ventilation at the location where
the device is to be disassem-
bled, for cleaning the mainte-
nance surface and to ensure
adequate protection for the per-
sonnel. ● The exterior of the de-
vice should be detoxified by
vacuuming and wiped clean, or
treated with sealant before be-
ing removed from the hazardous
area. All unit parts must be re-
garded as contaminated when
they are taken from the hazard-
ous area. Suitable measures
must be taken to prevent distri-
bution of the dust. ● All contami-
nated objects resulting from
maintenance and repair work
that cannot be satisfactorily
cleaned must be correctly dis-
posed of. Such objects must be
disposed of in sealed bags in ac-
cordance with the applicable
regulations for the disposal of
this type of waste. ● Dust class-
es M and H only: Close the suc-
tion opening with the plug when
transporting and servicing the
device. ● Dust class H only: The
effectiveness of the filtration of
the device can be tested by the
test method as specified in EN
60 335-2-69 22.AA.201.2. This
test must be carried out at least
annually or more frequently if
specified in national require-
ments. If the test result is nega-
tive, repeat the test with a new
flat fold filter.
WARNING ● Safety devices
providing hazard protection
must be checked for correct
safety-related functionality at
least annually by the manufac-
turer or an appropriately instruc-
tion person, e.g. absence of
leaks, filter damage, functionali-
ty of the monitoring devices
(dust classes M and H only).
Devices with rotating brushes
DANGER ● Risk of electric
shock. Never run over the mains
connection or the extension ca-
ble with the rotating brushes of
the suction head.
CAUTION ● Unsuitable
brushes endanger your safety.
Only use the brushes supplied
with the device or brushes rec-
ommended in the operating in-
structions.
Devices with pneumatic tyres
CAUTION ● Never exceed
the maximum permissible tyre
filling pressure. The tyre filling
pressure needs to be read on
the tyre and if necessary on the
wheel rim. If these values differ,
use the smaller value. ● Make
sure that the pressure reducer is
set correctly on the compressor
before setting the tyre filling
pressure. ● In case of devices
with screw-in wheel rims: Make
sure that all wheel rim bolts are
tightened securely before set-
ting the tyre filling pressure.
