GENERAL SAFETY RULES
WARNING!
Read all instructions
Failure to follow all instructions listed below may result in
electric shock, fi re and/or serious injury.
The term “power tool” in all of the warnings listed below
refers to your mains operated (corded) power tool or battery
operated (cordless) power tool.
SAVE THESE INSTRUCTIONS
1) Work area
a) Keep work area clean and well lit.
Cluttered and dark areas invite accidents.
b) Do not operate power tools in explosive
atmospheres, such as in the presence of
fl ammable liquids, gases or dust.
Power tools create sparks which may ignite the dust
of fumes.
c) Keep children and bystanders away while
operating a power tool.
Distractions can cause you to lose control.
2) Electrical safety
a) Power tool plugs must match the outlet.
Never modify the plug in any way.
Do not use any adapter plugs with earthed
(grounded) power tools.
Unmodifi ed plugs and matching outlets will reduce
risk of electric shock.
b) Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges and
refrigerators.
There is an increased risk of electric shock if your
body is earthed or grounded.
c) Do not expose
power tools to rain or wet
conditions.
Water entering a power tool will increase the risk
of electric shock.
d) Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the power tool.
Keep cord away from heat, oil, sharp edges or
moving parts.
Damaged or entangled cords increase the risk of
electric shock.
e) When operating a power tool outdoors, use an
extension cord suitable for
outdoor use.
Use of a cord suitable for outdoor use reduces
the risk of electric shock.
3) Personal safety
a) Stay alert, watch what you are doing and use
common sense when operating a power tool.
Do not use a power tool while you are tired
or under the infl uence of drugs, alcohol or
medication.
A moment of inattention while operating power
tools may result in serious personal injury.
b) Use safety equipment. Always wear eye
protection.
Safety equipment such as dust mask, non-skid
safety shoes, hard hat, or hearing protection used for
appropriate conditions will reduce personal injuries.
c) Avoid accidental starting. Ensure the switch is in
the off position before plugging in.
Carrying power tools with your fi nger on the
switch or plugging in power tools that have the switch
on invites accidents.
d) Remove any adjusting key or wrench before
turning the power tool on.
A wrench or a key left attached to a rotating part
of the power tool may result in personal injury.
e) Do not overreach. Keep proper footing and
balance at all times.
This enables better control of the power tool in
unexpected situations.
f) Dress properly. Do not
wear loose clothing or
jewellery. Keep your hair, clothing and gloves
away from moving parts.
Loose clothes, jewellery or long hair can be caught in
moving parts.
g) If devices are provided for the connection of
dust extraction and collection facilities, ensure
these are connected and properly used.
Use of these devices can reduce dust related
hazards.
4) Power tool use and care
a) Do not force the power tool. Use
the correct
power tool for your application.
The correct power tool will do the job better and safer
at the rate for which it was designed.
b) Do not use the power tool if the switch does not
turn it on and off .
Any power tool that cannot be controlled with the
switch is dangerous and must be repaired.
c) Disconnect the plug from the power source
before making any adjustments, changing
accessories, or storing power tools.
Such preventive safety measures reduce the risk
of starting the power tool accidentally.
d) Store idle power tools
out of the reach of children
and do not allow persons unfamiliar with the
power tool or these instructions to operate the
power tool.
Power tools are dangerous in the hands of untrained
users.
e) Maintain power tools. Check for misalignment or
binding of moving parts, breakage of parts and
any other condition that may aff ect the power
tools’ operation.
If damaged, have the power tool repaired before
use.
Many accidents are caused by poorly maintained
power tools.
f) Keep cutting tools sharp and clean.
Properly maintained cutting tools with sharp cutting
edges are less likely to bind and are easier to
control.
g) Use the power tool, accessories and tool bits
etc., in accordance with these instructions and
in the manner intended for the particular type
of power tool, taking into account the working
conditions and the work to be performed.
Use of the power tool for operations diff erent from
intended could result in a hazardous situation.
5) Service
a) Have your power tool serviced by a qualifi ed
repair person using only identical replacement
parts.
This will ensure that the safety of the power tool
is maintained.
PRECAUTION
Keep children and infi rm persons away.
When not in use, tools should be stored out of reach of
children and in
fi rm persons.

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. Grounding
This tool should be grounded while in use to protect the
operator from electric shock. The tool is equipped with a
three conductor cord and grounding type
plug to fi t the
proper grounding type receptacle. The green (or green
and yellow) conductor in the cord is the grounding wire.
Never connect the green (or green and yellow) wire to a
live terminal.

3. 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.
4. 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.
5. Confi rming condition of the environment
Confi rm that the work site is placed under appropriate
conditions conforming to prescribed precautions.
When grinding
a thin steel plate, depending upon the
state of the workbench, a loud noise will be created due
to resounding noise from the steel plate being ground. To
eliminate unwanted noise in this instance, place a rubber
mat beneath the material to be ground.
6. Mounting the wheel guard
Be sure
to mount the wheel guard at an angle that will
protect the operator’s body from injury by a broken wheel
piece.
7. Confi rm the lock pin
Confi rm that the lock pin is disengaged by pushing lock
pin two or three times before switching the power tool
on.
8. Confi
rming and mounting the depressed center
wheel.
Thoroughly check that a specifi ed depressed center
wheel is free of cracks and splits is mounted.
Confi rm that the depressed center wheel is mounted
under the specifi ed condition and is fi rmly clamped.
For details, refer to the item “Assembling and
Disassembling the depressed center wheel.”
9. Apply a trial run
To start grinding work without checking for possible
cracks and splits in the depressed center wheel is very
dangerous. Prior to start of grinding, direct the grinder
in a direction where no one is present, and apply a trial
run without
fail to confi rm that the grinder displays no
abnormalities.
Duration of the trial run is as follows:
When depressed center wheels is replaced
........................................................ 3 minutes or more
When starting daily work ...................1 minute or more
PRACTICAL GRINDER APPLICATION
1. Since grinding by utilizing only the grinder’s own weight
is feasible, the grinder should never be pressed forcibly
against the plane to be ground. Hold the grinder lightly so
that it only slightly contacts the plane to be ground.
Heavy pressure will reduce the revolving speed and
such deteriorate the
fi nished surface, and phenomena as
overload will lead to burning out of the motor.
2. Do not utilize the grinder entire surface when grinding.
Use only its peripheral surface by tilting the wheel at an
angle of 15°–30°, as shown in Fig. 1.
3. When a grinder equipped with a new
depressed center
wheel is pushed forward (direction A), the wheel edge
may occasionally cut into the material to be ground.
Always pull it backward (direction B) in this instance.
However, once the depressed center wheel angle has
been adequately abraded, both forward and backward
operations are permissible.
4. The provided depressed
center wheel (resinoid wheel) is
rated as Class A grain and #36 grain size.
Accordingly, its range of applications cover a wide
variety, proving to be most suitable for heavy grinding
of general steel materials. Since the wheel grain size
is rather coarse, creating a fi ne-surfaced fi nish is very
diffi cult.
In this instance, hold the grinder lightly as through trying
to lift it,
and apply grinding slowly at a constant low speed.
Whereby a fi ne fi nish similar to that accomplished with a
fi ne-grain depressed center wheel is obtainable.
5. Switching on the grinder
The switch can be turned ON by turning its lever ON side,
or turn OFF by turning its lever to
the OFF side.
6. Precaution after use
Do not lay the grinder down immediately after use in a
place where there are many shavings and much dirt and
dust until it has completely stopped revolving.
CAUTION
○ Shock to the main body can be the cause of cracks or
splits in the depressed
center wheel. Be especially careful
to avoid sudden shocks when using the equipment.
If the main unit is accidentally bumped or dropped, make
a careful check for cracks or splits on the depressed
center wheel before further use.
○ Do not press the lock pin when the equipment is turning.
Also,
do not turn on the switch when the lock pin is
pressed down.
ASSEMBLING AND DISASSEMBLING
THE DEPRESSED CENTER WHEEL (Fig. 2)

size diamond wheel. (external dia.
105 mm, internal dia. 20 mm)
(2) Do not apply cooling water or grinding fl uid while utilizing
the diamond wheel.
(3) Hold the tool fi rmly to control the tendency of the tool to
be repelled by the material during cutting operation.
(4) Ensure that the cutting depth
is kept within 2–5 mm
to prevent over-heating damage to the motor. Use with
moderate cutting speed, and do not apply excessive
pressure on the workpiece.
○ Mounting the Guide Base Assembly. (Fig. 4)
(1) Loosen the two small screws on the wheel guard.
(2) Insert the guide piece between the wheel
guard and set
plate (A), and tighten one of the small screws. Ensure
that the guide will not move.
(3) Set the angle of the wheel guard to a suitable position
for operation, and securely tighten the remaining small

in Fig. 5. Note that the wheel washer is reversed from
ordinary usage with depressed center wheel.
(1) Mount the wheel washer and diamond wheel onto the
spindle.
(2) Mount the concave side of the wheel nut onto the
diamond
wheel, and screw the wheel nut onto the spindle.
(3) As shown in Fig. 5 push in the lock pin to prevent rotation
of the spindle. Then, secure the diamond wheel by
tightening the wheel nut with the wrench.
MAINTENANCE AND INSPECTION
1. Inspecting the depressed center wheel
Ensure that the depressed center wheel is free of cracks
and surface defects.
Replace the depressed center wheel when it has been
worn out to about 60 mm in external diameter.
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. Failure to do so could
result in serious hazard.
3. 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.
4. Inspecting the carbon brushes (Fig. 8)
The motor employs carbon brushes that are consumable
parts. Since an excessively worn carbon brush can result
in motor trouble, replace the carbon brush with a new
one having the same carbon brush No. shown in the
fi gure
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.
5. Replacing carbon brushes
Disassemble the brush caps with a slotted-head
screwdriver. The carbon brushes can then be easily
removed.
