be cut or become stuck and your hand or arm 

could be drawn into the rotating parts.

l.) 

Never set the machine down until the tool has 

stopped completely. 

Turning tools can catch on 

the storage surface, causing you to lose control of 

the machine.

m.) 

Never allow the machine to operate while car-

rying it at your side. 

The rotating tool can catch 

on your clothing by accident and cause serious 

cutting injuries.

n.) 

Clean the air vent slits on your machine on a 

regular basis. 

The cooling air fan sucks the dust 

into the machine and excessive deposits of metal 

dust can result in electrical hazards.

o.) 

Never operate the machine near combustible 

materials. 

Sparks can ignite these materials.

p.) 

Never use tools that have to be liquid-cooled. 

Water and other liquid coolants can cause poten

-

tially fatal electric shocks.

Cause and prevention of kickbacks

A kickback is a sudden reaction to jamming or catch-

ing  of  a  rotating  disc,  a  support  plate,  a  brush  or 

other accessory. Jamming or catching results in a 

rapid standstill of the rotating accessory, whereby, as 

a counter-reaction, an out-of-control machine is ac-

celerated around the jamming point in a direction of 

rotation opposed to the accessory. If, for example, a 

sanding disc is jammed or caught by the workpiece, 

the disc circumference can dig into the workpiece 

surface  at  the  jamming  point,  causing  the  disc  to 

be expelled. The disc can either fly towards or away 

from the user, depending on the direction of rotation 

of the disc at the jamming point. This can also cause 

sanding discs to break. A kickback is the result of 

misuse of the machine and/or incorrect method of 

work or operation and can be avoided by closely ob

-

serving the following precautionary measures.

a.) 

Always hold the machine firmly and position 

your body and arms such that you can con-

trol any kickback force. 

Always use the auxiliary 

handle, if included in the delivery, to ensure opti

-

mum  control  over  kickbacks  or  reaction  torques 

during start-up. The user can control reaction tor

-

ques or kickbacks if suitable precautionary meas

-

ures are taken.

b.) 

Never place your hands near rotating tools. 

Tools can kick back over your hand.

c.) 

Never position your body in the area in which 

the machine moves in the event of a kickback. 

A kickback accelerates the machine in the direc-

tion of rotation opposed to the disc at the jamming 

point.

d.) 

Take extra care when working in corners, on 

sharp edges, etc. 

Avoid kickbacks and prevent 

the tool from seizing. Corners, sharp edges or a 

jump back tend to cause the rotating tool to catch, 

thus leading to a loss of control or a kickback.

tion.

d.) 

The permissible rotational speed of the ac-

cessory must be at least as high as the maxi-

mum speed specified on the machine. 

Acces-

sories that rotate faster than the permissible level 

can rupture.

e.) 

The outside diameter and the thickness of ac-

cessories  must  be  within  the  specified  size 

range of the machine. 

Accessories with incor-

rect  dimensions  cannot  be  sufficiently  protected 

or controlled.

f.) 

Threaded mounting of accessories must 

match the grinder spindle thread. For acces-

sories 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 damaged accessories. Before use, 

always check accessories such as sanding 

pads for nicks or cracks and check support 

plates for cracks and excessive wear. Every 

time the machine is dropped, check the ma-

chine and accessories for damage, or install 

undamaged accessories. Following the check 

and assembly of accessories, ensure that all 

persons are beyond the rotating range of the 

tool and run the machine for one minute at 

maximum speed. 

Damage accessories usually 

break completely during this test time.

h.) 

Wear personal protective equipment. De-

pending on the application, use a shield or 

protective goggles. If practical, wear a breath-

ing mask, ear protectors, safety gloves and a 

work apron suitable to protect against impact 

or small sanding or workpiece parts. 

The pro

-

tective goggles must be capable of blocking fly

-

ing debris caused by the various work operations. 

The  breathing  mask  or  device  must  be  capable 

of fi ltering particles generated during work. Con

-

tinuous exposure to loud noise can cause loss of 

hearing.

i.) 

Ensure that persons standing near the ma-

chine are at a safe distance from the work 

area. All persons in the work area must wear 

personal protective equipment. 

Parts  of  the 

workpiece or broken accessories can fly off and 

cause injury outside the immediate work area.

j.) 

Always hold the machine by the insulated han-

dles if you intend to perform work that may 

pose a risk of cutting into hidden power ca-

bles or your own machine cable. 

Contact with 

live cables transfers an electric current to metallic 

machine components and causes electric shocks.

k.) 

Keep the power cable away from rotating 

parts. 

If you lose control, the power cable could
