●For the subsequent dry suction phase, use a dry ilter. In
case of frequent changes between dry and wet suction-
ing, we recommend using a second ilter set, preferably
polyester ilter cassettes.
5.3 Cleaning the ilter.
The suction unit is itted with an electro-magnetic ilter cleaning
device which can shake off any dust adhered to the folded ilter
cassettes.
5.3.1 Manual cleaning.
The vibration function (switch setting R or RA /switch ②a) should
be activated at the latest when the volume low display ②c
(warning lamp) lights up or when the warning signal sounds or
when the suction output sinks.
5.3.2 Automatic cleaning (automatic vibration).
Filter cleaning is performed (switch setting RA/switch ②a)
automatically during the next working break when the minimum
volume low level is reached.
5.4 Emptying the tank.
Only permitted with dusts with AGW's > 1mg/m³. Switch off ②a,
disconnect plug ⑥, open snap locks ⑨. Take top section ① and
suction hose from the tank ①. Empty the tank.
5.5 Paper ilter bag.
To insert or remove the ilter bag/emptying bag, remove the top
section ①).
To do this, open the side locks ⑨. Only use the paper ilter bag
for dry suctioning.
5.5.1 Inserting the paper ilter bag.
●25 and 50 litre tank Push the lange over the suction
opening
Operating the slide valve:
Push the slide valve from inside to the outside ①, turn by 180°
② (see marking ④) and press from outside through the suction
pipes to the inside again ③.
5.5.2 Exchanging the paper ilter bag
Carefully pull the lange from the suction connections and close
the lange.
Turn on the motor before putting down to ensure that any falling
suspended dust can be suctioned (refer to the graph page 4).
Dispose of the vacuumed material as per the statutory regula-
tions.
6 Cleaning.
Clean the tank and accessories with water. Wipe the top
section ① with a damp cloth. Allow the tank and the accessories
to dry.
7 Servicing.
If the suction output of the unit decreases and is not improved
after the ilter cassettes ⑫ are cleaned, (assuming the tank ⑦ is
empty and the paper ilter bag ⑭ has been exchanged), then it is
time to exchange the ilter cassettes ⑫.
Apply the vibration function to the ilter cassettes ⑫ again before
exchanging them. Use a coin or another similar object to turn the
catch⑤ on the locking bar ④ 90° in an anticlockwise direction
and then press the locking bar ④ backwards. Fold up the hood
and lift out the ilter cassettes ⑫. Immediately seal the removed
ilter cassettes in a dust-proof plastic bag and dispose of as per
the statutory regulations. Insert new ilter cassettes. Fold down
the hood again and exert a little pressure to click it back into
position.
If the motor protection ilter ⑬ is soiled, this is
an indication that the ilter cassettes are
defective. Please exchange both ilter cassettes.
Wash out the motor protection ilter under
running water, dry and re-insert.
Note!
Regularly clean the water level sensors ① and examine them for
signs of damage.
