into account the working conditions and the

work to be performed.

Use of the power tool for

operations different from those intended could result

in a hazardous situation.

5) Service

a )

Have your power tool serviced by a qualified

repair person using only identical replacement

parts.

This will ensure that the safety of the power

tool is maintained.

ADDITIONAL SPECIFIC SAFETY RULES

Safety Instructions for All Operations

a )

This power tool is intended to function as a

grinder, sander, wire brush or cut-off tool. Read

all safety warnings, instructions, illustrations

and specifications provided with this power tool.

Failure to follow all instructions listed below may

result in electric shock, fire and/or serious injury.

b )

Operations such as polishing are not

recommended to be performed with this power

tool.

Operations for which the power tool was not

designed may create a hazard and cause personal

injury.

c )

Do not use accessories which are not specifically

designed and recommended by the tool

manufacturer.

Just because the accessory can be

attached to your power tool, it does not assure safe

operation.

d )

The rated speed of the accessory must be at least

equal to the maximum speed marked on the

power tool.

Accessories running faster than their

rated speed can break and fly apart.

e )

The outside diameter and the thickness of your

accessory must be within the capacity rating of

your power tool.

Incorrectly sized accessories can

not be adequately guarded or controlled.

f )

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.

g )

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.

h )

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.

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 could give the operator an electric shock.

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.

FURTHER SAFETY INSTRUCTIONS FOR ALL

OPERATIONS

Causes and Operator Prevention of

Kickback

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
