against safety hazards, the dangers inherent in the use of any electric power tool cannot be completely

eliminated. Accordingly, general precautions and suggestions for the use of electric power tools, and

specific precautions and suggestions for the use of the Cutters are listed in the Handling Instructions to

Salespersons must be thoroughly familiar with the contents of the Handling Instructions to be able to offer

appropriate guidance to the customer during sales promotion.

B. Caution on name plate

Each tool is provided with a Name Plate which contains the following basic safety precautions in the use of

the tool.
