FOREWORD
The information in this manual applies to operation and maintenance of the Power Tool. Some
illustrations in this manual show details or attachments that might differ from your POWER TOOL.
And guards and covers may have been removed for illustrative purposes.
DOUBLE INSULATION FOR SAFER OPERATION
To ensure safer operation of this electric power tool, HITACHI has adopted a double insulation
system. "Double insulation” as used here, means a system of two insulations physically separated
and arranged between electrically conductive materials connected to the power supply and to the
outer frame handled by the operator. Therefore, the nameplate shows both the ” fa] " mark and
"Double insulation”, or either one on the power tool.
Although this system has no external grounding, you must still follow the normal safety
precautions given in this manual.
To keep the double insulation system effective, follow these precautions:
* To avoid lessening the double insulation-feature, always get in touch with your dealer or an
authorized HITACHI power tool repair shop when assembling, disassembling or replacing parts
other than accessories or carbon brushes.
* Clean the exterior of the tool with a soft cloth moistened in soap water, and dry thoroughly.
Don’t use chloric solvents, gasoline or thinner on plastic components; otherwise they might
dissolve.
