s) Do not use parts or accessories not designed to work
with this device, unless they have been indicated by
the manufacturer as compatible.
t) The rated speed of the accessory must be at least
equal to the maximum speed of the device, otherwise
accessories that rotate faster than the rated speed
may be destroyed.
u) Parameters of used accessories (discs, sandpaper)
must be in accordance with the technical parameters
indicated in the table; otherwise the device may not
be properly secured and controlled.
v) Attaching the accessories must be compatible with
the device's mounting hardware.
w) Accessories not suited to the device's mounting
hardware may lose their stability, over-vibrate, and
the control over them may be lost.
x) Do not use accessories which are damaged. Before
every use, check their condition in terms of chips,
cracks, tears or excessive wear.
y) Should you drop the device, check it for damage.
After inspection and replacement of damaged
elements, set the device securely with respect to the
user and the third parties so that all are away from the
rotating elements. Turn on the device at the highest
speed and allow continuous operation for about 1
minute. Damaged parts during this procedure ought
to fall apart.
z) Hold the device touching only the insulated handle
surfaces. It is possible you may come across hidden
wiring or hit your own power cord while working.
Contact with the power cord may cause electric shock.
aa) Keep the power cord away from rotating parts. If you
lose control over the device, the cord may be cut or
caught and a limb may be pulled into the rotating
accessories.
bb) Do not put the device away until it stops working and
is switched off. Rotating elements may come into
contact with the surface and rip out the equipment
from the user's grip.
cc) Do not operate the device when worn on the body.
Accidental contact of rotating accessories with clothes
you wear with may cause the rotating elements come
dangerously close to your body.
dd) Do not use accessories that require the use of cooling
substances. The use of water or liquid coolant may
cause electric shock.
ee) Hold the device firmly so that you can resist the force
in the event of a kickback. Use the auxiliary handle, if
available, to obtain maximum control over kickback or
torque during start-up.
ff) Keep away from rotating parts, those parts may
bounce towards your body.
gg) Do not position yourself body in the direction in
which the kickback can occur. The kickback will direct
the device in the direction opposite to the rotation.
hh) Pay special attention when working corners or sharp
edges. Avoid locking and contact with random objects
while working. It may result in losing control over the
device.
ATTENTION! Despite the safe design of the device
and its protective features, and despite the use of
additional elements protecting the operator, there
is still a slight risk of accident or injury when using
the device. Stay alert and use common sense when
using the device.

the type of surface being worked on.
• When finishing work, it is recommended to hold the
device against the sanded surface to collect all the
dust.
