Mounting (see figure
Before any work on the device itself, pull the
mains plug.
Unlock the latches 13 and remove the vacuum
top 3.
Vacuuming directly into the container is pos-
sible for materials not harmful to one's health
with or without an exposure limit value
greater than/equal to 1 mg/m
dust category L (until now applicational cate-
gory U).
For dry vacuuming operation, a dust bag 17 (ac-
cessory) should be inserted.
When operating with a dust bag, the folded fil-
ter 18 clogs less fast, the vacuuming perform-
ance is kept up longer and the disposal of dust
becomes easier.
Grasp a new dust bag 17 at the flange. Push it
over the bottom of the connection piece first and
then over the cog on the top. Make sure that the
full length of the dust bag faces against the inner
wall of the container 11. Attach the vacuum top.
Lock the latches 13.
Insert the vacuum hose 10 into the hose con-
nection piece 9 until it is seated firmly or place it
onto the hose connection piece 9 respectively,
and turn it in clockwise direction to the stop.
Insert the extension tubes firmly into each other.
It is recommended to use static-discharging
hoses with a hose Ø of 19 or 35 mm.
If the warning lamp 4 flashes during IS opera-
tion (industrial vacuum cleaner operation) and/
or the alarm sounds during ENT (dedusting)
mode, the folded filters 18 must be cleaned. For
this, set the mode selector switch 6 to the "Elec-
tromagnetic filter cleaning" symbol. The filters
are cleaned for approx. 10 seconds. If the warn-
ing lamp 4 continues to flash and/or the alarm
sounds afterwards, the dust bag 17 must be re-
placed. If the warning lamp 4 still flashes and/or
the alarm still sounds, the vacuum cleaner must
be checked as described in the section "Mal-
functions".
Caution! The machine contains dust which is
harmful to one's health. Emptying and main-
tenance, including the disposal of dust collec-
tion containers, may be carried out only by
specialists. Suitable safety equipment is re-
quired. Do not operate the machine without
the complete filter system.
