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, ﬁ re 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

ﬂ ammable 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.

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.

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 inﬂ uence 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.

8

English

b) Use power tools only with speciﬁ cally

designated battery packs.

Use of any other battery packs may create a risk of

injury and ﬁ re.

c) When battery pack is not in use, keep it away

from other metal objects, like paper clips, coins,

keys, nails, screws or other small metal objects,

that can make a connection from one terminal to

another.

Shorting the battery terminals together may cause

burns or a ﬁ re.

d) Under abusive conditions, liquid may be ejected

from the battery; avoid contact. If contact

accidentally occurs, ﬂ ush with water. If liquid

contacts eyes, additionally seek medical help.

Liquid ejected from the battery may cause irritation or

burns.

6) 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.

children and inﬁ rm persons.

SAFETY WARNINGS COMMON FOR

GRINDING OR ABRASIVE CUTTING-

OFF OPERATIONS

a) This power tool is intended to function as a

grinder or cut-oﬀ tool. Read all safety warnings,

instructions, illustrations and speciﬁ cations

provided with this power tool.

Failure to follow all instructions listed below may result in

electric shock, ﬁ re 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 speciﬁ cally

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 ﬂ y 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 ﬂ anges, the arbour hole of the accessory must

ﬁ t the locating diameter of the ﬂ ange.

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 ﬂ ying

debris generated by various operations. The dust mask

or respirator must be capable of ﬁ ltrating 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

ﬂ y 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 ﬂ ammable

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

9

English

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 ﬁ rm 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 speciﬁ c 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-oﬀ wheel.

Abrasive cut-oﬀ wheels are intended for peripheral

grinding, side forces applied to these wheels may cause

them to shatter.

e) Always use undamaged wheel ﬂ anges that are of

correct size and shape for your selected wheel.

Proper wheel ﬂ anges support the wheel thus reducing

the possibility of wheel breakage. Flanges for cut-oﬀ

wheels may be diﬀ erent from grinding wheel ﬂ anges.

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-oﬀ wheel 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 oﬀ the power tool and hold

the power tool motionless until the wheel comes to

a complete stop. Never attempt to remove the cut-

oﬀ wheel 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 ﬁ tted 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. 7);

– Do not use separate reducing bushings or adapters to

adapt large hole abrasive wheels;

10

English

– For tools intended to be ﬁ tted 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 oﬀ wheel for side grinding;

– Ensure that sparks resulting from use do not create

a hazard e.g. do not hit persons, or ignite ﬂ ammable

substances;

– Ensure that ventilation openings are kept clear when

working in dusty conditions, if it should become

necessary to clear dust, ﬁ rst 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 .

WARNING

– When using a cutting-oﬀ wheel, be sure to attach the

cutting-oﬀ guard.

– When using a grinding wheel, be sure to attach the

grinding wheel guard.

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. Conﬁ rm 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 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 eﬀ ective grinding. Too much pressure will result in

reduced rotational speed, inferior surface ﬁ nish, and

overloading which could reduce the life of the machine.

4. The wheel continues to rotate after the tool is switched

oﬀ .

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.

5. When the machine is not use, the power source should

be disconnected.

6. Be sure to switch OFF and pull out the battery to avoid

a serious accident before the depressed center wheel is

assembling and disassembling.

7. Be careful of brake kickback.

This cordless disc 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.

8. 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.

9. 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.

Doing so could cause a short circuit that could result in

smoke emission or ignition.

*1 If the red lamp continues to blink even after the charger

has been attached, check to conﬁ rm that the battery has

been fully inserted.

*2 Although charging will start once the battery has cooled

down even when left in situ, the best practice is to

remove the battery and allow it to cool down in a shaded,

well-ventilated location before charging.

*3

○ Fully insert the battery.

○ Check to conﬁ rm that no foreign matter is stuck to the

battery mount or terminals.

○ Charging will take longer at extremely low ambient

temperatures. Charge the battery in a warm location

(such as indoors).

○ Do not block the air vent. Otherwise the interior will

overheat, reducing the charger’s performance.

○ If the cooling fan is not operating, contact a HiKOKI

Authorized Service Center for repairs.

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 ﬁ rst 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 charge indicator lamp of the charger lights

for 0.3 seconds, does not light for 0.3 seconds (oﬀ for

0.3 seconds). In such a case, ﬁ rst let the battery cool,

then start charging.

○ When the charge indicator lamp ﬂ ickers (at 0.2-second

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.

*2 WARNING

Before use, be sure to tighten the wheel nut with the

included wrench.

NOTE

The wheel washer is speciﬁ cally for this product. Do

not use it for any other product.

*3 About the mode change function

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.

NOTE

○ The mode will only change after a battery is installed and

the switch is pulled once.

○ The current mode will be maintained even if the switch is

on/oﬀ , or the battery is removed/reinserted.

*4 Remaining battery indicator (on tool body)

When using a battery with a remaining battery indicator,

please refer to the indicator lamp on the battery for the

battery remaining power.

MAINTENANCE AND INSPECTION

WARNING

Be sure to turned oﬀ the switch and remove the battery

before 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. Filter cleaning and inspection (Fig. 14)

WARNING

Wear protective glasses and a dust mask when cleaning

the ﬁ lter with an air blow gun.

Failure to do so may result in inhalation or exposure of

the eyes to debris or dust.

After use, remove any debris or dust adhered to the ﬁ lter

using a soft brush. Check the ﬁ lter periodically to ensure

that it is free of scratching, chipping, or tearing. Replace

with a new ﬁ lter if the ﬁ lter is damaged in any way.

NOTE

○ If the mesh is clogged and the debris or dust cannot be

removed, detach the ﬁ lter and clean it with an air gun,

etc.

○ After cleaning, make sure to securely attach the ﬁ lter.

4. 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.

NOTE

In order to expel debris and dust, periodically run the

motor with no load.

5. 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.

6. 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.

7. Storage

Store the power tool and the battery 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,

signiﬁ cantly reducing battery usage time or rendering

the batteries incapable of holding a charge.

However, signiﬁ cantly reduced battery usage time may

be recovered by repeatedly charging and using the

batteries two to ﬁ ve 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 modiﬁ ed (such as

disassembly and replacement of cells or other internal

parts).

NOTE

Due to HiKOKI’s continuing program of research and

development, the speciﬁ cations herein are subject to

change without prior notice.
