CUT-OFF MACHINE SAFETY WARNINGS
a) The guard provided with the tool must be securely
attached to the power tool and positioned for
maximum safety, so the least amount of wheel is
exposed towards the operator. Position yourself and
bystanders away from the plane of the rotating
wheel.
The guard helps to protect operator from broken
wheel fragments and accidental contact with wheel.
b) Use only bonded reinforced or diamond cut-off
wheels for your power tool.
Just because an accessory can be attached to your
power tool, it does not assure safe operation.
c) The rated speed of the accessory must be at least
equal to the maximum speed marked on the power
tool.
Accessories running faster than their rated speed can
break and fly apart.
d) Wheels must be used only for recommended
applications. For example: do not grind with the side
of 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 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 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.

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.
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 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.
a) 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.
b) Never place your hand near the rotating accessory.
Accessory may kickback over your hand.
c) Do not position your body in line with the rotating
wheel.
