do not grind with the side of cut-off
wheel. 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 reducing the
possibility of wheel breakage
f) Do not use worn down reinforced wheels
from larger power tools. Wheels intended
for a larger power tool are not suitable for the
higher speed of a smaller tool and may burst.
g) 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.
h) The arbour size of wheels and flanges
must properly fit the spindle of the power
tool. Wheels and flanges with arbour 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.
i) Do not use damaged wheels. Before
each use, inspect the wheels for chips
and cracks. If 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.
Damaged wheels will normally break apart
during this test time.
j) Wear personal protective equipment.
Depending on application, use face
shield, safety goggles or safety glasses.
As appropriate, wear dust mask, hearing
protectors, gloves and shop apron
capable of stopping small workpiece
fragments. The eye protection must be
cap-able 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.
k)
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.
l) 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.
m) 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 wheel.
n) Never lay the power tool down until the
accessory has come to a complete stop.
The spinning wheel may grab the surface and
pull the power tool out of your control.
o) 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.
p) 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.
q) Do not operate the power tool near
flammable materials. Sparks could ignite
these materials.
r) Do not use accessories that require
liquid coolants. Using water or other liquid
coolants may result in electrocution or shock.
FURTHER SAFETY INSTRUCTIONS FOR CUTTING-OFF
OPERATIONS 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
power tool to be forced in the direction
opposite of the wheel’s rotation at the point
of the binding.
For example, if a 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. 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.
a) Maintain a firm grip on the power tool
and position your body and arm to allow
you to resist kickback forces. Always use
