ware of the power tool will run out of balance,

vibrate excessively and may cause loss of control.

g)

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 a 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.

h)

Wear personal protective equipment.

Depending on application, use face shield,

safety goggles or safety glasses. As appro-

priate, wear dust mask, hearing protectors,

gloves and workshop apron capable of stop-

ping 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 filtering

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.

A cutting acces-

sory contacting a "live" wire may make exposed

metal parts of the power tool "live" and give the

operator an electric shock.

k)

Position the cord clear of the spinning acces-

sory.

If you lose control, the cord may be cut or

snagged and your hand or arm may be pulled into

the spinning accessory.

I)

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 flam-

mable materials.

Sparks could ignite these mate-

rials.

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 the auxiliary

handle, if provided, for maximum control over

kickback or torque reaction during start-up.

The operator can control torque reactions or kick-

back 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 move-

ment 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.

4.3

Safety Warnings Specific for Grinding

and 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.
