GENERAL OPERATIONAL PRECAUTIONS
WARNING! When using electric tools, basic safety
precautions should always be followed to reduce the risk
of fire, electric shock and personal injury, including the
following.
Read all these instructions before operating this product
and save these instructions.
For safe operations:
1. Keep work area clean. Cluttered areas and benches
invite injuries.
2. Consider work area environment. Do not expose
power tools to rain. Do not use power tools in
damp or wet locations. Keep work area well lit.
Do not use power tools where there is risk to
cause fire or explosion.
3. Guard against electric shock. Avoid body contact

PRECAUTIONS ON USING DISC GRINDER
1. Never operate these power tools without Wheel
Guards.
2. Use only a depressed center wheel 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. Otherwise the counterforce
produced may result in inaccurate and even
dangerous operation.
4. Do not work near welding equipment.
If you work near welding equipment, rotation may
become unstable.
5. Ensure that blotters are used when they are
provided with the bonded abrasive product and
when they are required.
6. Ensure that sparks resulting from use do not create
a hazard e.g. do not hit persons, or ignite flammable
substances.
7. Do not use separate reducing bushings or adaptors
to adapt large hole abrasive wheels.

Standard accessories are subject to change without
notice.
6. Conducting a trial run
Before commencing grinding operation, the ma-
chine should be given a trial run in a safe area to
ensure that it is properly assembled and that the
depressed center wheel is free from obvious de-
fects.
Recommended trial runs'duration are as follows:
After replacing depressed center wheel
........................................... 3 minutes or more
Prior to starting routine work
............................................ 1 minute or more
7. Confirm the lock pin.
Confirm that the lock pin is disengaged by pushing
lock pin two or three times before switching the
power tool on (See Fig. 2).
3. 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
first class finish, 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 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.
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 con-
ducted in either direction.
4. Precautions immediately after finishing 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 acci-
dents, this precaution will reduce the amount of
dust and swarf sucked into the machine.
APPLICATIONS
Removal of casting fin and finishing 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 con-
forms to the power requirements specified 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 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. By slightly loosening the setting screw,
the wheel guard can be turned and set at any
desired angle for maximum operational effective-
ness. 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 “Depressed Center
Wheel Assembly”

English
CAUTION
When the machine is not in use, the power source
should be disconnected.
ASSEMBLING AND DISASSEMBLING THE
DEPRESSED CENTER WHEEL (Fig. 2)
CAUTION: Be sure to switch OFF and disconnect the
attachment plug from the receptacle to avoid
a serious accident.
1. Assembling (Fig. 2)
(1) Turn the equipment upsidedown so that the
spindle will be facing up.
(2) Mount the wheel washer onto the spindle.
(3) Fit the protuberance of the depressed center wheel
onto the wheel washer.
(4) Screw from above the wheel nut onto the spindle.
(5) As shown in Fig. 2, push in the lock pin to
prevent rotation of the spindle. Then, secure the
depressed center wheel by tightening the wheel
nut with the wrench.
2. Disassembling
Follow the above procedures in reverse.
CAUTIONS:
Comfirm that the depressed center wheel is mounted
firmly.
Confirm that the lock pin is disengaged by pushing
lock pin two or three times before switching the
power tool on.
MAINTENANCE AND INSPECTION
1. Inspecting the depressed center wheel
Ensure that the depressed center wheel is free of
cracks and surface defects.
2. Inspecting the mounting screws:
Regularly inspect all mounting screws and ensure
that they are properly tightened. Should any of the
screws be loose, retighten them immediately. Fail-
ure to do so could result in serious hazard.
3. Inspecting the carbon brushes (Fig. 3)
The motor employs carbon brushes which are
consumable parts. Since an excessively worn car-
bon brush can result in motor trouble, replace the
carbon brush with a new one having the same
carbon brush No. shown in the figure when it
becomes worn to or near the wear limit. In
addition, always keep carbon brushes clean and
ensure that they slide freely within the brush holders.
4. Replacing carbon brushes:
Disassemble the brush caps with a slotted-head
screwdriver. The carbon brushes can then be easily
removed.
5. Maintenance of the motor
The motor unit winding is the very heart of the
power tool. Exercise due care to ensure the winding
does not become damaged and/or wet with oil or
water.
