MACHINE-SPECIFIC SAFETY WARNINGS

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 workshop 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 accessory may fly away and
cause injury beyond immediate area of operation.
l. Hold 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
accessory.
n. Never lay the power tool down until the accessory
has come to a complete stop. The spinning
accessory 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 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. 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,
segmented diamond wheel with a peripheral gap
greater than 10 mm or toothed saw blade. Such
blades create frequent kickback and loss of control.
f. Do not "jam" a cut-off 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 snagging of
the wheel in the cut and the possibility of kickback or
wheel breakage.
g. When wheel is binding or when interrupting a cut
for any reason, switch off the power tool and hold
the power tool motionless until the wheel comes
