Replacing filter bag or filter element
1. Open the retaining clamps and remove the upper section of the vacuum cleaner.
2. Carefully remove the filter bag connection from the inlet fitting and insert a new filter bag
in the dirt tank. Press the bush of the new filter bag firmly on to the inlet fitting (dispose of
the filter bag in accordance with legal regulations).
3. Turn the filter holder anticlockwise and remove the filter element. Dispose of the used
filter element in accordance with legal regulations. Insert the new filter element. Fit the
filter holder and turn it clockwise to secure it.
4. Clean the rim of the tank and the seals in the intermediate ring and the upper section of
the cleaner before refitting them. Close the retaining clamps.
AutoClean function
The extraction unit is equipped with an automatic filter cleaning system. A frequent cleaning
cycle will automatically run during operation to ensure that suction performance is always at
its best. If suction performance decreases, a manually filter cleaning operation is
recommended:
1. Turn the switch (7) to position
„I“ and let the machine operate at full speed (8).
2. Close the extraction hose opening with the palm of your hand for approx. 10 seconds.
3. If suction power is still reduced take out the filter and clean mechanically or replace filter.
For certain operations it is recommended to turn off the AutoClean function by turning the
switch (7) to the respective stop position.
Picking up dry substances
The appliance is equipped with a pre-installed filter element. Before picking up dry
substances, always ensure that a filter bag is inserted in the tank. After picking up liquids, the
filter element is wet. A damp filter element clogs more quickly when dry substances are
picked up. For this reason the filter element should be washed and dried or replaced by a dry
element before dry substances are picked up.
Picking up liquids
Before liquids are picked up, always remove the filter bag. If foam appears, stop work
immediately and empty the tank.
1. Open the retaining clamps and remove the upper section of the extraction unit.
2. Turn the filter holder anticlockwise and remove it. Insert a separate filter element for
picking up liquids. Fit the filter holder and turn it clockwise to secure it.
3. Remove the used filter bag.
