SAFETY INSTRUCTIONS
General safety instructions for grinding, working with wire
brushes and abrasive cutting.
a) This power tool is intended to function as a grinder, wire
brush, or cut-off tool. Read all safety warnings, instruc-
tions, illustrations and speci cations provided with this
power tool. Failure to follow all instructions listed below may
result in electric shock, re and/or serious injury.
b) Operations such as sanding or polishing are not recom-
mended 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 speci 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. Acces-
sories running faster than their rated speed can break and 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) The arbour size of wheels, anges, backing pads or any
other accessory must properly t 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

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 signicantly 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 signicantly reduce the exposure level over the total working period. Identify ad-
ditional 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 instruc-
tions, including those given in the accompanying
brochure. Failure to follow the warnings and instructions may
result in electric shock, re and/or serious injury.
Save all warnings and instructions for future reference.
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 acces-
sories 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 protec-
tors, gloves and shop apron capable of stopping small
abrasive or workpiece fragments. The eye protection must
be capable of stopping ying debris generated by various
operations. The dust mask or respirator must be capable of
ltrating particles generated by your operation. Prolonged expo-
sure 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 pro-
tective equipment. Fragments of workpiece or of a broken
accessory may y away and cause injury beyond immediate
area of operation.
j) Hold power tool by insulated gripping surfaces 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 shock
the operator.
k) 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.
l) 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.
m) Regularly clean the power tool’s air vents. The motor’s
fan will draw the dust inside the housing and excessive accu-
mulation of powdered metal may cause electrical hazards.
n) Do not operate the power tool near ammable materi-
als. Sparks could ignite these materials.
o) 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 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 Specic for Grinding and Abrasive
Cutting-Off Operations:
a) Use only wheel types that are recommended for your
power tool and the specic guard designed for the selected
wheel. Wheels for which the power tool was not designed can-
not 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 applica-
tions. 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 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.
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 Specic 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 Specic 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.
Dust and splinters must not be removed while the machine
is running.
Never reach into the danger area of the tool when it is running.
Always use the auxiliary handle.
Always use the protecting cap when roughing-down and
separating.
Immediately switch off the machine in case of considerable
vibrations or if other malfunctions occur. Check the machine in
order to nd out the cause.
Always use and store the grinding disks according to the
manufacturer’s instructions.
When grinding metal, ying sparks are produced. Take care
that no persons are endangered. Because of the danger of
re, no combustible materials should be located in the vicinity
(spark ight zone). Do not use dust extraction.
Due care should be taken that no sparks or sanding dust ying
from the workpiece come into contact with you.
The adjusting nut must be tightened before starting to work with
the machine.
The workpiece must be xed if it is not heavy enough to be
steady. Never lead the workpiece to the grinding disk with your
hand.
For accessories intended to be tted 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.
Do not dispose of used battery packs in the household refuse
or by burning them.
Do not store the battery pack together with metal objects (short
circuit risk).
Use only CCR18 battery chargers for charging CBATR18
battery packs. Do not use battery packs from other systems.
Never break open battery packs and chargers and store only in
dry rooms. Keep dry at all times.
