Position the cord clear of the spinning accessory. If you
lose control of the power tool, the cord may be cut or
snagged and your hand or arm may be pulled into the
spinning accessory.
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 con-
trol.
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 warnings
Kickback is a sudden reaction to a pinched or snagged
rotating wheel, backing pad, brush or any other acces-
sory. 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 mate-
rial 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 incor-
rect 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 over the power tool.
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 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,
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 the cut-off
wheel.
Abrasive cut-off wheels are intended for periph-
eral 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 differ-
ent 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 pres-
sure. Do not attempt to make an excessive depth of cut.
Overstressing the wheel increases the loading and sus-
ceptibility 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 opera-
tion, is moving away from your body, the possible kick-
back 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 work-
pieces 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 exist-
ing walls or other blind areas.
The protruding wheel may
cut gas or water pipes, electrical wiring or objects that can
cause kickback.
