ENGLISH

e) The arbour size of wheels, flanges, backing

pads or any other accessory must properly

fit the spindle of the power tool. Accessories

with arbour holes that do not match the

mounting hardware of the power tool will run

out of balance, vibrate excessively and may

cause loss of control.

f) Do not use a damaged accessory. Before

each use inspect the accessory such as

abrasive wheel 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.

g) Wear personal protective equipment.

Depending on application, use face

shield, safety 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 operation. Prolonged

exposure to high intensity noise may cause

hearing loss.

h) 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.

i) 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.

j) 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.

k) 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.

l) 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.

m) Regularly clean the power tool’s air vents.

The motor’s fan will draw the dust inside

the housing and excessive accumulation of

powered metal may cause electrical hazards.

n) Do not operate the power tool near

flammable materials. Sparks could ignite these

materials.

o) Do not use accessories that require liquid

coolants. Using water or other liquid coolants

may result in electrocution or shock.

Safety Warnings Speciﬁ c 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.

c) Wheels must be used only for recommended

applications. For example: do not grind with

the side of cut-off wheel. Abrasive cut-off

wheels are intended for peripheral grinding, side

forces applied to these wheels may cause them

to shatter.

d) Always use undamaged wheel flanges

that are of correct size and shape for your

selected wheel. Proper wheel flanges support

the wheel thus reducing the possibility of wheel

breakage. Flanges for cut-off wheels may be

different from grinding wheel flanges.

e) Do not use worn down wheels from larger

power tools. Wheel intended for larger power

tool is not suitable for the higher speed of a

smaller tool and may burst.

Causes and Operator Prevention

of Kickback

• Kickback is a sudden reaction to a pinched,

bound or misaligned wheel, wire brush or flap
