Only for EU countries
Due to the presence of hazardous compo-
nents in the equipment, used electrical and
electronic equipment may have a negative
impact on the environment and human health.
Do not dispose of electrical and electronic
appliances with household waste!
In accordance with the European Directive on
waste electrical and electronic equipment and
its adaptation to national law, used electrical and
electronic equipment should be collected sepa-
rately and delivered to a separate collection point
for municipal waste, operating in accordance with
the environmental protection regulations.
This is indicated by the symbol of the crossed-
out wheeled bin placed on the equipment.
Intended use
The tool is intended for grinding, sanding, wire brush-
ing, hole cutting and cutting of metal and stone materi-
als without the use of water.
Power supply
The tool should be connected only to a power supply of
the same voltage as indicated on the nameplate, and
can only be operated on single-phase AC supply. They
are double-insulated and can, therefore, also be used
from sockets without earth wire.
For public low-voltage distribution
systems of between 220 V and 250 V
Switching operations of electric apparatus cause volt-
age uctuations. The operation of this device under
unfavorable mains conditions can have adverse e󰀨ects
to the operation of other equipment. With a mains
impedance equal or less than 0.27 Ohms it can be pre-
sumed that there will be no negative e󰀨ects. The mains
socket used for this device must be protected with a
fuse or protective circuit breaker having slow tripping
characteristics.
