GENERAL SAFETY INSTRUCTIONS
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 mainsoperated (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 an earth
leakage circuit breaker. Use of an earth
leakage circuit breaker reduces the risk of
electric shock.
3) PERSONAL SAFETY
a. 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. 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.
c. Prevent unintentional starting. Ensure the
switch is in the off-position before
connecting to power source and/or battery
pack, picking up or carrying the tool.
Carrying power tools with your finger on the
switch or energising power tools that have the
switch on invites accidents.
d. Remove any adjusting key or wrench
before turning the power tool on. A wrench
or a key left attached to a rotating part of the
power tool may result in personal injury.
e. Do not overreach. Keep proper footing and
balance at all times. This enables better
control of the power tool in unexpected
situations.
f. Dress properly. Do not wear loose clothing

4
or jewelry. Keep your hair, clothing and gloves
away from moving parts. Loose clothes,
jewelry or long hair can be caught in moving
parts.
g. If devices are provided for the connection
of dust extraction and collection facilities,
ensure these are connected and properly
used. Use of dust collection can reduce dust-
related hazards.
4) POWER TOOL USE AND CARE
a. 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.
b. 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.
c. 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.
d. 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.
e. Maintain power tools. Check for
misalignment or binding of moving parts,
breakage of parts and any other condition
that may affect the power tool’s operation.
If damaged, have the power tool repaired
before use. Many accidents are caused by
poorly maintained power tools.
f. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting
edges are less likely to bind and are easier to
control.
g. Use the power tool, accessories and tool
bits etc., in accordance with these
instructions, 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.
5) SERVICE
Have your power tool serviced by a qualified
repair person using only identical replacement
parts. This will ensure that the safety of the power
tool is maintained.

SAFETY WARNINGS COMMON FOR
GRINDING, SANDING, WIRE BRUSHING,
POLISHING OR ABRASIVE
Cutting-Off Operations:
a. This power tool is intended to function as a
grinder, sander, wire brush, polisher 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.
b. Operations such as grinding, sanding, wire
brushing, polishing or cutting-off 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, flanges, backing
pads or any other accessory must properly
fit the spindle of the power tool. Accessories
with arbour holes that do not match the
mounting hardware of the power tool will run
out of balance, vibrate excessively and may

6
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 accessory
may contact hidden wiring or its own cord.
Cutting accessory contacting a "live" wire
may 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.
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.

7
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.
ADDITIONAL SAFETY INSTRUCTIONS
FOR GRINDING AND CUTTING-OFF
OPERATIONS
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 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.
c. 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.
d. 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.
e. 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.
WARNINGS: The blade guard must always be
locked by the lock screw in its detent in the
central position. Never change the angle of the
guard to any other position.
The end cover on the blade guard must never be
removed. Never attempt to operate the machine
without all of its blade guards in place.

Electrical connection
The network voltage must conform to the voltage
indicated on the tool name plate. Under no
circumstances should the tool be used when the
power supply cable is damaged.
A damaged cable must be replaced immediately
by an authorized Customer Service Center. Do not
try to repair the damaged cable yourself. The use of
damaged power cables can lead to an electric
shock.
Extension cable
If an extension cable is required, it must have a
sufficient cross-section so as to prevent an
excessive drop in voltage or overheating. An
excessive drop in voltage reduces the output and
can lead to failure of the motor. The following table
shows you the correct cable diameter as a function
of the cable length for this machine. Use only
approved extension cables. Never use two
extension cables together. Instead, use one long
one.
UNPACKING
Carefully remove the tool and all loose items from
the shipping container.
Retain all packing materials until after you have
inspected and satisfactorily operated the machine.

ADJUSTING THE ROTATION SPEED
The speed of the machine is variable to suit
different tasks. It can be adjusted from 1600/min
up to 4800/min by using the thumb wheel. turn in
the rightward direction to increase the speed and
in the leftward direction to decrease the speed.
HOW TO USE THE TOOL
Effective control of this machine requires two-
handed operation for maximum safety and
control.
The proper hold is to keep one hand on the main
handle and the other hand on the grip . It is vitally
important to keep stable footing at all times.
GRINDING OPERATIONS
Once the machine is set up and all safety
measures and equipment are in place, begin by
turning on the machine.
Begin grinding. It is not necessary to use excessive
down force. Allow the machine to work at the pace
it was intended.
WARNING:Whenever grinding small workpieces
always take measures to clamp the workpieces
down. Otherwise they will be flung with great
force by the grinding wheel, causing a hazard.
MAINTENANCE
Every 50 hours of operation blow compressed
air through the motor while running at no load
to clean out accumulated dust. (If operating in
especially dusty conditions, perform this operation
more often.)

10
KEEP TOOL CLEAN
Periodically blow out all air passages with dry
compressed air. All plastic parts should be cleaned
with a soft damp cloth. NEVER use solvents to
clean plastic parts. They could possibly dissolve or
otherwise damage the material.
Wear safety glasses while using compressed air.
THE CARBON BRUSHES
The carbon brushes are a normal wearing part and
must be replaced when they reach their wear limit.
NOTE: Checking and replacing the carbon
brushes should be entrusted to a qualified
service center.
The carbon brushes furnished will last
approximately 50 hours of running time or 10,000
on/off cycles. Replace both carbon brushes when
either has less than 1/4" length of carbon
remaining. To inspect or replace brushes, first
unplug the machine and lay it on its side. To
inspect or replace brushes, first unplug the
machine. Carefully
remove the 4 screws to separate the rear handle
halves and then remove the 4 screws which
connect the handle to the motor housing. Lift
away the left-hand handle half first. There will still
be wires connected to the rear handle, so take care
that these are not stressed. Simply hold the rear
handle off to one side. Next remove the two screws
holding on the Electronics Unit to allow access to
the Brush screws. Hold the Electronics Unit off to
one side and avoid stressing the wires. Rotate the
spiral spring to relieve the tension on the brush
and slide it out of the holder.
Unscrew the two screws which hold the brush
leads and remove the Carbon Brushes.
NOTE: When putting the Carbon Brushes back
into the Carbon Brush Holders it is essential
that both flanges go back inside the holder.
NOTE: To reinstall the same brushes, first make
sure the brushes go back in the way they came
out. Otherwise a break-in period will occur that
will reduce motor performance and increase
brush wear.
Replacing is the reverse of removal. When
Replacing all covers, take great care that all wires
are in place and not in a position to be pinched
when they are retightened. It is recommended
that, at least once a year, you take the tool to an
Authorized Service Center for a thorough cleaning
and lubrication.
If the replacement of the power supply
cord is necessary, this has to be done by the
manufacturer or their agent in order to avoid a
safety hazard.
WARNING: All repairs must be entrusted to an
authorized service center. Incorrectly performed
repairs could lead to injury or death.
