PRECAUTIONS
ON USING
DISC GRINDER
1. Never operate
these power tools without Wheel
Guards.
2. Use only grinding wheels with a “Safe Speed” of
at least as high as the “No-Load RPM” indicated
on the power tool nameplate.
3. Always hold the body handle and side handle of
the power tool firmly.
Otherwirse the counterforce produced may result in inaccurate and even

APPLICATIONS
0
Removal of casting fin and finishing of various
types of steel, bronze and aluminum materials and
castings.
0 Grinding of welded sections or sections cut by
means of a cutting torch.
0 Grinding of synthetic resins, slate, brick, marble,
etc.
o 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.
2.
Ensure that the setting screw is thoroughly tightened after adjusting the wheel guard.
5. Ensure that the grinding wheel to be utilized is the
correct type and free of cracks or surface defects.
Also ensure that the grinding wheel is properly
mounted and the wheel nut is securely tightened.
Refer to the section on “Grinding Wheel Assembly”.
6. Conducting a trial run
Before
commencing
grinding
operation,
the
machine should be given a trial run in a safe area
to ensure that it is properly assembled and that the
grinding wheel is free from obvious defects.
Recommended
trial run durations are as follows:
After replacing grinding wheel
..*..............................
3 minutes or more
Prior to starting routine work
. . . . . . . . . . . . . . . . . ..*............. 1 minutes or more
7. Confirm the spindle lock mechanism.
Confirm that the spindle lock is disengaged
by
pushing push button two or three times before
switching the power tool on (See Fig. 1)
8. Fixing the side handle.
Screw the side handle into the gear cover.
PRACTICAL
To prolong the life of the machine and ensure a
first class finish, it is important that the machine
should not be overloaded by applying too much
In most applications,
the weight of the
pressure.
machine alone is sufficient for effective grinding.
Too much pressure will result in reduced rotational
speed,
inferior surface finish, and overloading
which could reduce the life of the machine.
Power switch
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 grinding wheel shatter during
operation.
Ensure that the guard is properly fitted
and fastened before commencing grinding operation.
By slightly loosening the setting screw, the
wheel guard can be turned and set at any desired
angle for maximum
operational
effectiveness.
APPLICATION
1. Pressure
Ensure that the power switch is in the OFF position. If the plug is connected to a power receptacle while the power switch is in the ON position,
the power tool will start operating immediately,
which could cause a serious accident.
3.
GRINDER
2.
Grinding angle
l
Do not apply the entire surface of the grinding
wheel to the material to be ground.
As shown in
Fig. 2, the machine should be held at an angle of
15“-30’ so that the external edge of the grinding
wheel contacts the material at an optimum angle.
3. To prevent a new grinding wheel from digging into
the workpiece,
initial grinding should be performed by drawing the grinder across the workpiece
toward the operator (Fig. 2 direction B). Once
the leading edge of the grinding wheel is properly
abraded,
grinding may be conducted
in either
direction.
