For your own protection and for the

protection of your power tool, pay

attention to all parts of the text that are

marked with this symbol!

WARNING – Reading the operating

instructions will reduce the risk of injury.

WARNING Read all safety warnings and

instructions. Failure to follow all safety

warnings and instructions may result in electric

shock, fire and/or serious injury.

Keep all safety instructions and information for

future reference.

Pass on your power tool only together with these

documents.

4.1 Safety instructions for sanding:

Use

a) This power tool is intended to function as a

sander. Read all safety 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) This power tool is not suitable for polishing

or tasks using roughing discs, wire brushes or

parting sanding discs. 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 external diameter and thickness of your

accessory must be within the capacity rating of

your power tool. Incorrectly sized accessories

cannot be adequately guarded or controlled.

f)

Threaded mounting of accessories must

match the sanding 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

sanding wheels for chips and cracks, the

backing pad for cracks, tear or excess wear

and the wire brush 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 the

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. Use a

face shield, safety goggles or safety goggles

depending on the application. As appropriate,

wear a dust mask, hearing protectors, gloves

and a 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 filtering 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 a workpiece or broken accessory may fly away

and cause injury beyond the immediate area of

operation.

j) Hold the power tool by the insulated gripping

surfaces only when performing an operation

where the accessory may contact hidden

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

may make exposed metal parts of the power tool

"live" and shock the operator.

k) Position the cord clear of the rotating

accessory. If you lose control, the cord may be cut

or snagged and your hand or arm may be pulled into

the rotating accessory.

I) Never lay the power tool down until the

accessory has come to a complete stop. The

rotating 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 rotating

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.

4.2 Kickback and related warnings

Kickback is a sudden reaction to a pinched or

snagged sanding wheel, backing pad, brush or any

other accessory. Pinching or snagging causes rapid

stalling of the rotating accessory. This 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 a sanding 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 sanding wheel may either jump

towards or away from the operator depending on

direction of the wheel’s movement at the point of

pinching. Sanding wheels may also break under

these conditions.

Kickback is the result of power tool misuse and/or

incorrect operating procedures or conditions. It can

be prevented if suitable precautionary measures

are taken as described below.

a) Maintain a firm grip on the power tool and

position your body and arm to allow you to

resist kickback forces. Always use the

additional handle, if provided, for maximum

control over kickback or a torque reaction

during start-up. The operator can control torque

reactions or kickback forces if proper precautions

are taken.

b) Never place your hand near the rotating

accessory. The accessory may kickback over your

hand.

c) Do not position your body in the area where

the power tool will move if kickback occurs.

Kickback will propel the tool in direction opposite to

the wheel’s movement at the point of snagging.

d)

Use special care when working in corners,

on sharp edges etc. Avoid bouncing and

snagging the accessory. Corners, sharp edges or

bouncing have a tendency to snag the rotating

accessory and cause loss of control or kickback.

e) Do not attach a saw chain woodcarving

blade or toothed saw blade. Such blades create

frequent kickback and loss of control.

4.3 Safety warnings specific for sanding

operations:

a) Do not use excessively oversized sanding

disc paper. Follow manufacturers

recommendations when selecting sanding

paper. Larger sanding paper extending beyond the

sanding pad presents a laceration hazard and may

cause snagging, tearing of the disc or kickback.

4.4 Additional safety instructions:

WARNING – Always wear protective

goggles.

Wear a suitable dust protection mask.

Do not use bonded sanding discs.

a) Use only sanding media approved for your

guard. Sanding media for which the guard was not

designed cannot be adequately guarded and are

unsafe.

b) The safety guard must be securely attached

to the power tool. Always direct the power tool

so that the wheel is not openly exposed to the

operator. The guard helps to protect the operator

from broken fragments, accidental contact with the

sanding media and sparks that could ignite clothing.

c) Sanding media must be used only for

recommended applications.

d) Always use undamaged wheel flanges that

are the correct size and shape for your selected

accessories. The correct flanges support the

accessories.

Use elastic cushioning layers if they have been

supplied with the sanding media and if required.

Observe the specifications of the tool or accessory

manufacturer! Protect the discs from grease or

impact!

Accessories must be stored and handled with care

in accordance with the manufacturer's instructions.

Secure small workpieces. For example, clamp in a

vice.

The workpiece must lay flat and be secured against

slipping, e.g. using clamps. Large workpieces must

be sufficiently supported.

If accessories with threaded inserts are used, the

end of the spindle may not touch the base of the

hole on the sanding tool. Make sure that the thread

in the accessory is long enough to accommodate

the full length of the spindle. The thread in the

accessory must match the thread on the spindle.

See page 4 and chapter 15. Technical

Specifications for more information on the spindle

length and thread.

Use of a fixed extractor system is recommended.

Always install an RCD with a maximum trip current

of 30 mA upstream. If the angle grinder is shut down

via the RCD, it must be checked and cleaned. See

chapter 9. Cleaning.

Damaged, eccentric or vibrating tools must not be

used.

Avoid damage to gas or water pipes, electrical

cables and load-bearing walls (static).

Pull the plug out of the socket before making any

adjustments, converting or servicing the machine.

Metabo S-automatic safety clutch. When the safety

clutch responds, switch off the machine

immediately!

A damaged or cracked additional handle must be

replaced. Never operate the machine with a

defective side handle.

A damaged or cracked safety guard must be

replaced. Never operate a machine with a defective

safety guard.

Reducing dust exposure:

Some dust created by using this power tool

may contain chemicals known to cause

cancer, allergic reaction, respiratory disease, birth

defects or other reproductive harm. Some of these

substances include: lead (in paint containing lead),

mineral dust (from bricks, concrete etc.), additives

used for wood treatment (chromate, wood

preservatives), some wood types (such as oak or

beech dust), metals, asbestos.

The risk from exposure to such substances will

depend on how long you or people nearby are

exposed to them.

Do not let particles enter the body.

Do the following to reduce exposure to these

substances: ensure good ventilation of the

workplace and wear appropriate protective

equipment, such as respirators able to filter

microscopically small particles.

Observe the relevant guidelines for your material,

staff, application and place of application (e.g.

occupational health and safety regulations,

disposal).

Collect the generated particles at the source, avoid

deposits in the surrounding area.

Use suitable accessories for special work (see

chapter 12.), thus less particles enter the

environment in an uncontrolled manner.

Use a suitable extraction unit.

Reduce dust exposure with the following measures:

- Do not direct the escaping particles and the

exhaust air stream at yourself or nearby persons

or on dust deposits.

- Use an extraction unit and/or air purifiers

- Ensure good ventilation of the workplace and

keep clean using a vacuum cleaner Sweeping or

blowing stirs up dust

- Vacuum or wash protective clothing Do not blow,

beat or brush.
