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
insulation-feature.
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
In addition to the precautions mentioned above, following particular precautions for this
demolition hammer should be followed.
1. Use earplugs to keep your ears noise-free while working.
2. Wear protective shoes to protect your feet.
3. Properly set the bit holder.
4. Always hold the body handle and side handle of the power tool firmly. Otherwise the
counterforce produced may result in inaccurate and even dangerous operation.
5. Since the bit becomes very hot during operation, do not touch it because you are burnt.
6. At the start of work, confirm screw tightening.
7. When working at a highly elevated location, pay attention to articles and persons below.
