■ Threaded mounting of accessories
must match the grinder spindle thread.
For accessories mounted by flanges,
the arbour hole of the accessory must
fit the locating diameter of the flange.
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.
■ Do not use a damaged accessory. Before
each use inspect the accessory such as
abrasive wheels for chips and cracks,
backing pad for cracks, tear or excess
wear. 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 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.
■ 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.
■ 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
14
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 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. 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.
