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.
⅜ 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.
