WARNING
The vibration emission level given in this information sheet has been measured in accordance with a standardised test given in EN 60745 and
may be used to compare one tool with another. It may be used for a preliminary assessment of exposure.
The declared vibration emission level represents the main applications of the tool. However if the tool is used for different applications, with
different accessories or poorly maintained, the vibration emission may differ. This may significantly increase the exposure level over the total
working period.
An estimation of the level of exposure to vibration should also take into account the times when the tool is switched off or when it is running but
not actually doing the job. This may significantly reduce the exposure level over the total working period.
Identify additional safety measures to protect the operator from the effects of vibration such as: maintain the tool and the accessories, keep the
hands warm, organisation of work patterns.
WARNING! Read all safety warnings and all instructions,
including those given in the accompanying brochure. 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.

Safety Warnings Common for Grinding, Sanding, Wire Brushing
or Abrasive Cutting-Off Operations:
a) This power tool is intended to function as a grinder, sander,
wire brush, 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 as 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) 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.
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
shop 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.
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.
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
-1
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.
2
a) Maintain a firm grip on the power tool and position your body
2
and arm to allow you to resist kickback forces. Always use
2 auxiliary handle, if provided, for maximum control over
2 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.
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:
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.
Safety Warnings Specific for Sanding Operations:
a) Do not use excessively oversized sanding disc paper. Follow
manufacturers 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.
Safety Warnings Specific for Wire Brushing Operations:
a) Be aware that wire bristles are thrown by the brush even
during ordinary operation. Do not overstress the wires by
applying excessive load to the brush. The wire bristles can easily
penetrate light clothing and/or skin.
b) If the use of a guard is recommended for wire brushing, do
not allow any interference of the wire wheel or brush with the
guard. Wire wheel or brush may expand in diameter due to work
load and centrifugal forces.
Appliances used at many different locations including open air
should be connected via a residual current device of 30 mA or less.
Dust and splinters must not be removed while the machine is
running.
Only plug-in when machine is switched off.
Never reach into the danger area of the tool when it is running.
Always use the auxiliary handle.
Immediately switch off the machine in case of considerable vibrations
or if other malfunctions occur. Check the machine in order to find out
the cause.
Always use and store the grinding disks according to the
manufacturer's instructions.
When grinding metal, flying sparks are produced. Take care that no
persons are endangered. Because of the danger of fire, no
combustible materials should be located in the vicinity (spark flight
zone). Do not use dust extraction.
Due care should be taken that no sparks or sanding dust flying from
the workpiece come into contact with you.
When separating stone the guide shoe must be used!
The adjusting nut must be tightened before starting to work with the
machine.
The workpiece must be fixed if it is not heavy enough to be steady.
Never lead the workpiece to the grinding disk with your hand.
Under extreme conditions (e.g. smooth-grinding metals with the
arbour and vulcanized fibre grinding wheel), significant contamination
can build up on the inside of the angle grinder. For safety reasons, in
such conditions the inside should be cleaned thoroughly of metal
deposits and a motor circuit-breaker must be connected in series. If
the motor circuit-breaker trips the machine must be sent for repair.
For accessories intended to be fitted with threaded hole wheel,
ensure that the thread in the wheel is long enough to accept the
spindle length.
For cutting or separating use a closed protection cap, available as an
accessory.

SPECIFIED CONDITIONS OF USE

The angle grinder can be used to cut and rough-grind many different
materials, e.g. metal or stone, for grinding with a plastic grinding
plate and for operation with the wire brush. Always follow the
manufacturer's instructions if you are unsure about anything to do
with the machine..
