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 signifi cantly 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 signifi cantly 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 .
Failure to follow the warnings and instructions may result in
electric shock, fi re and/or serious injury.

ANGLE GRINDER SAFETY WARNINGS
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 specifi cations provided with
this power tool. Failure to follow all instructions listed below may
result in electric shock, fi re 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 specifi cally 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 fl y 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 fl anges, the
arbour hole of the accessory must fi t the locating diameter of
the fl ange. 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 shop apron capable of stopping small abrasive or
workpiece fragments. The eye protection must be capable of
stopping fl ying debris generated by various operations. The dust
mask or respirator must be capable of fi ltrating 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 fl y 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. 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 fl ammable 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 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 fi rm 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.
Safety Warnings Specifi c for Grinding and Abrasive
Cutting-Off Operations:
a) Use only wheel types that are recommended for your
power tool and the specifi c 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 the 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 fl anges that are of correct
size and shape for your selected wheel. Proper wheel fl anges
support the wheel thus reducing the possibility of wheel breakage.
Flanges for cut-off wheels may be different from grinding wheel
fl anges.
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 Specifi c 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 Specifi c 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 Specifi c 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.
