f Do not use a damaged accessory. Before

each use inspect the accessory such as abra-

sive wheels for chips and cracks, backing

pad for cracks, tear or excess wear, wire

brush for loose or cracked wires. If power

tool or accessory is dropped, inspect for

damage or install an undamaged accessory.

After inspecting and installing an accessory,

position yourself and bystanders away from

the plane of the rotating accessory and run

the power tool at maximum no-load speed

for one minute. Damaged accessories will

normally break apart during this test time.

f Wear personal protective equipment. De-

pending on application, use face shield, safe-

ty 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 oper-

ation. Prolonged exposure to high intensity

noise may cause hearing loss.

f 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 acces-

sory may fly away and cause injury beyond im-

mediate area of operation.

f Hold power tool by insulated gripping sur-

faces only, when performing an operation

where the cutting accessory may contact

hidden wiring or its own cord. Cutting acces-

sory contacting a “live” wire may make ex-

posed metal parts of the power tool “live” and

shock the operator.

f Position the cord clear of the spinning acces-

sory. If you lose control of the power tool, the

cord may be cut or snagged and your hand or

arm may be pulled into the spinning accesso-

ry.

f Never lay the power tool down until the ac-

cessory has come to a complete stop. The

spinning accessory may grab the surface and

pull the power tool out of your control.

f Do not run the power tool while carrying it at

your side. Accidental contact with the spin-

ning accessory could snag your clothing, pull-

ing the accessory into your body.

f Regularly clean the power tool’s air vents.

The motor’s fan will draw the dust inside the

housing and excessive accumulation of pow-

dered metal may cause electrical hazards.

f Do not operate the power tool near flamma-

ble materials. Sparks could ignite these mate-

rials.

f Do not use accessories that require liquid

coolants. Using water or other liquid coolants

may result in electrocution or shock.

Kickback and related warnings

f 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 op-

erator, depending on direction of the wheel’s

movement at the point of pinching. Abrasive

wheels may also break under these condi-

tions.

Kickback is the result of power tool misuse

and/or incorrect operating procedures or con-

ditions and can be avoided by taking proper

precautions as given below.

f 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 re-

actions or kickback forces, if proper precau-

tions are taken.
