• Hold the power tool by insulated gripping surfaces only,
when performing an operation where the cutting
accessory may contact hidden 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 accessory 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 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
accumulation of powdered metal may cause electrical
hazards.
• Do not operate the power tool near flammable
materials. Sparks could ignite these materials.
• Do not use accessories that require liquid coolants.
Using water or other liquid coolants may result in
electrocution or shock.
Kickback and Related Messages
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 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.
• Never place your hand near the rotating accessory.
Accessory may kickback over your hand.
• 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.
• 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.
• Do not attach a saw chain woodcarving blade or
toothed saw blade. Such blades create frequent kickback
and loss of control.

Safety Warnings Specific for Grinding and
Abrasive Cutting-Off Operations
• 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.
• The grinding surface of centre depressed 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 power tool
and positioned for maximum safety, so the least
amount of wheel is exposed towards the operator. The
guard helps to protect the operator from broken wheel
fragments, accidental contact with wheel and sparks that
could ignite clothing.
• 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.
• Always use undamaged wheel flanges that are of
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.
• 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 Specific for Abrasive
Cutting-Off Operations:
• 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.
• 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.
• 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.
• 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 workpiece.
• 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.
• 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.
