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.

c for Grinding and Abrasive
Cutting-O
ff
Operations:
a) Use only wheel types that are recommended for your
power tool and the speci
fi
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-o
ff
wheel.
Abrasive cut-o
ff
wheels are intended for
peripheral grinding, side forces applied to these wheels may
cause them to shatter.
d) 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-o
ff
wheels
may be di
ff
erent from grinding wheel
fl
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
fi
c for Abrasive
Cutting-O
ff
Operations:
a) Do not “jam” the cut-o
ff
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 o
ff
the power tool and hold the
power tool motionless until the wheel comes to a
complete stop. Never attempt to remove the cut-o
ff
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
fi
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 di
ff
erent 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 o
ff
.
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 o
ff
the machine in case of considerable
vibrations or if other malfunctions occur. Check the machine
in order to
fi
nd out the cause.
Always use and store accessories according to the
manufacturer's instructions.
When grinding metal,
fl
ying sparks are produced. Take care
that no persons are endangered. Because of the danger of
