Work Area Safety
1) Keep work area clean and well lit.
Cluttered or dark areas invite
accidents.
2) 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.
3) Keep children and bystanders
away while operating a power tool.
Distractions can cause you to lose
control.
Electrical Safety
1) 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.
2) 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.
3) Do not expose power tools to rain
or wet conditions.
Water entering a power tool will
increase the risk of electric shock.
4) 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.
5) 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.
Personal Safety
1) 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
personal injury.
2) 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.
3) Avoid accidental starting. Ensure
the switch is in the off position
before plugging in.
Carrying power tools with your finger
on the switch or plugging in the
power tools that have the switch on
invites accidents.
4) Remove any adjusting key or
wrench before turning the power

footing and balance at all times.
This enables better control of the
power tool in unexpected situations.
6) Dress properly. Do not wear loose
clothing or jewelry. Keep your hair,
clothing and gloves away from
moving parts.
Loose clothes, jewelry or long hair
can be caught in moving parts.
7) 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.

Power Tool Use and Care
1) 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.
2) 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.
3) Disconnect the plug from the
power source and/or the battery
pack from the power tool before
making any adjustments, changing
accessories, or storing power
tools.
Such preventive safety measures
reduce the risk of starting the power
tool accidentally.
4) 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.
5) Maintain power tools. Check for
misalignment or binding of moving
parts, breakage of parts and any
other condition that may affect the
power tools operation. If damaged,
have the power tool repaired
before use.
Many accidents are caused by poorly
maintained power tools.
6) Keep cutting tools sharp and
clean.
Properly maintained cutting tools with
sharp cutting edges are less likely to
bind and are easier to control.
7) 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
different from those intended could
result in a hazardous situation.
Battery Tool Use and Care
1) Ensure the switch is in the off
position before inserting battery
pack.
Inserting battery pack into power
tools that have the switch on invites
accidents.
2) Recharge only with the charger
specified by the manufacturer.
A charger that is suitable for one type
of battery pack may create a risk of
fire when used with another battery
pack.
3) Use power tools only with
specifically designated battery
packs.
Use of any other battery packs may
create a risk of injury and fire.
4) 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 fire.
5) Under abusive conditions, liquid

occurs, flush with water. If liquid
contacts eyes, additionally seek
medical help.
Liquid ejected from the battery may
cause irritation or burns.
Service
1) Have your power tool serviced by
a qualified repair person using
only identical replacement parts.
This will ensure that the safety of
power tool is maintained.

7) Do not use a damaged accessory.
Before each use inspect the
accessory such as abrasive
wheels for chips and cracks.
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.
8) 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.
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 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.
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 accessory.
Safety instructions for all
operations
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
instructions 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.
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) 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.

12) 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.
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 powdered
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
require 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
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.
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
accessory. 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
woodcarving blade or toothed saw
blade. Such blades create frequent
kickback and loss of control.
Additional safety instructions
for grinding and cutting-off
operations
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 designed
for the selected wheel. Wheels
for which the power tool was not
designed cannot be adequately
guarded and are unsafe.
2) 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.

3) 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 operator
from broken wheel fragments and
accidental contact with wheel and
sparks that could ignite clothing.
4) 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.
5) 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.
6) 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:
1) 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.
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 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.
4) Do not restart the cutting
operation in the workpiece. Let
the wheel reach full speed and
carefully reenter the cut. The
wheel may bind, walk up or kickback
if the power tool is restarted in the
workpiece.
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.

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
direction.
Using a cut-off disc guard
(Available as an accessory,
not included) [Fig.11]
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.
V. OPERATION
NOTE:
Be aware that this tool is always in an
operating condition, since it does not
have to be plugged into an electrical
outlet.
Power switch operation
CAUTION
• Before inserting the battery pack
into the tool, always make sure that
the power switch operates properly
and returns to the “OFF” position
when the rear of the power switch is
depressed.
• Power switch can be locked in “ON”
position. Stay alert when locking
tool in “ON” position and grasp the
tool firmly using support handle and
grip.
To start operation, press and slide the
power switch toward the “ON” position.
[Fig.7]

WARNING
• It should never be necessary to
force the tool. The weight of the tool
applies adequate pressure. Forcing
and excessive pressure could cause
dangerous grinding disc breakage.
• ALWAYS replace grinding disc if tool
is dropped while grinding.
• NEVER bang or hit grinding disc.
• Avoid bouncing and snagging the
grinding disc, especially when
working corners, sharp edges etc.
This can cause loss of control and
kickback.

•Do not jam the Disc or apply excessive
pressure. Do not attempt to make an
excessive depth of cut. Overstressing
the cut-off disc increases the loading
and susceptibility to twisting or
binding of the cut-off disc in the cut
and the possibility 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. Placing
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 using
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
operation. Otherwise, the machine
function 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.

and the motor or battery will stop
operating. The overheat warning lamp
on the control panel illuminates or
flashes when this feature is active.
•If the overheating protection feature
activates, allow the tool to cool
thoroughly (at least 30 minutes).
The tool 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.
• If the tool is operated continuously
under high-load conditions or if it is
used in hot-temperature conditions
(such as during summer), the
overheating protection feature may
activate frequently.
•If the tool is used in cold-temperature
conditions (such as during winter) or
if it is frequently stopped during use,
the overheating protection feature
may not activate.
•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
ambient temperature.

Battery low warning lamp
[Fig.15]
Excessive (complete) discharging of
lithium ion batteries shortens their
service life dramatically. The tool
includes a battery protection feature
designed to prevent excessive
discharging of the battery pack.
• The battery protection feature
activates 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.
•If it is started with too little battery
power remaining, the tool may stop
operating without the battery low
warning lamp flashing first. This
indicates that there is too little battery
power remaining to use the tool, and
the battery pack should be charged
before further use.
•If the tool is subject to a sudden load
during use that causes the motor to
lock up, the overdischarge prevention
sensor may be triggered, and the
battery low warning lamp may flash.
The lamp will stop flashing once you
address the cause of the motor’s
locking up and cycle the trigger.
