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 grounded power tools. Unmodified plugs and matching
outlets will reduce risk of electric shock.
b) Avoid body contact with grounded surfaces, such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric shock if your body is grounded.
c) Do not expose power tools to rain or wet conditions. Wafer 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 influence 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.
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 or jewellery. Keep your hair, clothing
and gloves away from moving parts. Loose clothes, jewellery 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.
3) 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
cannot be controlled with the switch is dangerous and must be repaired.

TROUBLESHOOTING
Although your new angle grinder is really very simple to operate, if you do experience
problems, please check the following:

1. If your grinder will not operate check the power at the main plug.
2. If your grinder wheel wobbles or vibrates, check that outer flange is tight, check
that the wheel is correctly located on the flange plate.
3. If there is any evidence that the wheel is damaged do not use as the damaged
wheel may disintegrate, remove it and replace with a new wheel. Dispose of old
wheels sensibly.
4. If working on aluminum or a similar soft alloy, the wheel will soon become clogged
and will not grind effectively.
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.

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
d) 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.
e) 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.
f) 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.
g) 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.
h) 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.
i) 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.
j) 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.
k) 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

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.
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.
5. TO USE THE GRINDER
Attention: Do not switch the grinder on whilst the disc is in contact with the workpiece.
Allow the disc to reach full speed before starting to grind.Hold your angle grinder with
one hand on the main handle and other hand firmly around the auxiliary
handle.Always position the guard so that as much of the exposed disc as possible is
pointing away from you.Be prepared for a stream of sparks when the disc touches the
metal.For best tool control, material removal and minimum overloading, maintain an
angle between the disc and work surface of approximately 15°-30° when grinding.Use
caution when working into corners as contact with the intersecting surface may cause

the grinder to jump or twist.When grinding is complete allow the workpiece to cool. Do
not touch the hot surface.
6. WHEEL GUARD FOR CUTTING AND CUTTING DISC ARE NOT SUPPLIED.
Warning! For cutting metal, always work with the wheel guard for cutting.
When cutting, do not press, tilt or oscillate the machine. Work with moderate feed,
adapted to the material being cut.
Do not reduce the speed of running down cutting discs by applying sideward pressure.
The direction in which the cutting is performed is important.
The machine must always work in an up-grinding motion. Therefore, never move the
machine in the other direction! Otherwise, the danger exists of it being pushed
uncontrolled out of the cut.
7. OVERLOAD
Overloading will cause damage to the motor of your angle grinder. This can happen if
your angle grinder is subjected to heavy use for prolonged periods of time.
Do not in any circumstances, attempt to exert too much pressure on your angle
grinder to speed up your work.
If your angle grinder becomes too hot, run you angle grinder under no load for 2-3
minutes until it has cooled to normal operation temperature.
WORKING HINTS FOR YOUR ANGLE GRINDER
1. Your angle grinder is useful for both cutting through metals, i.e. for removing screw
heads, and also for cleaning /preparing surfaces, i.e. before and after welding
operations.
2. Different types of wheel/cutter will allow the grinder to meet various needs.
Typically, grinding wheels and cutting discs are available for mild steel, stainless steel,
stone and brick. Diamond impregnated discs are available for very hard materials.
3. If the grinder is used on soft metals such as aluminum the wheel will soon clog and
will have to be changed.
4. At all times, let the grinder do the work, do not force it or apply excessive
pressure to the wheel/disc.
5. If cutting a slot ensure that the cutter is kept aligned with the slot, twisting the
cutter may cause the disc to shatter. If cutting through thin sheet, only allow the cutter
to just project through the material, excessive penetration can increase the chance of
causing damage.
6. If cutting stone or brick, it is advisable to use a dust extractor.

4. SLIDE THE ON/OFF SWITCH
To start the power tool, first press the back of on/off switch, then push the on/off
switch (D) forward.
To lock the on/off switch (D), press the on/off switch (D) down at the front until it
engages.
To switch off the power tool, release the on/off switch (D) or, if it is locked, briefly
press down the back of the on/off switch (D) and then release it
5.TO USE THE GRINDER
Attention: Do not switch the grinder on whilst the disc is in contact with the
workpiece. Allow the disc to reach full speed before starting to grind.
Hold your angle grinder with one hand on the main handle and other hand firmly
around the auxiliary handle.
Always position the guard so that as much of the exposed disc as possible is pointing
away from you
Be prepared for a stream of sparks when the disc touches the metal

For best tool control, material removal and minimum overloading, maintain an angle
between the disc and work surface of approximately 15°-30° when grinding.
Use caution when working into corners as contact with the intersecting surface may
cause the grinder to jump or twist.
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 OPERATION
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 operator from broken wheel fragments and accidental contact
with wheel.
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.
Additional Safety Warnings Specific for Abrasive Cutting-Off Operations
ADDITIONAL SAFETY INSTRUCTIONS FOR 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 whee 丨 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.
ADDITIONAL SAFETY INSTRUCTIONS FOR SANDING
OPERATIONS
Safety Warnings Specific for Sanding Operations
a) Do not use excessively oversized sanding disc paper. Follow manufacturer’s
recommendations, when selecting sanding paper. Larger sanding paper
extending beyond the sanding pad presents a laceration hazard and may cause
snagging, tearing of the disc or kickback
