power tool at maximum no-load speed for one minute.

Damaged accessories will normally break apart during

this test time.

h) Wear personal protective equipment. Depending on

application, use face shield, safety goggles or safety

glasses. As appropriate, wear dusk 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.

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 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.
