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.
