The extraction unit GU1 is suitable for dust class L.
5.9 Intended use
WARNING!
In the event of improper use, the extraction unit
will endanger personnel,

the extraction unit and other property of the operating company and

the functionality of the extraction unit may be compromised.

The extraction with blower and cyclone separator has been designed and built for the extraction
of air pollutant substances on manually operated machines for tools with geometrically non-
determined blade.
It is forbidden to use the extraction unit when machining with non-water-soluble or water-solu-
ble cooling lubricants. The device is not suitable for the extraction of mixtures of combustible
dusts with fluids.
The extraction unit must only be installed and operated in a dry and well-ventilated areas.
The defined conditions of use and performance data must not be changed.
The extraction unit must neither be renovated nor modified in any other way.
Dust category L
(Low risk according to the definition of standard EN 60335-2-69). According to the EN standard,
the extraction unit is approved for dust category L and thus, for the extraction of dry, non-com-
bustible and dust hazardous to health with occupational exposure limit values (German AGW)
of > 1mg/m³. The clean air is emitted back to the location.
Dust category M
(Medium risk according to the definition of standard EN 60335-2-69). The extraction unit is suit-
able for the extraction of dry, non-flammable dust hazardous to health where the occupational
exposure limit value is higher than 0.1 mg/m³.
Dust category H
(High risk according to the definition of standard EN 60335-2-69). The extraction unit is suita-
ble for the extraction of dry, non-flammable dust hazardous to health for all occupational expo-
sure limit values as well as for non-flammable dust with carcinogenic substances. The clean air
is emitted back to the location.
Use in dust areas with potentially explosive atmosphere (Type 22)
Safety-related, extraction units with the supplement "Type 22" are suitable for extracting flam-
mable, dry non-electrically conductive dusts in Zone 22. Exceptions are dusts with extremely
low minimum ignition energy (MIE < 1mJ). Use with these dusts requires a case-related safety
assessment and, where applicable. further measures.
Safety-related, the extraction unit is not suitable for extracting potentially explosive substances
in line with §1 Explosives Act. Do not extract hot gases, ignition sources of any type, sparks
generated mechanically or electrostatically charged materials.
If the extraction unit is used other than as specified above, without the permission of the com-
pany Optimum Maschinen Germany GmbH, the machine is no longer used properly.
We will not be held liable for any damages resulting from any operation which is not in accord-
ance with the intended use.
We expressly point out that the guarantee will expire, if any constructive, technical or proce-
dural changes are not performed by the company Optimum Maschinen Germany GmbH. It is
also part of the intended use that you
