GENERAL POWER TOOL
SAFETY WARNINGS
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
mains-operated (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 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.
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 recommendation that the tool
always be supplied via residual current
device with a rated residual current of 30
mA or less.
a) 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 INSTRUCTIONS
FOR ALL OPERATIONS:
Safety Warnings Common for Grinding
Operations:
a) This power tool is intended to
function as a grinder . 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 sanding, wire
brushing, polishing are not recommended
to be performed with this power tool or
cut-off 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) 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.
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.
q) Your hand must hold on the handle when you
are working. Always use the auxiliary handles
supplied with the tool. Loss of control can cause
personal injury
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.
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 OPERATIONS
Safety Warnings Specific for Grinding
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 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.
c) 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.
d) 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.
e) 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.
f) 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.

WORKING HINTS FOR
YOUR ANGLE GRINDER
1. Always start at no load to achieve maximum speed
then start working.
2. Do not force the disc to work faster, reducing the
Disc’s moving speed means longer working time.
3. Always work with a 15-30 angle between disc
and workpiece. Larger angles will cut ridges into the
workpiece and affect the surface nish. Move the
angle grinder across and back and forth over the
workpiece.
4. When using a cutting disc never change the cutting
angle otherwise you will stall the disc and angle
grinder motor or break the disc. When cutting, only cut
in the opposite direction to the disc rotation. If you cut
in the same direction as the disc rotation the disc may
push itself out of the cut slot.
5. When cutting very hard material best results can be
achieved with a diamond disc.
6. When using a diamond disc it will become very hot.
If this happens you will see a full ring of sparks around
the rotating disc. Stop cutting and allow to cool at no
load speed for 2-3 minutes.
7. Always ensure the workpiece is rmly held or
clamped to prevent movement.

MAINTENANCE
Remove the plug from the socket before
carrying out any adjustment, servicing or
maintenance.
There are no user serviceable parts in your power
tool. Never use water or chemical cleaners to clean
your power tool. Wipe clean with a dry cloth. Always
store your power tool in a dry place. Keep the motor
ventilation slots clean. Keep all working controls free
of dust. Occasionally you may see sparks through the
ventilation slots. This is normal and will not damage
your power tool.
If the supply cord is damaged, it must be replaced
by the manufacturer, its service agent or similarly
qualied persons in order to avoid a hazard.
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 ange is tight; check that the wheel is
correctly located on the ange 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.
