IMPORTANT SAFETY INSTRUCTIONS
SAFETY WARNINGS COMMON FOR GRINDING
OPERATIONS
This power tool is intended to function as a grinder
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.
Operations for which the power tool was not
designed may create a hazard and cause personal
injury.
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.
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.
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.
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 cause loss of control.
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.
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.
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.
Hold 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 shock the operator.
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.
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.
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.
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.
Do not operate the power tool near flammable
materials. Sparks could ignite these materials.
Do not use accessories that require liquid coolants.
Using water or other liquid coolants may result in
electrocution or shock.
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.

4
IMPORTANT SAFETY INSTRUCTIONS
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.
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.
Always use undamaged wheel flanges 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 different from grinding
wheel flanges.
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.
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.
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 startup. 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.
f. 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.
ANGLE GRINDER SAFETY PRECAUTIONS
Check that the speed marked on the grinding
wheel is equal to or greater than the rated speed of
the tool.
Ensure that the dimensions of the grinding wheel
are compatible with the tool and that the wheel fits
the spindle.
Grinding wheels must be stored in a dry place.
Do not store objects on top of the grinding wheels.
Grinding wheels must not be used for any
operation other than grinding.
Inspect the grinding wheel before use to ensure
that it is not chipped or cracked. Chips or cracks
can cause the wheels to shatter, resulting in
possible serious injury.
Ensure that the grinding wheel is correctly mounted
and tightened before use and run the tool at no
load speed for 30 seconds in a safe position.

5
IMPORTANT SAFETY INSTRUCTIONS
Stop immediately if there is considerable vibration
or if other defects are detected. If this condition
occurs, check the tool to determine the cause.
Do not use separate reducing bushings or adapters
to adapt large hole grinding wheels.
Check that the workpiece is properly supported.
Ensure that sparks resulting from use do not create
a hazard e.g. do not hit people, or ignite flammable
substances.
Always use protective safety glasses and ear
protectors.
Use other personal protective equipment such as
gloves, apron and helmet when necessary.
Never place the tool on the floor or other surfaces
while it is running. Grinding wheels continue to
rotate after the tool is switched off. Never touch the
wheel or place it on the fl oor or other surfaces
while it is rotating.
The flange and clamp nut must have same outer
diameter.
Use the tool only for approved applications. Never
use coolants or water or use the tool as a fixed
tool.
Grip the tool securely with both hands while
operating.

WARNING. Always wear safety glasses
and keep guard in place when grinding.
Hot metal sparks from metal grinding can cause a
fire. Avoid spark contact with flammable materials
such as saw dust or clothing.
Grinding wheels must be free of fissures and
cracks. Fissures and cracks can cause a grinding
wheel to shatter resulting in possible serious injury.
Thoroughly inspect a new grinding wheel before it
is installed on the grinder.
1. Use a wooden hammer for the inspection.
2. Using the hammer, lightly tap all around the
wheel, carefully listening to the resulting
sounds.
3. Any places with fissures or cracks will result in
a different sound. Do not use a wheel
containing fissures or cracks. When installing a
new grinding wheel, a no load revolution test of
approximately one minute must be carried out
with the grinding wheel facing a safe direction,
i.e. away from people or objects.
DANGER. Never attach a wood cutting
or carving blade of any type to this angle
grinder. It is only designed for grinding
metal. Use for any other purpose is not
recommended and creates a hazard
which will result in serious injury.
WARNING. Do not allow familiarity with
products to make you careless.
Remember that a careless fraction of a
second is sufficient to inflict injury.
WARNING. Always wear eye protection
with side shields marked to comply with
ANSI Z87.1. Failure to do so could result
in objects being thrown into your eyes,
resulting in possible serious injury.
CONNECTING TO A POWER SUPPLY
Make sure the on/off switch is in its off position.
Connect the plug with a suitable socket.
WARNING. Check the voltage!
The voltage must comply with the
information on the rating label.
CAUTION. Never cover air vents. They

OPERATION
Secure all work before beginning a grinding
operation.
Secure small workpieces in a vise or clamp to a
workbench.
DANGER. Never use your grinder with
the guard removed. It has been
designed for use only with the guard
installed. Attempting to use grinder with
guard removed will result in loose
particles being thrown against the
operator resulting in serious personal
injury.
WARNING. Never use your grinder
without wearing eye protection.
Following this rule will reduce the risk of
serious personal injury.
The key to efficient operation begins by controlling
the pressure and surface contact between the
grinding wheel and workpiece. Flat surfaces are
ground at an acute angle, normally between 5 to 15
degrees.
For maximum control, hold the grinder in front and
away from you with both hands, keeping the
grinding wheel clear of the workpiece. Start your
grinder and let the motor and grinding wheel build
up to full speed. Gradually lower grinder until the
grinding wheel contacts the workpiece.
For best results keep the grinder tilted at an angle
from 5 to 15 degrees, Fig.8, and continuously
moving at a steady, consistent pace. Move the
grinder back and forth or up and down over the
work area. Keep the grinder moving so that an
excessive amount of material is not removed from
one area. If the grinder is held in one spot too long,
it will gouge and cut grooves in the workpiece. If
the grinder is held at too sharp an angle, it will also
gouge the workpiece because of concentration of
pressure on a small area.
Use just enough pressure to keep the grinder from
chattering or bouncing. Heavy pressure will
decrease its speed and put a strain on the motor.
Normally the weight of the tool alone is adequate
for most grinding jobs. Use light pressure when
grinding jagged edges or loose bolts where there is
the potential for the grinder to snag on the metal
edge.
