capable of stopping small abrasive or work piece 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.
i) Keep bystanders a safe distance away from work area.
Anyone entering the work area must wear personal protective
equipment. Fragments of work piece 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" w ire 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 work
piece, 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 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.
