APPLICATIONS

⅜

of steel, bronze and aluminum materials and castings.

⅜ Grinding of welded sections or sections cut by

means of a cutting torch.

⅜ Grinding of synthetic resins, slate, brick, marble, etc.

⅜ Cutting of synthetic concrete, stone, brick, marble,

and similar materials.

PRIOR TO OPERATION

1. Power source

Ensure that the power source to be utilized conforms

to the power requirements specified on the product

nameplate.

CAUTION:

Do not operate on Direct Current power source.

2. Power switch

Ensure that the power switch is in the OFF position.

If the plug is connected to a receptacle while the

power switch is in the ON position, the power tool

will start operating immediately, which could cause

a serious accident.

3. Extension cord

When the work area is removed from the power

source, use an extension cord of sufficient thickness

and rated capacity. The extension cord should be

kept as short as practicable.

4. Fitting and adjusting the wheel guard

The wheel guard is a protective device to prevent

injury should the depressed center wheel shatter

during operation. Ensure that the guard is properly

fitted and fastened before commencing grinding

operation.

[How to attach and adjust the wheel guard]

〈G13YC〉

By slightly loosening the setting screw, the wheel

guard can be turned and set at any desired angle

for maximum operational effectiveness. Ensure that

the setting screw is thoroughly tightened after

adjusting the wheel guard.

〈G15YC〉 (Fig. 2)

⅜

Set the wheel ass’y to the packing gland.

⅜

Tighten M5 screw to secure the wheel guard while

the lever is in closed position.

⅜

Perform the adjustment of the wheel guard while the

lever is released. (Loosen M5 screw and readjust if

the wheel guard does not rotate smoothly.)

⅜

After adjustment, if machine operation is required,

perform the operation only after setting the lever in

closed position.

⅜

Lubricate the sliding section of the set piece (B) and

the lever if the lever does not move smoothly.

PRECAUTIONS ON USING DISC GRINDER

1. Never operate these power tools without Wheel

Guards.

2. Check that speed marked on the wheel is equal to

or greater than the rated speed of the grinder.

Use only depressed center wheels rated at 80m/s

or more.

3. 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.

4. Never depress the push button while the spinble

is turning.

5. Do not work near welding equipment!

If you work near welding equipment, rotation may

become unstable.

6. Overload protection circuit operation.

If an overload or abnormal load is applied, the

overload protection circuit operates and stops

rotation, so please immediately stop applying load.

Following this, switching the power OFF and then

ON again, will cause the rotation to increase to the

regular speed.
