cord. Cutting accessory contacting a “live”
wire may make exposed metal parts of the
power tool “live” and could give the opera-
tor an electric shock.
► Position the cord clear of the spinning
accessory. If you lose control, the cord
may be cut or snagged and your hand or
arm may be pulled into the spinning wheel.
►
Never lay the power tool down until
the accessory has come to a complete
stop. The spinning wheel may grab the
surface and pull the power tool out of your
control.
►
Do not run the power tool while carry-
ing it at 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. The motor’s fan will draw the dust
inside the housing and excessive accumu-
lation of powdered metal may cause elec-
trical hazards.
►
Do not operate the power tool near
fl ammable materials. Sparks could ignite
these materials.
► Do not use accessories that require
liquid coolants. Using water or other liq-
uid coolants may result in electrocution or
shock.
Kickback and Related Warnings
► Kickback is a sudden reaction to a pinched
or snagged rotating wheel. Pinching or
snagging causes rapid stalling of the
rotating wheel which in turn causes the
uncontrolled power tool to be forced in the
direction opposite of the wheel’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 oper-
ating procedures or conditions and can be
avoided by taking proper precautions as
given below.
► Maintain a firm grip on the power tool
and position your body and arm to
allow you to resist kickback forces. Al-
ways 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
accessory. Accessory may kickback over
your hand.
►
Do not position your body in line with
the rotating wheel. Kickback will propel
the tool in direction opposite to the wheel’s
movement at the point of snagging.
► Use special care when working cor-
ners, 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.
►
Do not attach a saw chain, woodcarving
blade, segmented diamond wheel with
a peripheral gap greater than 10mm or
toothed saw blade. Such blades create
frequent kickback and loss of control.
►
Do not “jam” the wheel or apply exces-
sive pressure.Do not attempt to make
an excessive depth of cut. Overstress-
ing the wheel increases the loading and
susceptibility to twisting or binding of the
wheel in the cut and the possibility of kick-
back or wheel breakage.
► When wheel is binding or when inter-
rupting 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 re-
move the wheel from the cut while the
wheel is in motion otherwise kickback
may occur. Investigate and take correc-
tive action to eliminate the cause of wheel
binding.
► Do not restart the cutting operation in
the workpiece. Let the wheel reach full
speed and carefully re-enter the cut.
The wheel may bind, walk up or kickback
if the power tool is restarted in the work-
piece.
► Support panels or any oversized work-
piece to minimize the risk of wheel
pinching and kickback.
Large workpieces
tend to sag under their own weight. Sup-
ports must be placed under the workpiece
near the line of cut and near the edge of
the workpiece on both sides of the wheel.
►
Use extra caution when making a
“pocket cut” into existing walls or other
blind areas. The protruding wheel may
