Maintenance
Maintenance activities consist in following steps:
●
Periodically, clean the
hood
surface
and the inlet wire mesh of the deposited dust and impu-
rities to provide proper flow of the extracted air. In case of welding dust, rinse the hood ad-
ditionally with the anti-spattering preparation
(
to avoid gluing up the welding
chipping on the
on the hood surface).
●
Undertake the adjustment of its joint system
in case when the extraction arm loses its self-
-supporting properties.
●
Lubricate the swivel every 3 months
using solid grease (lubrication nipple is located in the
swivel flange).
●
After 1 operational year, submit the device
to technical revision and repair / or replace the
the spotted faulty element.
●
Clean the internal surfaces of the extraction segments from the deposited impurities. Fre-
quency of these steps depends on the intensity of use.
Within a period of 3 months, it is
recommended to examine
the pollution state
and
undertake cleaning
when
necessary.

Occupational Health and Safety
Prior to start and use,
it is important to get acquainted with the present Use and Mainte-
nance Manual
.
The ERGO LUX-R extraction arms
will not cause any hazard under the condition that they are
firmly and correctly mounted to the wall or another structural element of the building.
Unsure mounting could
result in an
uncontrolled detachment of the device and would cause se-
rious hazard to personnel / people in the vicinity.
Having completed the work, leave the extraction
arm in the ultimate operational position, in case
when it constitutes obstacle / barrier to personnel, set in into the home position.
Prior to installing check the load carrying capacity of the building structure
.
