ⅜ Only Hitachi Authorized Service Center should disassemble or assemble this power tool, and only genuine HITACHI replacement parts should be installed.
