SERVICE AND REPAIRS
All quality tools will eventually require servicing or replacement of parts due to wear from
normal use. These operations should ONLY be performed by an authorized service center.
DOUBLE INSULATION SYSTEM ENHANCES SAFE OPERATION
To enhance safe operation of this electric power tool, HITACHI has adopted a double
insulation system. The term “double insulation” used here denotes an insulation system
with two insulations physically separated and arranged between the electrically conductive
material connected to the power supply and the outer frame subject to contact by the
operator.
Thus, the power tool is termed double insulated and both the “ ”
mark and “Double insulation”, or either one is indicated on the name
plate.
While no external grounding is required with this system, normal safety
precautions as outlined in this manual must still be followed.
