SAFETY WARNINGS COMMON FOR
GRINDING OPERATIONS
a) This power tool is intended to function as a grinder.
Read all safety warnings, instructions, illustrations
and specifications provided with this power tool.
Failure to follow all instructions listed below may result in
electric shock, fire and/or serious injury.
b) Operations such as sanding, wire brushing or
polishing are not recommended to be performed
with this power tool.
Operations for which the power tool was not designed
may create a hazard and cause personal injury.
c) Do not use accessories which are not specifically
designed and recommended by the tool
manufacturer.
Just because the accessory can be attached to your
power tool, it does not assure safe operation.
d) The rated speed of the accessory must be at least
equal to the maximum speed marked on the power
tool.
Accessories running faster than their rated speed can
break and fly apart.
e) The outside diameter and the thickness of your
accessory must be within the capacity rating of
your power tool.
Incorrectly sized accessories cannot be adequately
guarded or controlled.
f) The arbour size of wheels, sanding drums or any
other accessory must properly fit the spindle or
collet of the power tool.
Accessories that do not match the mounting hardware of
the power tool will run out of balance, vibrate excessively
and may cause loss of control.
g) Mandrel mounted wheels, sanding drums, cutters
or other accessories must be fully inserted into the
collet or chuck.
If the mandrel is insufficiently held and/or the overhang
of the wheel is too long, the mounted wheel may become
loose and be ejected at high velocity.
h) Do not use a damaged accessory. Before each use
inspect the accessory such as abrasive wheels for
chips and cracks, backing pad for cracks, tear or
excess wear, wire brush for loose or cracked wires.
If power tool or accessory is dropped, inspect for
damage or install an undamaged accessory. After
inspecting and installing an accessory, position
yourself and bystanders away from the plane of
the rotating accessory and run the power tool at
maximum no-load speed for one minute.
Damaged accessories will normally break apart during
this test time.
i) Wear personal protective equipment. Depending
on application, use face shield, safety goggles or
safety glasses. As appropriate, wear dust mask,
hearing protectors, gloves and workshop apron
capable of stopping small abrasive or workpiece
fragments.
The eye protection must be capable of stopping flying
debris generated by various operations. The dust mask
or respirator must be capable of filtrating particles
generated by your operation. Prolonged exposure to
high intensity noise may cause hearing loss.
j) Keep bystanders a safe distance away from work
area. Anyone entering the work area must wear
personal protective equipment.
Fragments of workpiece or of a broken accessory may
fly away and cause injury beyond immediate area of
operation.
k) Hold the power tool by insulated gripping surfaces
only, when performing an operation where the
cutting accessory may contact hidden wiring.
Cutting accessory contacting a “live” wire may make
exposed metal parts of the power tool “live” and could
give the operator an electric shock.
l) Always hold the tool firmly in your hand(s) during
the start-up.
The reaction torque of the motor, as it accelerates to full
speed, can cause the tool to twist.
m) Use clamps to support workpiece whenever
practical. Never hold a small workpiece in one hand
and the tool in the other hand while in use.
Clamping a small workpiece allows you to use your
hand(s) to control the tool. Round material such as
dowel rods, pipes or tubing have a tendency to roll while
being cut, and may cause the bit to bind or jump toward
you.
n) Never lay the power tool down until the accessory
has come to a complete stop.
The spinning accessory may grab the surface and pull
the power tool out of your control.
o) After changing the bits or making any adjustments,
make sure the collet nut, chuck or any other
adjustment devices are securely tightened.
Loose adjustment devices can unexpectedly shift,
causing loss of control, loose rotating components will
be violently thrown.
p) Do not run the power tool while carrying it at your
side.
Accidental contact with the spinning accessory could
snag your clothing, pulling the accessory into your body.
q) Regularly clean the power tool’s air vents.
The motor’s fan will draw the dust inside the housing and
excessive accumulation of powdered metal may cause
electrical hazards.
r) Do not operate the power tool near flammable
materials.
Sparks could ignite these materials.
s) Do not use accessories that require liquid coolants.
Using water or other liquid coolants may result in
electrocution or shock.

KICKBACK AND RELATED
WARNINGS
Kickback is a sudden reaction to a pinched or snagged
rotating wheel, backing pad, brush or any other accessory.
Pinching or snagging causes rapid stalling of the rotating
accessory which in turn causes the uncontrolled power tool
to be forced in the direction opposite of the accessory’s
rotation at the point of the binding.
For example, if an abrasive wheel is snagged or pinched by
the workpiece, the edge of the wheel that is entering into the
pinch point can dig into the surface of the material causing
the wheel to climb out or kick out. The wheel may either jump
toward or away from the operator, depending on direction of
the wheel’s movement at the point of pinching.
Abrasive wheels may also break under these conditions.
Kickback is the result of power tool misuse and/or incorrect
operating procedures or conditions and can be avoided by
taking proper precautions as given below.
a) Maintain a firm grip on the power tool and position
your body and arm to allow you to resist kickback
forces.
The operator can control kickback forces, if proper
precautions are taken.
b) Use special care when working corners, sharp
edges etc. Avoid bouncing and snagging the
accessory.
Corners, sharp edges or bouncing have a tendency to
snag the rotating accessory and cause loss of control or
kickback.
c) Do not attach a toothed saw blade.
Such blades create frequent kickback and loss of
control.
d) Always feed the bit into the material in the same
direction as the cutting edge is exiting from the
material (which is the same direction as the chips
are thrown).
Feeding the tool in the wrong direction causes the cutting
edge of the bit to climb out of the work and pull the tool in
the direction of this feed.
e) When using rotary files, cut-offwheels, high-speed
cutters or tungsten carbide cutters, always have
the work securely clamped.
These wheels will grab if they become slightly canted
in the groove, and can kickback. When a cut-offwheel
grabs, the wheel itself usually breaks. When a rotary file,
high-speed cutter or tungsten carbide cutter grabs, it
may jump from the groove and you could lose control of
the tool.
SAFETY WARNINGS SPECIFIC FOR
GRINDING AND ABRASIVE CUTTING-
OFF OPERATIONS
a) Use only wheel types that are recommended
for your power tool and only for recommended
applications. For example: do not grind with the
side of a cut-offwheel.
Abrasive cut-offwheels are intended for peripheral
grinding, side forces applied to these wheels may cause
them to shatter.
b) For threaded abrasive cones and plugs use only
undamaged wheel mandrels with an unrelieved
shoulder flange that are of correct size and length.
Proper mandrels will reduce the possibility of breakage.
c) Do not “jam” a cut-offwheel or apply excessive
pressure. Do not attempt to make an excessive
depth of cut.
Overstressing the wheel increases the loading and
susceptibility to twisting or snagging of the wheel in the
cut and the possibility of kickback or wheel breakage.
d) Do not position your hand in line with and behind
the rotating wheel.
When the wheel, at the point of operation, is moving
away from your hand, the possible kickback may propel
the spinning wheel and the power tool directly at you.
e) When wheel is pinched, snagged or when
interrupting a cut for any reason, switch offthe
power tool and hold the power tool motionless until
the wheel comes to a complete stop. Never attempt
to remove the cut-offwheel from the cut while the
wheel is in motion otherwise kickback may occur.
Investigate and take corrective action to eliminate the
cause of wheel pinching or snagging.
f) Do not restart the cutting operation in the workpiece.
Let the wheel reach full speed and carefully re-enter
the cut.
The wheel may bind, walk up or kickback if the power
tool is restarted in the workpiece.
g) Support panels or any oversized workpiece to
minimize the risk of wheel pinching and kickback.
Large workpieces tend to sag under their own weight.
Supports must be placed under the workpiece near the
line of cut and near the edge of the workpiece on both
sides of the wheel.
h) Use extra caution when making a “pocket cut” into
existing walls or other blind areas.
The protruding wheel may cut gas or water pipes,
electrical wiring or objects that can cause kickback.
GENERAL SAFETY INSTRUCTIONS
FOR CORDLESS GRINDER

and free of cracks or surface defects. Also ensure that
the wheel is properly mounted and the collet chuck is
securely tightened.
2. 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.
3. The wheel continues to rotate after the tool is switched
off.
After switching offthe machine, do not put it down until
the 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.
4. Be careful of brake kickback.
This cordless die grinder features an electric brake that
functions when the switch is released. As there is some
kickback when the brake functions, be sure to hold the
main body securely.

NOTE
The recharging time may vary according to the ambient
temperature and power source voltage.
CAUTION
When the battery charger has been continuously used,
the battery charger will be heated, thus constituting
the cause of the failures. Once the charging has been
completed, give 15 minutes rest until the next charging.
4. Disconnect the charger’s power cord from the
receptacle.
5. Hold the charger firmly and pull out the battery.
NOTE
Be sure to pull out the battery from the charger after use,
and then keep it.
Regarding electric discharge in case of new batteries,
etc.
As the internal chemical substance of new batteries and
batteries that have not been used for an extended period
is not activated, the electric discharge might be low when
using them the first and second time. This is a temporary
phenomenon, and normal time required for recharging
will be restored by recharging the batteries 2–3 times.
How to make the batteries perform longer.
(1) Recharge the batteries before they become completely
exhausted.
When you feel that the power of the tool becomes
weaker, stop using the tool and recharge its battery. If
you continue to use the tool and exhaust the electric
current, the battery may be damaged and its life will
become shorter.
(2) Avoid recharging at high temperatures.
A rechargeable battery will be hot immediately after
use. If such a battery is recharged immediately after
use, its internal chemical substance will deteriorate, and
the battery life will be shortened. Leave the battery and
recharge it after it has cooled for a while.
CAUTION
○If the battery is charged while it is heated because it has
been left for a long time in a location subject to direct
sunlight or because the battery has just been used,
the pilot lamp of the charger lights up green or lights
for 1 second, does not light for 0.5 seconds (offfor
0.5 seconds). In such a case, first let the battery cool,
then start charging.
00BookGP18DAUK.indb1100BookGP18DAUK.indb11 2021/03/0415:38:112021/03/0415:38:11

○When the pilot lamp flickers in red (at 0.2-seconds
intervals), check for and take out any foreign objects in
the charger’s battery connector. If there are no foreign
objects, it is probable that the battery or charger is
malfunctioning. Take it to your authorized Service
Center.
○Since the built-in micro computer takes about 3 seconds
to confirm that the battery being charged with chargers
are taken out, wait for a minimum of 3 seconds before
reinserting it to continue charging. If the battery is
reinserted within 3 seconds, the battery may not be
properly charged.

*1 Installing a wheel (Fig. 5)
Install the wheel so that length ℓis less than 15 mm. If ℓ
is longer, abnormal vibration will occur, and the machine
is not only negatively affected, but there is a possibility of
a serious accident.
Make the ℓas small as possible.
When d = 6 mm, 1/4", 8 mm, D of the wheel should be
less than the Max. wheel diameter (50 mm). If a wheel
with D more than the Max. wheel diameter (50 mm) is
used, the circumference speed exceeds the safety limit
and the wheel will break. Never use such a wheel.
Distance L varies for D. Determine L referring to the
Table 3.
When d = 3 mm, 1/8", D should be less than 10 mm.
Determine L referring to the Table 3.
Wheels can be simply attached and detached by using
the two wrenches. (Fig. 6)
NOTE
○Do not tighten the collet chuck by inserting a shaft thinner
than the regular shaft diameter (6 mm) in the chuck or in
an empty condition. This practice will damage the collet
chuck.
○When using a shaft (3 mm), switch to a collet chuck for
3 mm shaft (sold separately). (Fig. 4)
○When installing a wheel with shaft, tighten the collet
chuck after applying a small quantity of spindle oil (or
sewing machine oil) to the tapered portion. (Fig. 5)

*2 Using the side handle
Install the side handle after removing the front cover.
Detach the front cover by removing the protrusion on
the interior from the hollow in the main unit and pull to
remove. If the protrusion is difficult to detach, use a flat-
head screwdriver or similar tool.
*3 Dial of variable speed operation
The unit has “Transmission mode” and “Auto mode”.
○With Transmission mode, the grinder’s number of
revolutions can be set at one of five stages.
When operating in Transmission mode, the set number
of revolutions will be maintained regardless of changes
in load.
○With Auto mode, you can lower noise and vibration by
lowering the maximum number of revolutions while in a
no-load state.
While in Auto mode, the number of revolutions will be
raised if the load becomes greater during operation.
On the other hand, the number of revolutions will be
lowered if the load decreases during operation. (Table 4)
○Set the mode and dial according to work application.

Caution when using near welding equipment
When using the grinder in the immediate vicinity of
welding equipment, the rotational speed may become
unstable. Do not use the grinder near welding equipment.
Precautions on operation
(1) Lightly press the wheel to the material to be ground.
When grinding materials, high-speed revolution is
necessary. Use a die grinder with high-speed revolution,
minimizing the pressing force.
CAUTION
When using the tool at any value except the full speed
(Dial scale 5), the motor cannot be sufficiently cooled
due to the decreased number of revolution. This could
result in the risk of burning and damaging the motor
before an overload protective mechanism starts to
function.
Make sure that you use the tool by lightly applying it
to the surface of material when you use it at any value
except the full speed (Dial scale 5).
(2) Dressing the wheel
After attaching a wheel, correct deflection of the wheel
center by using a dresser. If the wheel center is eccentric,
not only precise finishing cannot be achieved but also
grinder vibration increases, lowering grinder accuracy
and durability.
A clogged or worn wheel will spoil the finishing surface or
lower grinding efficiency. Occasionally dress the wheel
by applying the dresser.
WHEEL SELECTING METHOD
Types of wheels are varied according to the materials to be ground. Select a wheel appropriate for the material to be ground.
The following table is an outline of wheels and materials to be ground.
Materials to be ground Grain Grading Bonding degree Structure Bonding agent
Mild steel, hard steel,
forged steel WA 60–80 P m V
Cast iron C 36 M–O m V
Brass, bronze, aluminium C 36 J–K m V
Ceramic WA 60–80 M m V
Synthetic resin C 36 K–M m V
Small-scaled wheels with shaft are prepared for grinding small surfaces. Their dimensions and shapes are shown in
“Selecting accessories”.
Since wheel shaft diameter is 3 mm, use the collet chuck for 3 mm shaft sold separately by your HiKOKI dealer as an
optional accessory.
MAINTENANCE AND INSPECTION
WARNING
Be sure to turned offthe switch and remove the battery
before maintenance and inspection.
1. Inspecting the wheel
Ensure that the 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. 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. Inspection of terminals (tool and battery)
Check to make sure that swarf and dust have not
collected on the terminals.
On occasion check prior, during and after operation.
CAUTION
Remove any swarf or dust which may have collected on
the terminals.
Failure to do so may result in malfunction.
5. Cleaning on the outside
When the power tool is stained, wipe with a soft dry cloth
or a cloth moistened with soapy water. Do not use chloric
solvents, gasoline or paint thinner, for they melt plastics.
6. Cleaning the filter
After use, detach the filter and remove any grime or dust
from the screen with an airgun or other tool. (Fig. 10)
NOTE
○To clear the unit of grime or dust, periodically run
the motor in a no-load state and blow dry air into the
ventilation hole with the filter removed.
Accumulation of grime or dust accumulates in the motor
can cause damage.
○After cleaning, make sure to securely attach the filter.
7. Storage
Store the power tool in a place in which the temperature
is less than 40°C and out of reach of children.
NOTE
Storing lithium-ion batteries.
Make sure the lithium-ion batteries have been fully
charged before storing them.
Prolonged storage (3 months or more) of batteries with
a low charge may result in performance deterioration,
significantly reducing battery usage time or rendering
the batteries incapable of holding a charge.
However, significantly reduced battery usage time may
be recovered by repeatedly charging and using the
batteries two to five times.
If the battery usage time is extremely short despite
repeated charging and use, consider the batteries dead
and purchase new batteries.
