Keep bystanders a safe distance away from work area. Any-
one entering the work area must wear personal protective
equipment. Fragments of workpiece or of a broken acces-
sory may fly away and cause injury beyond immediate
area of operation.
Hold power tool by insulated gripping surfaces only, when
performing an operation where the cutting accessory may
contact hidden wiring or its own cord. Cutting accessory
contacting a "live" wire may make exposed metal parts of
the power tool "live" and shock the operator.
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 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 accumu-
lation 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. Acces-
sory 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.
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 can-
not 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 acci-
dental contact with wheel.
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 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 pressure.
Do not attempt to make an excessive depth of cut. Over-
stressing the wheel increases the loading and susceptibil-
ity 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. Investi-
gate 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.
