g) Grinding discs and flanges must fit precisely
onto the grinding spindle of your power tool.
Accessory tools which do not fit precisely on the
grinding spindle of the power tool will rotate
unevenly, vibrate severely and can lead to a
loss of control.
h) Do not use damaged grinding discs. Check
the grinding discs before each use for chips
and cracks. If the power tool or grinding disc
is dropped, check to see if either are
damaged or use an undamaged grinding
disc. After checking and inserting the
grinding disc, ensure that you and any other
people in the vicinity remain outside of the
range of the rotating grinding disc and allow
the tool to rotate at maximum speed for one
minute. Damaged grinding discs usually break
during this test period.
i) Wear personal protective equipment.
Depending on the application, ensure that
you use full face protection, eye protection or
goggles. If required, use a dust mask, ear
protectors, protective gloves or special apron
to protect you from grindings and material
particles. The eye protection must be worn to
protect you against flying debris, which may be
caused by the various applications. Dust or filter
masks must be used to filter any dust created by
the application. If you are exposed to loud
noise for any length of time, you can suffer a
hearing loss.
j) Ensure that other people remain at a safe
distance to your workspace. Anyone who
enters the workspace must wear personal
protective equipment. Fragments of the work-
piece or broken accessory tools can fly off and
cause injury – even outside the immediate
working area.

k) Keep the power cable away from any
rotating accessories. If you lose control of the
appliance, the connecting cable may get cut or
caught and your hand or arm could get caught
in the rotating accessory tool.
l) Clean the ventilation slits in your power tool
regularly. The engine fan draws dust into the
housing and a strong accumulation can cause
electrical hazards.
m) Do not use the power tool near flammable
materials. Do not use the electrical appliance
if it is placed on a flammable surface such as
wood. Sparks can ignite such materials.
n) Do not use any attachment parts that require
liquid coolant. The use of water or other liquid
coolants may lead to an electric shock.
2) Kickback and corresponding
safety instructions
Kickback is a sudden reaction caused when a
rotating cutting disc catches or jams. Catching or
jamming causes the rotating accessory tool to stop
abruptly. This results in an uncontrolled cutting
grinding tool being accelerated upwards towards
the operator.
If, for example, a cutting disc catches or jams, the
edge of the cutting disc that is projecting into the
workpiece can get caught and break off the cutting
disc or cause a kickback. This can also break
cutting discs.
A kickback is caused by improper or incorrect use
of the power tool. This can be avoided by taking
proper precautions as given below.
a) Hold the power tool firmly in both hands and
position your body and arms so that they can
absorb the kickback forces. By taking
adequate precautions, the operator can stay in
control of the kickback and reaction torques.
b) Avoid the area in front of and behind the
rotating cutting disc. In cases of kickback, an
uncontrolled cutting grinding tool is driven
upwards towards the operator.
