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.
