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 (DWE4238 is excluded), 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 and sanding

(DWE4238) 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 ) Threaded mounting of accessories must match the

grinder spindle thread. For accessories mounted by

flanges, the arbour hole of the accessory must fit the

locating diameter of the flange. Accessories 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 the 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 electrical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.

q ) Do not use Type 11 (flaring cup) wheels on this tool.

Using inappropriate accessories can result ininjury.

r ) Always use side handle. Tighten the handle securely.

The side handle should always be used to maintain control

of the tool at alltimes.

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
