DOUBLE INSULATION SYSTEM ENHANCES SAFE OPERATION
To enhance safe operation of this 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.
To maintain the effectiveness of the double insulation system, follow the precautions described below:
1.Always contact your dealer or an authorized service center when assembling, disassembling or replacing parts other than accessories or carbon brushes. Improper assembly and/or replacement with wrong parts may result in eliminating the double
2.Clean the exterior of the power tool with a soft cloth moistened with soapy water, and dry thoroughly. Chloric solvent, gasoline, and thinner will cause plastic components to
dissolve.
PARTICULAR PRECAUTIONS ON DEMOLITION HAMMER
