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 eff ective, 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.
