GENERAL POWER TOOL SAFETY
WARNINGS
WARNING
Read all safety warnings and all instructions.
Failure to follow the warnings and instructions may result in
electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your mains-
operated (corded) power tool or battery-operated (cordless)
power tool.
1) Work area safety
a) Keep work area clean and well lit.
Cluttered or dark areas invite accidents.
b) Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquids, gases or dust.
Power tools create sparks which may ignite the dust
or 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.
Unmodified 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.
f) If operating a power tool in a damp location
is unavoidable, use a residual current device
(RCD) protected supply.
Use of an RCD 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 influence of drugs, alcohol or
medication.
A moment of inattention while operating power tools
may result in serious personal injury.
b) Use personal protective equipment. Always
wear eye protection.
Protective equipment such as dust mask, non-skid
safety shoes, hard hat, or hearing protection used for
appropriate conditions will reduce personal injuries.

children and infirm persons.
SAFETY WARNINGS COMMON FOR
GRINDING OR ABRASIVE CUTTING-
OFF OPERATIONS
a) This power tool is intended to function as a
grinder or cut-offtool. 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) Threaded mounting of accessories must match the
grinder spindle thread. For accessories mounted
by flanges, the arbour hole of the accessory must
fit the locating diameter of the flange.
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) 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.
h) 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.
i) 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.
j) Hold the power tool by insulated gripping surfaces
only, when performing an operation where the
cutting tool may contact hidden wiring.
Contact with a “live” wire will also make exposed metal
parts of the power tool “live” and could give the operator
an electric shock.
k) Position the cord clear of the spinning accessory.
If you lose control, the cord may be cut or snagged
and your hand or arm may be pulled into the spinning
accessory.
l) 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.
m) 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.
n) 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.
o) Do not operate the power tool near flammable
materials.
Sparks could ignite these materials.
p) 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
0000BookG18DBL.indb30000BookG18DBL.indb3 2020/06/1015:04:582020/06/1015:04:58

4
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. Always use auxiliary handle, if provided, for
maximum control over kickback or torque reaction
during start-up.
The operator can control torque reactions or kickback
forces, if proper precautions are taken.
b) Never place your hand near the rotating accessory.
Accessory may kickback over your hand.
c) Do not position your body in the area where power
tool will move if kickback occurs.
Kickback will propel the tool in direction opposite to the
wheel’s movement at the point of snagging.
d) 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.
e) Do not attach a saw chain woodcarving blade or
toothed saw blade.
Such blades create frequent kickback and loss of
control.
SAFETY WARNINGS SPECIFIC FOR
GRINDING AND ABRASIVE CUTTING-
OFF OPERATIONS
a) Use only wheel types that are recommended for
your power tool and the specific guard designed
for the selected wheel.
Wheels for which the power tool was not designed
cannot be adequately guarded and are unsafe.
b) The grinding surface of centre depressed wheels
must be mounted below the plane of the guard lip.
An improperly mounted wheel that projects through the
plane of the guard lip cannot be adequately protected.
c) The guard must be securely attached to the power
tool and positioned for maximum safety, so the
least amount of wheel is exposed towards the
operator.
The guard helps to protect the operator from broken
wheel fragments, accidental contact with wheel and
sparks that could ignite clothing.
d) Wheels must be used only for recommended
applications. For example: do not grind with the
side of cut-offwheel.
Abrasive cut-offwheels are intended for peripheral
grinding, side forces applied to these wheels may cause
them to shatter.
e) Always use undamaged wheel flanges that are of
correct size and shape for your selected wheel.
Proper wheel flanges support the wheel thus reducing
the possibility of wheel breakage. Flanges for cut-off
wheels may be different from grinding wheel flanges.
f) Do not use worn down wheels from larger power
tools.
Wheel intended for larger power tool is not suitable for
the higher speed of a smaller tool and may burst.
ADDITIONAL SAFETY WARNINGS
SPECIFIC FOR ABRASIVE CUTTING-
OFF OPERATIONS
a) Do not “jam” the 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 binding of the wheel in the cut
and the possibility of kickback or wheel breakage.
b) Do not position your body in line with and behind
the rotating wheel.
When the wheel, at the point of operation, is moving
away from your body, the possible kickback may propel
the spinning wheel and the power tool directly at you.
c) When wheel is binding 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 binding.
d) 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.
e) 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.
f) 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 DISC GRINDERS
– Check that speed marked on the wheel is equal to or
greater than the rated speed of the grinder;
– Ensure that the wheel dimensions are compatible with
the grinder;
– Abrasive wheels shall be stored and handled with care in
accordance with manufacturer’s instructions;
– Inspect the grinding wheel before use, do not use
chipped, cracked or otherwise defective products;
– Ensure that mounted wheels and points are fitted in
accordance with the manufacturer’s instructions;
– Ensure that blotters are used when they are provided
with the bonded abrasive product and when they are
required;
– Ensure that the abrasive product 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;
– If a guard is equipped with the tool never use the tool
without such a guard;
– When using an abrasive cutting wheel, be sure to remove
the standard accessory wheel guard and attach the
wheel guard with side guard (sold separately) (Fig. 4);
– Do not use separate reducing bushings or adapters to
adapt large hole abrasive wheels;
– For tools intended to be fitted with threaded hole wheel,
ensure that the thread in the wheel is long enough to
accept the spindle length;

– Check that the work piece is properly supported;
– Do not use cutting offwheel for side grinding;
– Ensure that sparks resulting from use do not create
a hazard e.g. do not hit persons, or ignite flammable
substances;
– Ensure that ventilation openings are kept clear when
working in dusty conditions, if it should become
necessary to clear dust, first disconnect the tool from
the mains supply (use non metallic objects) and avoid
damaging internal parts;
– Always use eye and ear protection. Other personal
protective equipment such as dust mask, gloves, helmet
and apron should be worn;
– Pay attention to the wheel that continues to rotate after
the tool is switched off.
– Do not allow foreign matter to enter the hole for
connecting the rechargeable battery.
– Never disassemble the rechargeable battery and
charger.
– Never short-circuit the rechargeable battery.
Shortcircuiting the battery will cause a great electric
current and overheat. It results in burn or damage to the
battery.
– Do not dispose of the battery in fire. If the battery is burnt,
it may explode.
– Do not insert object into the air ventilation slots of the
charger. Inserting metal objects or inflammables into the
charger air ventilation slots will result in electrical shock
hazard or damaged charger.
– Bring the battery to the shop from which it was purchased
as soon as the post-charging battery life becomes too
short for practical use. Do not dispose of the exhausted
battery.
ADDITIONAL SAFETY WARNINGS
1. 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.
2. Confirm that the push button is disengaged by pushing
push button two or three times before switching the
power tool on.
3. 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.
4. The wheel continues to rotate after the tool is switched
off.
After switching offthe 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.
5. When the machine is not use, the power source should
be disconnected.
6. Be sure to switch OFF and disconnect the attachment
plug from the receptacle to avoid a serious accident
before the depressed center wheel is assembling and
disassembling.
7. Do not use the product if the tool or the battery terminals
(battery mount) are deformed.
Installing the battery could cause a short circuit that
could result in smoke emission or ignition.
8. Keep the tool’s terminals (battery mount) free of swarf
and dust.
○Prior to use, make sure that swarf and dust have not
collected in the area of the terminals.
○During use, try to avoid swarf or dust on the tool from
falling on the battery.
○When suspending operation or after use, do not leave
the tool in an area where it may be exposed to falling
swarf or dust.

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.
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 UC18YFSL charger lights for 1 second,
does not light for 0.5 seconds (offfor 0.5 seconds), or
the charge indicator lamp of UC18YSL3 charger lights
for 0.3 seconds, does not light for 0.3 seconds (offfor 0.3
seconds). In such a case, first let the battery cool, then
start charging.
○When the pilot lamp or charge indicator 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
charger is 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.

About the Mode Change Function
With the storage battery installed to the main unit and the
unit switched on, pressing the Mode Change switch will
switch the operation mode to auto mode. While in Auto
Mode, the Auto Mode display lamp will remain lit.
○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.
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. 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 cordless disc grinder 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 (Fig. 11)
After use, detach the filter and remove any grime or dust
from the screen with an airgun or other tool.
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 cordless disc grinder 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.
CAUTION
In the operation and maintenance of power tools, the
safety regulations and standards prescribed in each
country must be observed.
Important notice on the batteries for the HiKOKI
cordless power tools
Please always use one of our designated genuine
batteries. We cannot guarantee the safety and
performance of our cordless power tool when used with
batteries other than these designated by us, or when
the battery is disassembled and modified (such as
disassembly and replacement of cells or other internal
parts).
NOTE
Due to HiKOKI’s continuing program of research and
development, the specifications herein are subject to
change without prior notice.
