1_MACHINE-SPECIFIC SAFETY
WARNINGS
1.1 SAFETY WARNINGS COMMON FOR
GRINDING, SANDING, WIRE BRUSHING OR
ABRASIVE CUTTING-OFF OPERATIONS
This power tool is intended to function as a grin-
der, sander, wire brush or cut-off tool. Read all
safety warnings, instructions,
illustrations and spe-
cifications provided with this power tool. Failure to fo
-
llow all instructions listed below may result in electric
shock, fire and/or serious injury
.
This power tool is not recommended for polishing.
Operations for which the power tool was not designed
may create a hazard and cause personal injury.
Do not use accessories which are not specifically
designed and recommended by the tool
manufacturer
. Just because the accessory can be
attached to your power tool, it does not assure safe
operation.
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.
The outside diameter and the thickness of your
accessory must be within the capacity rating of
your power tool
. Incorrectly sized accessories cannot
be adequately guarded or controlled.
The arbor size of wheels, flanges, backing pads or
any other accessory must properly fit the spindle
of the power tool.
Accessories with arbor holes that
do not match the mounting hardware of the power tool
will run out of balance, vibrate excessively and may
cause loss of control.
Do not use a damaged accessory. Before each use,
inspect the accessory such as abrasive wheels for
chips and cracks, backing pads for cracks, tears
or excess wear, wire brushes 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.
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.
Keep bystanders a safe distance away from the
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.
Hold the power tool only by the insulated gripping
surfaces when performing an operation where the
cutting accessory may contact hidden wiring or its
own cord.
Contact with a “live” wire will also 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 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.
1.2 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.
