d) Nominal rpm of accessories must be
at least equal to the maximum rpm,
stated on the tool. Accessories that op-
erate at higher rpm than are the nominal
rpm, may break and pull apart.
e) Outer diameter and thickness of your
accessories must be within the limits
of nominal range for your electrome-
chanical tool. Accessories of incorrect
dimensions cannot be either protected
enough or controlled properly.
f) Clamping dimensions of disks, fl anges,
supporting plates or any other acces-
sories must be suitable for fi xing to
the tool spindle. Accessories with clamp-
ing holes which do not correspond with the
mounting dimensions of electromechani-
cal tool will be unbalanced, may vibrate
excessively and cause loss of control.
g) Do not use damaged accessories.
Check the accessories prior to each
use: check the grinding wheels for
chips and cracks, check the sup-
porting plates for cracks, ripping
or excessive wear, check the wire
brushes for loose or cracked wires. If
accessories or tool fell down, check
the damage or mount undamaged
accessories. After the accessories
is checked and mounted, you and
also bystanders stand to be beyond
the level of rotating accessories and
leave the tools run free at highest
rpm for one minute. During this trial
time damaged accessories usually rips
apart or disintegrates.
h) Use personal protective means. De-
pending on use, use facial shield and
safety protective goggles. If appro-
priate, use dust mask, ear protec-
tors, gloves and work apron, capa-
ble of capturing small fragments of
abrasive material or workpiece. Eye
protection must be capable of capturing
fragment impact created during various
work activities. Dust mask or respirator
must be capable of fi ltering off particles
created during your work. Long-term
exposure to noise of high intensity may
cause hearing loss.

i) Keep bystanders in safe distance from
the working space. Everybody enter-
ing the working space must wear per-
sonal protective aids. Any fragments of
the workpiece or of damaged accessories
may fl y off and cause injury even out of
the proximate working space.
j) During work, when the cutting tool can
touch hidden circuit or its own mobile
service line, hold the tool only at the
points of insulated gripping surface.
When in contact with "living" conductor,
the cutting tool may make the accessible
metal parts of the tool "living", thus caus-
ing injury of the user by electric current.
k) Place the mobile service line out of the
reach of the rotating tool. If you loose
control, the mobile supply can get cut
cross or reground and your hand or arm
may be pulled inside the rotating tool.
l) Never lay any electromechanical
tools until the tool stops. Rotating tool
can get captured by the surface and pull
the tool up off your control.
m) Never turn the electromechanical
tool on your side during handling.
Accidental contact with the rotating tool
may lock your clothes and draw the tool
up to your body.
n) Clean the vent holes of the tool regu-
larly. The engine fan draws dust inside
the cabinet and excessive accumulation of
metal dust may cause electric hazard.
o) Do not work with electromechanical
tool near fl ammable materials. It may
cause ignition of these materials due to
sparks.
p) Do not use accessories that require
cooling with fl uid. Use of water or any
other cooling fl uids may cause injury or
death due to electric current.

for all types of works
Kickback and related warning
Kickback is accidental reaction to gripping or
jamming of rotating disk, supporting plate,
brush or any other instrument. Gripping or
jamming may cause pull-up of the rotating
tool which subsequently causes motion of
