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.
