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:
- Only HITACHI AUTHORIZED SERVICE CENTER should disassemble or assemble this power tool, and only genuine HITACHI replacement parts should be installed.
- Clean the exterior of the power tool only with a soft cloth moistened with soapy water, and dry thoroughly.
Never use solvents, gasoline or thinners on plastic components; otherwise the plastic may dissolve.
