and an 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.
3.2 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 the 

rotating accessory to stall rapidly, This in turn

causes the uncontrolled power tool to be forced in

the opposite direction from which the accessory is

rotating at the pinched or snagged point. 

For example, if an abrasive wheel is snagged or

pinched by the workpiece, the edge of the wheel 

entering the pinch point can dig into the surface of

the material causing the wheel to climb out or kick

out. The abrasive wheel may either jump toward or

away from the operator, depending on direction the 

disc is moving at the pinch point. 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 if suitable precautionary measures

are taken as described below.

a) Maintain a firm grip on the power tool and 

position your body and arm so that you can 

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 a 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 the direction opposite to the 

grinding wheel’s movement at the pinch or snag

point. 

d) Use special care when working corners,

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 can cause you to lose

control. 
3.3 Safety Warnings Specific for Grinding

and Cut-Off Grinding:

a) Use only wheel types that are recommended

for your power tool and the specific guard 

designed for the selected wheel. Wheels for 

which the power tool was not designed cannot be

adequately guarded and are unsafe.

b) The grinding surface of the centre depressed 

wheels must be mounted below the plane of

the guard lip. An improperly mounted grinding

wheel that projects through the plane of the guard 

lip cannot be adequately guarded.

c) The guard must be securely attached to the 

power tool and positioned for maximum safety

so that the least amount of wheel is exposed 

towards the operator. The guard helps to protect 

operator from broken wheel fragments and 

accidental contact with the wheel and sparks which 

could ignite clothing.

d) Grinding media must be used only for 

recommended applications. 

For example: do not grind with the side of the 

cutting disc. Cutting discs are intended for 

grinding using the edge of the disc. Applying force 

to the sides of these discs may cause them to

shatter.

e) Always use undamaged wheel flanges that

are the correct size and shape for your selected 

grinding wheel. Proper wheel flanges support the 

grinding wheel, reducing the possibility of

breakage. Flanges for cutting discs may be different 

from grinding wheel flanges.

f) Do not use worn down grinding wheels from

larger power tools. Grinding wheels intended for 

larger power tools are not suitable for the higher

speed of a smaller tool and may break.
3.4 Additional Safety Warnings Specific for 

Cut-Off Grinding: 

a) Do not “jam” the cutting disc or apply 

excessive pressure. Do not attempt to make an

excessively deep cut. Overstressing the cutting

disc increases the load and makes the disc more

susceptible to twisting or bending in the cut and 

more likely to kick back and break.

b) Do not position your body in line with or

behind the rotating cutting disc. When the 

cutting disc is moving away from your body at the

point of operation, any kickback can propel the 

spinning disc and the power tool directly towards 

you.

c) If the cutting disc is stuck or when

interrupting a cut for any reason, switch off the 

power tool and hold the power tool motionless 

until the disc comes to a complete stop. Never 

attempt to remove the cutting disc from the cut 

while the disc is in motion; otherwise kickback

may occur. Investigate and take corrective action

to eliminate the cause if a disc becomes stuck.

d) Do not restart the cutting operation in the 

workpiece. Let the cutting disc reach full speed 

and carefully re-enter the cut. The wheel may 

bind, walk up or kickback if the power tool is

restarted in the workpiece.

e) Support panels or any oversized workpiece 

to minimize the risk of cutting disc pinching

and kickback. Large workpieces tend to sag under 

their own weight. Supports must be placed under 

the workpiece near the line of the cut and near the 

edge of the workpiece on both sides of the wheel.

ENGLISH en

f) Use extra caution when making "pocket cuts"

into existing walls or other blind areas. The 

protruding cutting disc may cause kickback when 

cutting gas or water pipes, electrical wiring or other 

objects.
3.5 Safety Warnings Specific for Sanding 

Operations: 

a) Do not use excessively large sanding disc

paper. Follow the manufacturers 

recommendations when selecting sandpaper.

Larger sandpaper that extends beyond the sanding

pad presents a laceration hazard and may cause 

snagging or kickback, or may cause the disc to tear

off. 
3.6 Safety Warnings Specific for Wire 

Brushing Operations: 

a) Be aware that wire bristles are thrown by the

brush even during ordinary operation. Do not 

overstress the wires by applying excessive

load to the brush. Wire bristles can easily

penetrate light clothing and/or skin. 

b) If a guard is recommended for wire brushing,

do not allow the wire wheel or brush to come

into contact with the guard. The wire wheel or

brush may expand in diameter due to the work load 

and centrifugal forces. 
3.7 Additional Safety Instructions:

WARNING – Always wear protective 

goggles.

Use elastic cushioning layers if they have been 

supplied with the grinding media and if required.

Observe the specifications of the tool or accessory 

manufacturer! Protect discs from grease or impact!

Grinding wheels must be stored and handled with 

care in accordance with the manufacturer's 

instructions.

Never use cut-off wheels for roughing work! Do not 

apply pressure to the side of cut-off wheels.

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 3 and the 12. Technical Specifications 

chapter for more information on the spindle length 

and thread.

It is recommended to use a stationary extraction 

system and to place a ground fault circuit interrupter 

(GFCI) downstream. If the angle grinder is shut 

down via the GFCI, it must be checked and cleaned. 

See the 8. Cleaning chapter for more information on 

cleaning the motor.

Damaged, eccentric or vibrating tools must not be 

used.

Avoid damage to gas or water pipes, electrical 

cables and load-bearing walls (building structure).

Pull the plug out of the socket before making any 

adjustments, converting or servicing the machine.

A damaged or cracked additional handle must be 

replaced. Never operate the machine with a 

defective additional handle.

A damaged or cracked safety guard must be 

replaced. Never operate a machine with a defective 

safety guard.

This power tool is not suitable for polishing work. 

Improper use of the machine will void the warranty! 

The motor may overheat and damage the electric 

power tool. We recommend using our angle 

polisher for polishing work.

Secure small workpieces, for example by clamping 

them in a vice.

Reducing dust exposure:

WARNING - Some dust created by power 

sanding, sawing, grinding, drilling, and other 

construction activities contains chemicals known to 

cause cancer, birth defects or other reproductive 

harm. Some examples of these chemicals are:

- Lead from lead-based paints,

- Crystalline silica from bricks and cement and 

other masonry products, and

- Arsenic and chromium from chemically treated 

lumber.

Your risk from these exposures varies, depending 

on how often you do this type of work. To reduce 

your exposure to these chemicals: work in a well-

ventilated area, and work with approved safety 

equipment, such as those dust masks that are 

specially designed to filter out microscopic 

particles.

This also applies to dust from other materials such 

as some timber types (like oak or beech dust), 

metals, asbestos. Other known diseases are e.g. 

allergic reactions, respiratory diseases. Do not let 

dust enter the body.

Observe the relevant guidelines and national 

regulations for your material, staff, application and 

place of application (e.g. occupational health and 

safety regulations, disposal).

Collect the particles generated at the source, avoid 

deposits in the surrounding area. 

Use suitable accessories for special work. In this 

way, fewer 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 towards yourself or nearby 

persons or towards dust deposits,

- use an extraction unit and/or air purifiers,

- ensure good ventilation of the workplace and keep 

it clean using a vacuum cleaner. Sweeping or

blowing stirs up dust.

- Vacuum or wash protective clothing. Do not blow, 

beat or brush protective gear.
