accumulation of powdered metal may cause electrical
hazards.
o) Do not operate the power tool near À 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 ¿ 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 Speci¿ c for Grinding and Abrasive
Cutting-Off Operations:
a) Use only wheel types that are recommended for your
power tool and the speci¿ 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 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 À anges that are of
correct size and shape for your selected wheel. Proper
wheel À anges support the wheel thus reducing the possibility
of wheel breakage. Flanges for cut-off wheels may be
different from grinding wheel À 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 Speci¿ 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 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 Speci¿
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 Speci¿ 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.
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 ¿ nd out the cause.
Always use and store the grinding disks according to the
manufacturer's instructions.
When grinding metal, À 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 À ight zone). Do not use dust extraction.
Due care should be taken that no sparks or sanding dust
À ying 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.

Safety Warnings Specific for Grinding Operations:
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.
Under extreme conditions (e.g. smooth-grinding metals with
the arbour and vulcanized ¿ bre grinding wheel), signi¿ cant
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 ¿ 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.
