Safety Rules for Corded Angle Grinders
q. Do not use accessories that require liquid
coolants. Using water or other liquid cool-
ants may result in electrocution or shock .
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 un-
der these conditions .
Kickback is the result of power tool misuse and/
or incorrect operating procedures or conditions
and can be avoided by taking proper precau-
tions 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. Al-
ways 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 .
b. Never place your hand near the rotating ac-
cessory. 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 op-
posite to the wheel's movement at the point
of snagging .
d. Use special care when working corners,
sharp edges, etc. Avoid bouncing and snag-
ging the accessory. Corners, sharp edges or
bouncing have a tendency to snag the rotat-
ing accessory and cause loss of control or
kickback .

e. Do not attach a saw chain woodcarving
blade, segmented diamond wheel with a pe-
ripheral gap greater than 10 mm (13/32") or
toothed saw blade. Such blades create fre-
quent kickback and loss of control .
3. Safety warnings specific for
grinding and cutting-off opera-
tions
a. Use only wheel types that are specified for
your power tool and the specific guard de-
signed for the selected wheel. Wheels for
which the power tool was not designed can-
not be adequately guarded and are unsafe .
b. The grinding surface of center 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 maxi-
mum 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 specified ap-
plications. For example: do not grind with
the side of cut-off wheel. Abrasive cut-off
wheels are intended for peripheral grind-
ing, side forces applied to these wheels may
cause them to shatter .
e. Always use undamaged wheel flanges that
are of correct size and shape for your se-
lected wheel. Proper wheel flanges support
the wheel thus reducing the possibility of
wheel breakage . Flanges for cut-off wheels
may be different from grinding wheel flanges.
f. Do not use worn down wheels from larger
power tools. A wheel intended for larger
power tool is not suitable for the higher
speed of a smaller tool and may burst .
g. When using dual purpose wheels always
use the correct guard for the application
being performed. Failure to use the correct
guard may not provide the desired level of
guarding, which could lead to serious injury .
