Hold the power tool by insulated gripping sur-
u
faces only, when performing an operation
where the cutting accessory may contact hid-
den wiring. Cutting accessory contacting a
"live" wire may 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 ac-
u
cessory 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
u
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.
u
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 flam-
u
mable materials. Sparks could ignite these ma-
terials.
Do not use accessories that require liquid
u
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 on the power tool and po-
u
sition your body and arm to allow you to res-
ist 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 ac-
u
cessory. Accessory may kickback over your
hand.
Do not position your body in the area where
u
power tool will move if kickback occurs.
18 | English
Kickback will propel the tool in direction oppos-
ite to the wheel's movement at the point of
snagging.
Use special care when working corners,
u
sharp edges etc. Avoid bouncing and snag-
ging the accessory. Corners, sharp edges or
bouncing have a tendency to snag the rotating
accessory and cause loss of control or kick-
back.
Do not attach a saw chain woodcarving blade
u
or toothed saw blade. Such blades create fre-
quent kickback and loss of control.
Safety Warnings specific for Grinding and
Abrasive Cutting-Off operations
Use only wheel types that are recommended
u
for your power tool and the specific guard de-
signed 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
u
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
u
power tool and positioned for maximum
English
safety, so the least amount of wheel is ex-
posed towards the operator. The guard helps
to protect operator from broken wheel frag-
ments, accidental contact with wheel and
sparks that could ignite clothing.
Wheels must be used only for recommended
u
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 flanges that
u
are of correct size and shape for your selec-
ted 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.
Do not use worn down wheels from larger
u
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
Do not "jam" the cut-off wheel or apply ex-
u
cessive 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 break-
age.
Do not position your body in line with and be-
u
hind the rotating wheel. When the wheel, at
