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 "
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:
