II. ADDITIONAL
SAFETY RULES
Safety instructions for all op-
erations
Safety warning common for Grinding
or Abrasive Cutting-off operations:
1) This power tool is intended to
function as a grinder, or cut-off
tool. Read all safety warnings,
instructions, illustrations and
specifications provided with this
power tool. Failure to follow all in-
structions listed below may result in
electric shock, fire and/or serious
injury.
2) Operations such as sanding,
wire brushing, 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.
3) 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.
4) 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.

- 7 -
5) 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.
6) The arbour size of wheels, flanges,
backing pads or any other ac-
cessory must properly fit the
spindle of the power tool. Acces-
sories with arbour holes that do not
match the mounting hardware of
the power tool will run out of bal-
ance, vibrate excessively and may
cause loss of control.
7) Do not use a damaged accessory.
Before each use inspect the ac-
cessory such as abrasive wheels
for chips and cracks. If power tool
or accessory is dropped, inspect
for damage or install an undam-
aged accessory. After inspecting
and installing an accessory, po-
sition yourself and bystanders
away from the plane of the rotat-
ing accessory and run the power
tool at maximum no-load speed
for one minute. Damaged acces-
sories will normally break apart dur-
ing this test time.
8) Wear personal protective
equipment. Depending on ap-
plication, 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 eye
protection must be capable of
stopping flying debris generated by
various operations. The dust mask
or respirator must be capable of fil-
trating particles generated by your
operation. Prolonged exposure to
high intensity noise may cause
hearing loss.
9) 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.
10) Hold power tool by insulated grip-
ping surfaces only, when perform-
ing an operation where the cutting
accessory may contact hidden wir-
ing or its own cord. Cutting acces-
sory contacting a “live” wire may
make exposed metal parts of the
power tool “live” and shock the op-
erator.
11) 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 acces-
sory.
12) Never lay the power tool down
until the accessory has come to a
complete stop. The spinning ac-
cessory may grab the surface and
pull the power tool out of your con-
trol.
13) 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.
14) Regularly clean the power tool’s
air vents. The motor’s fan will draw
the dust inside the housing and
excessive accumulation of pow-
dered metal may cause electrical
hazards.
15) Do not operate the power tool near
flammable materials. Sparks could
ignite these materials.
16) Do not use accessories that re-
quire liquid coolants. Using water
or other liquid coolants may result in
electrocution or shock.

Further safety instructions for
all operations
Kickback and Related Warnings
Kickback is a sudden reaction to a
pinched or snagged rotating wheel,
backing pad, brush or any other acces-
sory. 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 direc-
tion 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.
1) 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.
2) Never place your hand near the
rotating accessory. Accessory may
kickback over your hand.
3) 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.
4) Use special care when working
corners, sharp edges etc. Avoid
bouncing and snagging the ac-
cessory. Corners, sharp edges or
bouncing have a tendency to snag
the rotating accessory and cause
loss of control or kickback.
5) Do not attach a saw chain wood-
carving blade or toothed saw
blade. Such blades create frequent
kickback and loss of control.
Additional safety instructions for
grinding and cutting-off opera-
tions
Safety warnings specific for Grinding
and Abrasive Cutting-off operations:
1) Use only wheel types that are
recommended for your power
tool and the specific guard de-
signed for the selected wheel.
Wheels for which the power tool
was not designed cannot be ade-
quately guarded and are unsafe.
2) The guard must be securely at-
tached to the power tool and po-
sitioned for maximum safety, so
the least amount of wheel is ex-
posed towards the operator. The
guard helps to protect operator
from broken wheel fragments and
accidental contact with wheel.
3) Wheels must be used only for rec-
ommended applications. For exam-
ple: 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.
4) 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 grind-
ing wheel flanges.
5) 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.

- 9 -
Additional Safety Warnings Spe-
cific for Abrasive Cutting-Off Op-
erations:
1) Do not “jam” the cut-off wheel or
apply excessive pressure. Do
not attempt to make an exces-
sive 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.
2) 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.
3) 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 com-
plete stop. Never attempt to re-
move the cut-off wheel from the
cut while the wheel is in motion
otherwise kickback may occur.
Investigate and take corrective ac-
tion to eliminate the cause of wheel
binding.
4) Do not restart the cutting opera-
tion in the workpiece. Let the
wheel reach full speed and care-
fully reenter the cut. The wheel
may bind, walk up or kickback if the
power tool is restarted in the work-
piece.
5) 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.
6) 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.

Grinding operation
ALWAYS hold the tool firmly with one
hand on grip and the other on the side
handle. Turn on the tool on and then
apply the wheel or disc to the work-
piece.
In general, keep the edge of the
wheel or grinding disc at an angle of
about 15 degrees to the workpiece
surface.
When using a new grinding disc, do
not work the grinder in the B direction
or it will cut into the workpiece. Once
the edge of the grinding disc has been
rounded off by use, the grinding disc
may be worked in both A and B direc-
tion.
Using a cut-off disc guard
(EY9X213E) (Available as an
accessory, not included)
WARNING:
• When using an abrasive cut-off
disc, be sure to use only the cut-off
disc guard designed for this use
with cut-off disc.
• NEVER use cut-off disc for grinding.
• Do not jam the Disc or apply ex-
cessive pressure. Do not attempt
to make an excessive depth of cut.
Overstressing the cut-off disc in-
creases the loading and suscepti-
bility to twisting or binding of the
cut-off disc in the cut and the pos-
sibility of kickback, cut-off disc
breakage and overheating of the
motor may occur.
• Do not start when disc is in the
workpiece. To do so causes the
cut-off disc binding or kickback. Let
the cut-off disc reach full speed and
then carefully cut the workpiece.
• During cutting operations, never
change the angle of the disc. Plac-
ing side pressure on the cut-off
disc (as in grinding) will cause the
disc to crack and break, causing
serious personal injury.
CAUTION:
• To prevent excessive temperature
increase of the tool surface, do not
operate the tool continuously us-
ing two or more battery packs. The
tool needs cool-off time before
switching to another pack.
• Do not close up ventilation slots on
the sides of the body during opera-
tion. Otherwise, the machine func-
tion is adversely affected to cause a
failure.
• Do NOT strain the tool (motor). This
may cause damage to the unit.
• Use the tool in such a way as to
prevent the air from the ventilation
slots from blowing directly onto
your skin. Otherwise, you may get
burned.
Make sure the side.

Indicator lamp for On lock
warning lamp function
The grinder will not start when the
switch is at the ON position (switch
lever at ON), even when the battery
pack is inserted. The warning lamp
will flash at this time to indicate that
the on lock start prevention function
has operated.
Press the switch to the OFF position
(switch lever at OFF) and then press
it back to the ON position (switch
lever at ON) to start the grinder.
Overheat warning lamp
The overheating protection feature
halts operation to protect the battery
pack in the event of overheating. The
overheat warning lamp on the control
panel flashes when this feature is ac-
tive.
• If the overheating protection feature
activates, allow the tool to cool thor-
oughly (at least 30 minutes). The
battery is ready for use when the
overheat warning lamp goes out.
• Avoid using the tool in a way that
causes the overheating protection
feature to activate repeatedly.
Battery low warning lamp
Excessive (complete) discharging of
lithium ion batteries shortens their ser-
vice life dramatically. The tool includes
a battery protection feature designed to
prevent excessive discharging of the
battery pack.
• The battery protection feature acti-
vates immediately before the battery
loses its charge, causing the battery
low warning lamp to flash.
• If you notice the battery low warning
lamp flashing, charge the battery
pack immediately.

For Appropriate Use of
Battery pack
Li-ion Battery pack (EY9L40/EY9L41)
• For optimum battery life, store the
Li-ion battery pack following use
without charging it.
• When charging the battery pack,
confirm that the terminals on the
battery charger are free of foreign
substances such as dust and water etc.
Clean the terminals before charging
the battery pack if any foreign
substances are found on the terminals.
The life of the battery pack terminals
may be affected by foreign
substances such as dust and water
etc. during operation.
• 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 sparks, burns or
a fire.
• When operating the battery pack,
make sure the work place is well
ventilated.
• When the battery pack is removed
from the main body of the tool, re-
place the battery pack cover imme-
diately in order to prevent dust or dirt
from contaminating the battery ter-
minals and causing a short circuit.
Battery Pack Life
The rechargeable batteries have a
limited life. If the operation time
becomes extremely short after
recharging, replace the battery pack
with a new one.

Charging
Cautions for the Li-ion Battery
Pack
• If the temperature of the battery pack
falls approximately below −10°C
(14°F), charging will automatically
stop to prevent degradation of the
battery.
Common Cautions for the
Li-ion/Ni-MH/Ni-Cd Battery Pack
• The ambient temperature range is
between 0°C (32°F) and 40°C (104°F).
If the battery pack is used when the
battery temperature is below 0°C (32°F),
the tool may fail to function properly.
• When charging a cool battery pack
(below 0°C (32°F)) in a warm place,
leave the battery pack at the place and
wait for more than one hour to warm
up the battery to the level of the am-

- 15 -
bient temperature.
• Cool down the charger when charging
more than two battery packs consecu-
tively.
• During charging, the charger may
become slightly warm. This is normal.
Do NOT charge the battery for a long
period.
CAUTION:
To prevent the risk of fire or damage
to the battery charger.
• Do not use power source from an
engine generator.
• Do not cover vent holes on the
charger and the battery pack.
• Unplug the charger when not in use.

cally.
4. The charge lamp (green) will flash
slowly once the battery is approxi-
mately 80% charged.
5. When charging is completed, the
charging lamp will start flashing
quickly in green color.
6. If the temperature of the battery pack
is 0°C or less, charging takes longer
to fully charge the battery pack than
