PRECAUTIONS ON SALES PROMOTION

1. Safety Instructions

In the interest of promoting the safest and most efficient use of the Models G 12VA, G 13VA, G 13YF,
G 15VA and G 15YF Electronic Disc Grinders by all of our customers, it is very important that when
concluding a sale that the salesperson carefully ensure that the buyer seriously recognizes the importance
of the Handling Instructions, and fully understands the precautions listed on the Name Plate or Caution
Plate attached to each tool.
A. Handling instructions
Although every effort is made in each step of design, manufacture, and inspection to provide protection
against safety hazards, the dangers inherent in the use of any electric power tool cannot be completely
eliminated. Accordingly, the Handling Instructions list general precautions and suggestions on the use of
electric power tools, and specific precautions and suggestions on the use of the disc grinders in order to
enhance the safe, efficient use of the tools by the customer.
Salespersons must be thoroughly familiar with the contents of the Handling Instructions in order to offer
appropriate guidance to customers during sales promotion activities.
(1) Checking the power source voltage
Ensure that the power source voltage complies with the power specifications listed on the Name Plate.
Never operate the Models G 12VA, G 13VA, G 13YF, G 15VA and G 15YF using a direct current (DC)
power source. The control circuit in these tools functions through a phase-control system utilizing a triac,
and will not function under the application of DC power.
Any subsequently uncontrolled increase in motor rotation speed could be extremely hazardous.
Do not operate these tools from an engine generator, booster or any other type of transformer. Doing so
may not only damage the grinder, but may also lead to accidents.
NOTE: When the tool is connected to the power supply, the built-in electronic control circuit shifts
to standby status and the grinder becomes slightly warm, though not a malfunction.
B. Caution on Name Plate
Each tool is provided with a name plate that contains the following basic safety precautions on use of the
tool.
