i) Hold the power tool by insulated gripping
surfaces only, when performing an operation
where the cutting accessory may contact
hidden wiring or its own cord. A cutting acces-
sory that comes in contact with a "live" wire may
render exposed metal parts of the power tool "live"
and give the operator an electric shock.
j) Position the cord clear of the spinning acces-
sory. If you lose control, the cord may be cut or
snagged and your hand or arm may be pulled into
the spinning accessory.
k) Never lay the power tool down until the
accessory has come to a complete stop. The
spinning accessory may grip 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 accumulation of powdered metal
may cause electrical hazards.
n) Do not operate the power tool near flam-
mable materials. Sparks could ignite these mate-
rials.
o) Do not use accessories that require liquid
coolants. Using water or other liquid coolants may
result in electrocution or shock.
3.2 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 to the accessory’s rotation at
the point of jamming.
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 condi-
tions.
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 the auxiliary
handle, if provided, for maximum control over
kickback or torque reaction during start-up.
The operator can control torque reactions or kick-
back 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. Kick-
back will propel the tool in a direction opposite to the
wheel’s movement at the point of snagging.
d) Use special care when working around
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.
3.3 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) Wheels must be used only for recommended
applications. For example: do not grind with
the side of the cut-off wheel. Abrasive cut-off
wheels are intended for peripheral grinding, side
forces applied to these wheels may cause them to
shatter.
c) Always use undamaged wheel flanges that
are the 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.
d) Do not use worn down wheels from larger
power tools. Wheels intended for larger power
tools are not suitable for the higher speed of a
smaller tool and may burst.
3.4 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
excessively deep cuts. 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) If the wheel jams or if you interrupt 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 the wheel jam.
d) Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed and
carefully reenter the cut. The wheel may jam,
walk up or kickback if the power tool is restarted in
the workpiece.
e) Support panels or any oversized workpiece
to minimise the risk of wheel pinching and kick-
