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.
i) 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.
j) 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 shock the operator.
k) 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.
l) 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.
m)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.
n) 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.
o) Do not operate the power tool near
flammable materials. Sparks could ignite
these materials.
p) 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, 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 kickout. 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 the area
where power tool will move if kickback
occurs. 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 or toothed saw blade. Such blades
create frequent kickback and loss of control.
Safety Warnings Specific for Grinding and
Abrasive Cutting-Off Operations:
a) Use only wheel types that are
recommended for your power tool and
the specific guard designed for the
selected wheel. Wheels for which the
power tool was not designed cannot be
adequately guarded and are unsafe.
b) The guard must be securely attached to
the power tool and positioned for
maximum safety, so the least amount of
wheel is exposed towards the operator.
The guard helps to protect operator from
broken wheel fragments and accidental
contact with wheel.
