High-power motor

The Models G 10SR2, G 12SR2 and G 13SR2 are equipped with high-power motors and are more powerful

than the current Models G 10SR, G 12SR and G 13SR although they are compact and lightweight. We could

say that the ratio of the motor's maximum output to the product's weight defines its performance. Compared

with a typical competitor's model in terms of this indicator, the Models G 10SR2, G 12SR2 and G 13SR2 prove

to have the highest performance.

6-2. Practical Test Data

Comparison of temperature rise of stator coil section:

The graph below shows the relationship between load and temperature rise of stator coil. The temperature rise of

the Models G 10SR2, G 12SR2 and G 13SR2 is the lowest among similar models. This means that the

resistance to overload usage of the Models G 10SR2, G 12SR2 and G 13SR2 is superior to other models.

7. PRECAUTIONS IN SALES PROMOTION

In the interest of promoting the safest and most efficient use of the Models G 10SR2, G 12SR2 and G 13SR2 Disc

Grinders by all of our customers, it is very important that at the time of sale, the salesperson carefully ensures that

the buyer seriously recognizes the importance of the contents of the Handling Instructions, and fully understands

the meaning of the precautions listed on the Name Plate or Caution Plate attached to each tool.

7-1. 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, general precautions and suggestions for the use of electric power tools, and specific precautions and

suggestions for the use of the disc grinders are listed in the Handling Instructions to enhance the safe and efficient

use of the tool by the customer. 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.

7-2. 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.

(1) For European countries

(2) For U.S.A. and Canada

WARNING

To reduce the risk of injury, user must read and understand instruction manual.

Always use proper guards when grinding and wear eye protection.

Use only accessories rated at least * /min.

AVERTISSEMENT

Afin de reduire le risque de blessures, I'utilisateur doit lire et bien comprendre le mode d'emploi.

Utilisez toujours un outil muni d'un protecteur adequat et portez des lunettes on une visiere.

N'utilisez que des accessoires prevus pour au moins * /min.

7-3. Precautions on Usage

(1) The wheel guard must be aligned in relation to the side handle mounting position.

As illustrated in Figs. 5 and 6, the customer should be instructed that the wheel guard mounting angle must be

aligned and fixed in accordance with the side handle mounting position so that the operator's hand will not

contact the depressed center wheel.

Fig. 5 Fig. 6

(2) Never press the pushing button while the depressed center wheel is rotating.

If the pushing button is pressed while the depressed center wheel is rotating, the spindle will stop immediately.

In such a case, there is a danger that the wheel nut may be loosened so that the depressed center wheel flies

off unexpectedly to cause possible serious injury.
