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.
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.
The accessory may kickback over your hand.
Do not position your body in the area where the
power tool will move if kickback occurs. Kickback will
propel the tool in the 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 over the power tool.
Additional safety instructions for grinding and
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 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.

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.
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. Wheels intended for larger power tools are 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 reenter
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.
Safety warnings specific for sanding operations
Do not use excessively oversized sanding disc paper.
Follow manufacturers recommendations, when
selecting sanding paper. Larger sanding paper
extending beyond the sanding pad presents a laceration
hazard and may cause snagging, tearing of the disc, or
kickback.
