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. BATTERY TOOL USE AND CARE
a) 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.

7
ENLithium-Ion cordless angle grinder
b) Use power tools only with specifically designated
battery packs. Use of any other battery packs may
create a risk of injury and fire.
c) 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.
d) Under abusive conditions, liquid may be ejected
from the battery; avoid contact. If contact
accidentally occurs, flush with water. If liquid
contacts eyes, additionally seek medical help.
Liquid ejected from the battery may cause irritation or
burns.
6. SERVICE
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 OR
ABRASIVE CUTTINGOFF OPERATIONS
a) 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.
b) 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.
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. 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 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.
k) 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.
l) 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.
m) 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.
n) Do not operate the power tool near flammable
materials.
Sparks could ignite these materials.
o) Do not use accessories that require liquid
coolants.
Using water or other liquid coolants may result
in electrocution or shock.
p) 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

8
ENLithium-Ion cordless angle grinder
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 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 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 the operator
from broken wheel fragments, 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.
ADDITIONAL SAFETY
WARNINGS SPECIFIC FOR
ABRASIVE 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 wheel 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.
SAFETY WARNINGS FOR
BATTERY PACK
a) Do not dismantle, open or shred cells or battery
pack.
b) Do not short-circuit a battery pack. Do not store
battery packs haphazardly in a box or drawer
where they may short-circuit each other or be
short-circuited by conductive materials. When
battery pack is not in use, keep it away from other

9
ENLithium-Ion cordless angle grinder
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.
c) Do not expose battery pack to heat or fire. Avoid
storage in direct sunlight.
d) Do not subject battery pack to mechanical
shock.
e) In the event of battery leaking, do not allow the
liquid to come into contact with the skin or eyes.
If contact has been made, wash the affected
area with copious amounts of water and seek
medical advice.
f) Keep battery pack clean and dry.
g) Wipe the battery pack terminals with a clean dry
cloth if they become dirty.
h) Battery pack needs to be charged before use.
Always refer to this instruction and use the

Rough Grinding
WARNING! Never use a
cutting disc for roughing.
Cutting See Fig. G
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 finish. 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

1212
ENLithium-Ion cordless angle grinder
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 firmly held or clamped
to prevent movement.
MAINTENANCE
Remove the battery 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.
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 wheel wobbles or vibrates, check that
outer flange is tight; check that the wheel is correctly
located on the flange plate.
2. 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.
3. If working on aluminum or a similar soft alloy, the
wheel will soon become clogged and will not grind
effectively.
ENVIRONMENTAL
PROTECTION
Waste electrical products should not be disposed
of with household waste. Please recycle where
facilities exist. Check with your Local
