in accordance with these instructions and in the

manner intended for the particular type of power

tool, taking into account the working conditions

and the work to be performed. Use of the power

tool for operations different from those intended

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.

b) The substitution of the brushes of the power tool

should be accomplished by an authorized and

qualified technical service. Brushes out of

specification can cause damages to the motor of the

power tool.

Safety warnings that are common for

grinding, sanding, wire brushing, polishing

and abrasive cutting off operations:

a) This power tool is intended to function as a

grinder, sander, wire brush, polisher 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) 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.

c) 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 fly apart.

d) The outside diameter and the thickness of your

accessory must be within the capacity rating of

your power tool. Incorrectly sized accessories

cannot be adequately guarded or controlled.

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

wheels for chips and cracks, backing pads for

cracks, tear or excess wear, wire brushes for

loose or cracked wires. If the 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 shop 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 the

workpiece or of a broken accessory may fly away

and cause injury beyond the immediate area of

operation.

i) Hold the power tool only by the insulated

gripping surfaces when performing an operation

where the cutting tool may contact hidden wiring

or its own power cord. Contact with a "live" wire

will also 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.

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.

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.
