SAFETY INSTRUCTIONS
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.
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.
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 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.
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.
