WARNING!
The declared vibration total values and the declared noise emission values given in this instruction manual have been measured in
accordance with a standardised test given in EN 62841 and may be used to compare one tool with another. They may be used for a
preliminary assessment of exposure.
The declared vibration and noise emission values represent the main applications of the tool. However, if the tool is used for different
applications, used with different accessories, or poorly maintained, the vibration and noise emission may differ. These conditions may
signicantly increase the exposure levels over the total working period.
An estimation of the level of exposure to vibration and noise should take into account the times when the tool is turned off or when it is
running idle. These conditions may signicantly reduce the exposure level over the total working period.
Identify additional safety measures to protect the operator from the effects of vibration and noise, such as maintaining the tool and the
accessories, keeping the hands warm, and organising work patterns.

ANGLE GRINDER SAFETY WARNINGS
SAFETY WARNINGS COMMON FOR GRINDING, SANDING OR
CUTTING-OFF OPERATIONS:
This power tool is intended to function as a grinder, sander
or cut-off tool. Read all safety warnings, instructions,
illustrations and specications provided with this power tool.
Failure to follow all instructions listed below may result in electric
shock, re and/or serious injury.
Operations such as wire brushing, polishing, or hole cutting
are not to be performed with this power tool. Operations for
which the power tool was not designed may create a hazard and
cause personal injury.
Do not convert this power tool to operate in a way which is not
specically designed and specied by the tool manufacturer. Such
a conversion may result in a loss of control and cause serious
personal injury.
Do not use accessories which are not specically designed
and specied by the tool manufacturer. Just because the
accessory can be attached to your power tool, it does not assure
safe operation.
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 y apart.
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.
The dimensions of the accessory mounting must t the
dimensions of the mounting hardware of the power tool.
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.
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.
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 ying debris generated by various applications. The dust
mask or respirator must be capable of ltrating particles generated
by particular application. Prolonged exposure to high intensity
noise may cause hearing loss.
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
y away and cause injury beyond immediate area of operation.
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.
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.
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.
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.
Do not operate the power tool near ammable materials.
Sparks could ignite these materials.
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:
• Maintain a firm grip with both hands 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.
• Never place your hand near the rotating accessory.
Accessory may kickback over your hand.
• 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.
• 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.
• Do not attach a saw chain woodcarving blade, segmented
diamond wheel with a peripheral gap greater than 10 mm or
toothed saw blade. Such blades create frequent kickback and
loss of control.
SAFETY WARNINGS SPECIFIC FOR GRINDING AND CUTTING-
OFF OPERATIONS
Use only wheel types that are specied for your power tool
and the specic guard designed for the selected wheel. Wheels
for which the power tool was not designed cannot be adequately
guarded and are unsafe.
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.
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.
Wheels must be used only for specied 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.
Always use undamaged wheel anges that are of correct size
and shape for your selected wheel. Proper wheel anges support
the wheel thus reducing the possibility of wheel breakage. Flanges
for cut-off wheels may be different from grinding wheel anges.
13
Do not use worn down wheels from larger power tools. A wheel
intended for larger power tool is not suitable for the higher speed of
a smaller tool and may burst.
When using dual purpose wheels always use the correct guard
for the application being performed. Failure to use the correct
guard may not provide the desired level of guarding, which could
lead to serious injury.
ADDITIONAL SAFETY WARNINGS SPECIFIC FOR CUTTING-
OFF OPERATIONS
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.
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.
When the wheel is binding or when interrupting a cut for any
reason, switch off the power tool and hold it 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.
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.
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.
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.
Do not attempt to do curved cutting. 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,
which can lead to serious injury.
ADDITIONAL SAFETY INSTRUCTIONS FOR SANDING
OPERATIONS
Safety warnings specic for sanding operations:
Use proper sized sanding disc paper. Follow manufacturers
recommendations, when selecting sanding paper. Larger
sanding paper extending too far beyond the sanding pad presents
a laceration hazard and may cause snagging, tearing of the disc
or kickback.
ADDITIONAL SAFETY AND WORKING INSTRUCTIONS
Clamp your workpiece with a clamping device. Unclamped
workpieces can cause severe injury and damage.
The product will restart automatically if stalled. Switch off the
product immediately if it stalls. Determine why the product has
stalled and rectify it, paying heed to the safety instructions. If
necessary, remove the insertion tool.
When grinding metal, hot sparks may be produced that could
cause a risk of re. Keep bystanders and combustible materials
away from the spark ight zone or working area. Do not use dust
extraction when grinding metals.
Prevent ying sparks from hitting your body.
Never reach into the danger area of the product when it is running.
Chips and splinters must not be removed while the product is
running.
Dust created by operating the product can cause respiratory

RISK REDUCTION
It has been reported that vibrations from handheld tools may
contribute to a condition called Raynaud’s Syndrome in certain
individuals. Symptoms may include tingling, numbness, and
blanching of the ngers, usually apparent upon exposure to cold.
Hereditary factors, exposure to cold and dampness, diet, smoking,
and work practices are all thought to contribute to the development
of these symptoms. There are measures that can be taken by the
operator to possibly reduce the effects of vibration:
• Keep your body warm in cold weather. When operating the
product wear gloves to keep the hands and wrists warm. It
is reported that cold weather is a major factor contributing to
Raynaud’s Syndrome.
• After each period of operation, exercise to increase blood
circulation.
• Take frequent work breaks. Limit the amount of exposure per
day.
If you experience any of the symptoms of this condition,
immediately discontinue use and see your doctor about these
symptoms.
