Kickback And Related Warnings - DeWalt DCG406 Original Instructions Manual

c ) Do not convert this power tool to operate in a way
which is not specifically designed and specified by the tool
manufacturer. Such a conversion may result in a loss of control
and cause serious personal injury.
d ) Do not use accessories which are not specifically
designed and specified by the tool manufacturer. Just
because the accessory can be attached to your power tool, it does
not assure safe operation.
e ) The rated speed of the accessory must be at least
equal to the maximum speed marked on the power tool.
Accessories running faster than their rated speed can break and
fly apart.
f ) The outside diameter and the thickness of your accessory
must be within the capacity rating of your power tool.
Incorrectly sized accessories can not be adequately guarded
or controlled.
g ) The dimensions of the accessory mounting must fit the
dimensions of the mounting hardware of the power tool.
Accessories that do not match the mounting hardware of the
power tool will run out of balance, vibrate excessively and may
cause loss of control.
h ) Do not use a damaged accessory. Before each use
inspect the accessory such as abrasive wheel for chips and
cracks, backing pad for cracks, tear or excess wear, wire
brush for loose or cracked wires. If power tool or accessory
is dropped, inspect for damage or install an undamaged
accessory. After inspecting and installing an accessory,
position yourself and bystanders away from the plane of
the rotating accessory and run the power tool at maximum
no-load speed for one minute. Damaged accessories will
normally break apart during this test time.
i ) Wear personal protective equipment. Depending on
application, use face shield, safety goggles or safety glasses.
As appropriate, wear dust mask, hearing protectors, gloves
and workshop apron capable of stopping small abrasive or
workpiece fragments. The eye protection must be capable of
stopping flying debris generated by various operations. The dust
mask or respirator must be capable of filtrating particles generated
by your operation. Prolonged exposure to high intensity noise may
cause hearing loss.
j ) Keep bystanders a safe distance away from work
area. Anyone entering the work area must wear personal
protective equipment. Fragments of workpiece or of a broken
accessory may fly away and cause injury beyond immediate area
of operation.
k ) Hold the power tool by insulated gripping surfaces only,
when performing an operation where the cutting tool may
contact hidden wiring. Contact with a "live" wire will also make
exposed metal parts of the power tool "live" and could give the
operator an electric shock.
l ) 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 accessory.
m ) 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.
n ) 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.
o ) 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.
p ) Do not operate the power tool near flammable
materials. Sparks could ignite these materials.
q ) Do not use accessories that require liquid coolants. Using
water or other liquid coolants may result in electrocution or shock.
FURTHER SAFETY INSTRUCTIONS FOR ALL
OPERATIONS

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 tool misuse and/or incorrect operating
procedures or conditions and can be avoided by taking proper
precautions as given below:
a ) Maintain a firm grip with both hands on the power tool
and position your body and arms 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 reaction or kickback
forces, if proper precautions are taken.
b ) Never place your hand near the rotating accessory.
Accessory may kickback over your hand.
c ) 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.
d ) 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.
e ) Do not attach a saw chain woodcarving blade,
segmented diamond wheel with a peripheral gap greater
than 10 mm or toothed saw blade. Such blades create frequent
kickback and loss of control.
Safety Warnings Specific for Grinding and Cutting-
Off Operations
a ) Use only wheel types that are specified 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.
b ) 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.
c ) 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.
d ) Wheels must be used only for recommended
applications. For example: do not grind with the side of
