your operation. Prolonged exposure to high
intensity noise may cause hearing loss.
i) Keep bystanders a safe distance away from
the work area. Anyone entering the work area
must wear personal protective equipment.
Fragments of a workpiece or broken accessory may
fly off and result in injury beyond the immediate area
of operation.
j) Hold the 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 could give the
operator an electric shock.
k) Position the cord clear of the rotating
accessory. If you lose control, the cord may be cut
or snagged and your hand or arm may be pulled into
the rotating accessory.
l)) Never lay the power tool down until the
accessory has come to a complete stop. The
rotating accessory may grab the surface and pull
the power tool out of your control.
m) Do not run the power tool while carrying it at
your side. Accidental contact with a rotating
accessory could snag your clothing, pulling the
accessory into your body.
n) Regularly clean the power tool's air vents.
The motor's fan will draw the dust inside the housing
and an excessive accumulation of powdered metal
may cause electrical hazards.
o) Do not operate the power tool near
flammable materials. Sparks could ignite these
materials.
p) 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 sanding wheel, backing pad, brush or any
other accessory. Pinching or snagging causes the
rotating accessory to stall rapidly, This in turn
causes the uncontrolled power tool to be forced in
the opposite direction from which the accessory is
rotating at the pinched or snagged point.
For example, if an abrasive wheel is snagged or
pinched by the workpiece, the edge of the wheel
entering the pinch point can dig into the surface of
the material causing the wheel to climb out or kick
out. The abrasive wheel may either jump toward or
away from the operator, depending on direction the
disc is moving at the pinch point. Abrasive wheels
may also break under these conditions.
Kickback is the result of power tool misuse and/or
incorrect operating procedures or conditions It can
be prevented if suitable precautionary measures
are taken as described below.
a) Maintain a firm grip on the power tool and
position your body and arms to allow you to
resist kickback forces. Always use side handle,
if provided, for maximum control over kickback
or torque reaction during start-up. The operator

can control upward kickback forces, if proper
precautions are taken.
b) Never place your hand near rotating
accessories. Accessory may kickback over your
hand.
c) Do not position your body in the area where
the 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 or toothed saw blade. Such blades create
frequent kickback and can cause you to lose
control.
4.3 Safety Warnings Specific for Grinding
and Cut-Off Grinding:
a) 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.
b) The grinding surface of the centre depressed
wheels must be mounted below the plane of
the guard lip. An improperly mounted grinding
wheel that projects through the plane of the guard
lip cannot be adequately guarded.
c) The guard must be securely attached to the
power tool and positioned for maximum safety
so that the least amount of wheel is exposed
towards the operator. The guard helps to protect
the operator from broken wheel fragments and
accidental contact with the wheel and sparks which
could ignite clothing.
d) Grinding media must be used only for
recommended applications. For example: Do
not grind with the side of cutting disc. Cutting
discs are intended for peripheral grinding, Applying
force to the sides of these discs may cause them to
shatter.
e) Always use undamaged wheel flanges that
are the correct size and shape for your selected
grinding wheel. Proper wheel flanges support the
grinding wheel, reducing the possibility of
breakage. Flanges for cutting discs may be different
from grinding wheel flanges.
f) Do not use worn down grinding wheels from
larger power tools. Grinding wheels intended for
larger power tools are not suitable for the higher
speed of a smaller tool and may break.
4.4 Safety Warnings Specific for Sanding
Operations:
a) Do not use excessively large sanding disc
paper. Follow the manufacturers
recommendations when selecting sandpaper.
Larger sandpaper that extends beyond the sanding
pad presents a laceration hazard and may cause
