e) The external diameter and thickness of the
accessory tool used must comply with the
dimensions of the power tool. Incorrectly dimen-
sioned accessory tools cannot be sufficiently
shielded or controlled.
f) The thread of the accessories must match the
thread of the grinding spindle. For accessories
mounted by means of a flange, the bore of
the accessory must match the diameter of the
flange. Accessories that do not fit on the appli-
ance will run unevenly, vibrate too much and
this may result in loss of control of the unit.
g) Never use damaged accessory tools. Check
accessory tools such as grinding discs before
each use for chips or cracks, grinding plates
for cracks, wearing or excessive wear and
tear and wire brushes for loose or broken
wires. If the power tool or the accessory tool
in use is dropped, check to see if it is dam-
aged or use an undamaged accessory tool.
Once you have checked and inserted the
accessory tool, ensure that you and any other
people in the vicinity remain outside of the
level of the rotating accessory tool and allow
the power tool to rotate at maximum speed
for one minute. Damaged accessory tools
usually break during this test period.
h) 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 a special
apron to protect you from grindings and
material particles. Eyes should be protected
from flying debris that may be caused during
certain applications. A dust or respiratory mask
must filter the dust generated during use. If you
are exposed to loud noise for any length of
time, you can suffer a hearing loss.

i) Ensure that other people remain at a safe
distance from 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.
j) Never remove the power tool before the
accessory tool has come to a complete stop.
The rotating accessory tool could come into
contact with the surface and cause you to lose
control of the power tool.
k) Do not leave the power tool running whilst
carrying it. Accidental contact between your
clothing and the rotating accessory tool could
cause your clothing to get caught and the
accessory tool to penetrate a part of your body.
l) Clean the ventilation slits in your power tool
regularly. The motor fan draws dust into the
housing and the accumulation of a large
amount of metal dust can cause electrical haz-
ards.
m) Do not use the power tool near flammable
materials. Sparks can ignite such materials.
n) Do not use accessory tools that require liquid
coolant. The use of water or other liquid coolants
may lead to an electric shock.
Kickback and corresponding safety
instructions
Kickback is a sudden reaction caused when a
rotating accessory tool, e.g. grinding disc, grinding
plate, wire brush, etc., catches or blocks. Catching
or blocking leads to an abrupt stop of the rotating
accessory tool. If this happens, an uncontrolled
power tool turns rapidly against the direction of
rotation of the accessory tool caught in the block-
age.
If, for example, a grinding disc catches or jams, the
edge of the grinding disc that is projecting into the
workpiece can get caught and break off the grind-
ing disc or cause a kickback. The grinding disc can
then fly in the direction of the operator or away
from them, depending on the direction of rotation
of the disc at the blockage. This can also break
grinding discs.
