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.

APPLICATIONS
○ Removal of casting fi n and fi nishing of various types
of steel, bronze and aluminum materials and castings.
○ Grinding of welded sections or sections cut by means
of a cutting torch.
○ Grinding of synthetic resins, slate, brick, marble, etc.
PRIOR TO OPERATION
1. Power source
Ensure that the power source to be utilized conforms
to the power requirements specifi ed on the product
nameplate.
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 suffi cient 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 fi tted 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. Ensure that the
setting screw is thoroughly tightened after adjusting
the wheel guard.
5. Ensure that the depressed center wheel to be utilized
is the correct type and free of cracks or surface
defects. Also ensure that the depressed center wheel
is properly mounted and the wheel nut is securely
tightened. Refer to the section on "ASSEMBLING
AND DISASSEMBLING THE DEPRESSED CENTER
WHEEL".
5
Use only depressed center wheels rated at 80 m/s
(72 m/s only for 100 mm disc grinders) or more.
3. Always hold the body handle and side handle of
the power tool fi rmly. Otherwise the counterforce
produced may result in inaccurate and even
dangerous operation.

6. Conducting a trial run
Ensure that the abrasive products is correctly
mounted and tightened before use and run the tool
at no-load for 30 seconds in a safe position, stop
immediately if there is considerable vibration or if
other defects are detected.
If this condition occurs, check the machine to
determine the cause.
7. Confi rm the push button
Confi rm that the push button is disengaged by
pushing push button two or three times before
switching the power tool on (See Fig. 2).
8. Fixing the side handle
Screw the side handle into the gear cover.
PRACTICAL GRINDER APPLICATION
1. Pressure
To prolong the life of the machine and ensure a fi rst
class fi nish, it is important that the machine should
not be overloaded by applying too much pressure. In
most applications, the weight of the machine alone
is suffi cient for effective grinding.
Too much pressure will result in reduced rotational
speed, inferior surface fi nish, and overloading which
could reduce the life of the machine.
2. Grinding angle
Do not apply the entire surface of the depressed
center wheel to the material to be ground. As shown
in Fig. 1, the machine should be held at an angle of
15° – 30° so that the external edge of the depressed
center wheel contacts the material at an optimum
angle.
3. To prevent a new depressed center wheel from
digging into the workpiece, initial grinding should
be performed by drawing the grinder across the
workpiece toward the operator (Fig. 1 direction B).
Once the leading edge of the depressed center wheel
is properly abraded, grinding may be conducted in
either direction.
4. Precautions immediately after fi nishing operation
After switching off the machine, do not put it
down until the depressed center wheel has come
to a complete stop. Apart from avoiding serious
accidents, this precaution will reduce the amount of
dust and swarf sucked into the machine.
