out of balance, vibrate excessively and may

cause loss of control.

Do not useadamaged accessory. Before

each use

inspect

the accessory such as abrasive wheel for chips and cracks, backing pad for

crecks,

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. Atter inspecting and instal/ing an accessory, position yourself and bystanders away from the piane of the rotating accessory and run the power tool at maximum no-loed speed

for one minute.

Damaged accessories will

normally break apart during this test time.

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 smallabrasive 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 expoeote to high intensity noise may

cause hearing loss.

Sparks could ignite

these materia/s.

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 isasudden reaction toapinched or snagged rotating wheel, backing pad, brush or any other

accessory.

Pinching or snagging

causes

rapid stalling of the rotating accessory which in turn cause;' the uncontrolled power tool to be forced in

Page 3

ENGLlSH

the direclion opposite of the accessory's rotation at the point of the bindlng.

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 l17to 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 whee/'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 glven below:

Maintain a firm grip on the power tool and position your body and arm to allo w you to resist kickback forces. Always use auxiliary handle, if provided, for maximum control over kickback or torque reaction during start up. The operator can control

torque reaction or kickback forces, If proper precautions are taken.

b) Never piace your hand near the rotating

accessory. Accessory may klckback over your

hand.

c) Do not position your body in the area

where power tool will move if kickback occurs. Kickback wlll propel the tool

direction

opposite to the wheel's movement at

tre

point

of snagging,

d) Use special care when working corners,

sharp edges etc. Avoid bouncing and snagging the accessory. Comers, sharp

edges or bounclng have a tendency to snag the rotating accessory and cause loss of control or klckback.

e) Do not attach a saw chain woodcarving

biade or toothed saw biade. Such blades

create frequent kickback and loss of control.

Safety Warnings Specific for Grinding and Abrasive Cutting-Off Operations

Use only wheel types that are recommended for your power tool and the specific guard designed for the selected wheel. Whee/s 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 the operator from broken wheel fragments, accidental contact wlth wheel and sparks that could ignite clothing.

Whee/s 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 grindlng, slde forces applied to these whee/s may cause them to shatler.

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.

Do not use worn down wheels from larger power too/s. Wheel intended for larger power

tool is not suitable far the hlgher speed of a smaller tool and may burst.

Additional Safety Warnings Specific for Abrasive Cutting-Off Operations

a) Do not ''jam'' the cut-off wheel or app/y

excessive pressure. Do not attempt to make an excessive depth of cut.

Overstressing the wheel increases the loading and susceptibility to twisting or binding of the wheel in the cut and the possibility of kickback or wheel breakage.

b) Do not position your body in line with and

behind the rotating wheel. When the wheel,

at the point of operations, is moving away from your body, the possible kickback may propel the spinning wheel and the power tool directiy

you.

When wheel is binding or when interrupting a

cut

for any reason, switch off the power tool and hold the power tool motionless unti! the wheel comes to a complete stop. Never attempt to remove the cut-off wnee! from the cut while tfÌe wheel is in motion btherwise kickback may occur. Invesligate and take corrective action to

eliminate the cause of wheel binding.

d) Do not restart the cutting operation in the

workpiece. Let the wheel reach full speed and carefully reenter the cut. The wheel may

bind, walk up or kickback if the power tool is restarted in the workpiece.

ENGlISH

Support panels or any oversized workpiece to minimize the risk of wheel pinching and kickback. Large workpieces tend to sag under

their own weight. Supports must be placed

under the workpiece near the line of cut and near the edge of the workpiece on both sides ot

the wheel.

~ Use extra caution when making a "pocket

cui" into existing walls or other blind areas.

The protruding wheel may cut gas or water

pipes, electrical wiring or objects that can cause

kickback.

Safety Warnings Specific far Sanding Operations

DWE4557, DWE4597 ONLY

Do not use excessively oversized sanding disc paper. Follow manufacturer's recommendations, when selecting sanding paper. Larger sanding paper extending beyond

the sanding pad presents a laceralion hazard and may cause snagging, tearing of the disc or kickback.

Safety Warnings Specific for Wire

Brushing Operations

Be aware that wire bristles are thrown by the brush even during ordinary operation. Do not overstress the wires by applying excessive loadrothe brush. The wire bristies

can easi/y penetrate lighl clothing and/or skin.

b) /f the use of a guard is recommended

for wire brushing, do not allow any

interference of the wire wheel or brush

with the guardo Wire wheel or brush may

expand in diameter due to work load and centrifugai forces.

Additional Safety Rules far Grinders

• Threaded mounting of accessories must match the grinder spindle thread. For accessories mounted by flanges, the arbor hole of the

accessory must fit the locating diameter of

the flange. Accessories thal do not match the mounling hardware of the power tool will run out of balance, vibrate excesslvely and may cause loss of control.

o The grinding surface of the centte depressed

whee/s must be mounled below the piane of the guard lip. An improperly mounted wheel that projects through the piane of the guard lip cannot be adequately prolected.

• Do not use Type 11 (flaring cup) wheels on this too/. Using inappropriate accessories can

result

lil

injU/y

• A/ways use side handle. Tighten the handle securely. The side handle should always be

used to maintain contrai of the tool at ali times.

Residual Risks

In spite of the application of the relevant safety regulations and the implementation of safety devices, certain residual risks cannot be avoided. These are.

- Impairment of hearing. Risk of personal injury due to f/ying particles.

- Risk of burns due to accessories becoming hot during operation.

WARNING:

In extreme working

ili

conditions, conductive dust can accumulate inside the machine housing when working with metal. This can result in the protective insulation inthe machine becoming degraded withapotential risk of an electrical shock.

To avoid build-up of metal swarf inside the machine, we recommend to clear the ventilation slots on a daily basis. Refer to

Maintenance.

Cutting Metal

For cutting with bonded abrasives, always use a protection guarèl type 1.

When cutting, work with moderate feed, adapted to the material being cut. Do not exert pressure onto the cutting disc, tilt or oscillate the machine.

Do not reduce the speed of running down cutting discs by applying sideward pressure.

The machine must always work in an upgrinding motion. Otherwise, the danger exists of it being pushed uncontrolled out of the cut.

When cutting profiles and square bar, it is best to

start at the smallest cross section.

Rough Grinding

Never use a cutting disc for roughing. Always use the guard type 27.

The best roughing results are achieved when setting the machine at an angle of 30° to 40°. Move the machine back and forth with moderate pressure. In this manner, the workpiece will not become too hot, does not discolour and no grooves are formed.

Cutting Stone

The machine shall be used only for dry cutting.

For cutting stone,

itìsbest to use a diamond

cutting disco Operate the machine bnly with

additional dust protection mask.

Working Advice

Exercise caution when cutting slots in structural walls.

Slots in structural walls are subject to the country- specific regulations. These regulations are to be observed under ali circumstances. Before beginning work, consult the responsible structural engineer,

architect or the construction supervisor.

Using Flap Discs

----IA..-

WARNING: Metal d!!st build-up.

ill

Extensive use of flap discs in metal applications can result in the increased

potential for electric shock. To reduce

this risk, insert an RCO before use and c1ean the ventilation s/ots daily by blowing dry compressed air into the ventilation s/ots inaccordance with the below maintenance instructlon»,
