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.

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.
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.

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)
Set the wheel ass'y to the packing gland.
Tighten M5 screw to secure the wheel guard while
the lever is in closed position.
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.)
After adjustment, if machine operation is required,
perform the operation only after setting the lever in
closed position.
Lubricate the sliding section of the set piece (B) and
the lever if the lever does not move smoothly.
