d)
Wheels must be used only for recommended
applications. For example: do not grind with
the side of a cut-off wheel.Wheels must be
used only for recommended applications. For
example: do not grind with the side of a cut-off
wheel. Abrasive cut-off wheels are intended for
peripheral grinding, side forces applied to these
wheels may cause them to shatter.
e)
Always use undamaged wheel flanges that are
of correct diameter for your selected wheel.
Proper wheel flanges support the wheel thus re-
ducing the possibility of wheel breakage.
f)
The outside diameter and the thickness of
your accessory must be within the capacity
rating of your power tool. Incorrectly sized ac-
cessories cannot be adequately guarded or con-
trolled.
g)
Grinding discs and flanges must fit exactly on
your electrical tool's grinding spindle. Inser-
tion tools that do not fit exactly on your electrical
tool's grinding spindle rotate unevenly, vibrate
very strongly and can cause a loss of control.
h)
Do not use damaged wheels. Before each use,
inspect the wheels for chips and cracks. If the
power tool or wheel is dropped, inspect for
damage or install an undamaged wheel. After
inspecting and installing the wheel, position
yourself and bystanders away from the plane
of the rotating wheel and run the power tool at
maximum no load speed for one minute. Dam-
aged wheels will normally break apart during this
test time.
i)
Wear personal protective equipment. De-
pending on application, use face shield, safe-
ty goggles or safety glasses. As appropriate,
wear dust mask, hearing protectors, gloves
and shop apron capable of stopping small
abrasive or workpiece fragments. The eye pro-
tection 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 wheel may
fly away and cause injury beyond immediate area
of operation.

k)
Keep the power cable away from rotating in-
sertion tools. If you lose control, the cord may
be cut or snagged and your hand or arm may be
pulled into the spinning wheel.
l)
Regularly clean the power tool's air vents. The
motor's fan can draw the dust inside the housing
and excessive accumulation of powdered metal
may cause electrical hazards.
m) Do not operate the power tool near flamma-
ble materials. Do not operate the power tool
while placed on a combustible surface such
as wood. Sparks could ignite these materials.
n)
Do not use accessories that require liquid
coolants. Using water or other liquid coolants
may result in electrocution or shock.
2) Kickback and related warnings
Kickback is a sudden reaction to a pinched or snagged
rotating wheel. Pinching or snagging causes rapid
stalling of the rotating wheel which in turn causes the
uncontrolled cutting unit to be forced upwards toward
the operator.
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 sur-
face of the material causing the wheel to climb out
or kick out. Abrasive wheels may also break under
these conditions. Kickback is the result of incorrect or
deficient use of the electrical tool. It can be prevented
by suitable precautionary measures, as described in
the following.
a)
Maintain a firm grip on the power tool and po-
sition your body and arm to allow you to resist
kickback forces. The operator can control upward
kickback forces, if proper precautions are taken.
b)
Do not position your body in line with the ro-
tating wheel If kickback occurs, it will propel the
cutting unit upwards toward the operator.
c)
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.
d)
Do not "jam" the wheel or apply excessive
pressure. Do not attempt to make an excessive
depth of cut. Overstressing the wheel increases
the loading and susceptibility to twisting or bind-
ing of the wheel in the cut and the possibility of
kickback or wheel breakage.
