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
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.

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 or polishing is 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 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 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.
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.

Safety Instructions For All Operations
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
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
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 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.
Additional Safety Instructions For Cutting-Off Operations
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 reenter 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.

Operating Instructions
Your switch is locked off to prevent accidental starting. With your hand on the on/off
switch (a) use your finger to push lever (b) forward and then depress on/off switch (a).
Then release lever (b). Your tool is now on. To switch off just release on/off switch.
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 150 -300 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.
WARNING! For cutting metal, always work with the wheel guard for cutting.
When cutting, do not press, tilt or oscillate the tool. 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 tool must always work in an up-grinding motion. Therefore, never move the tool in
the other direction! Otherwise, the danger exists of it being pushed uncontrolled out of
the cut.
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.
Customer Helpline 0333 3201989
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 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.
Remove the plug from the socket before carrying out any adjustment, servicing or
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 qualified persons in order to avoid a hazard.
Customer Helpline 0333 3201989
Trouble Shooting
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
4. If working on aluminum or a similar soft alloy, the wheel will soon become clogged
and will not grind effectively.
