SIDE BRUSH:
The side brush, Part. 1 Fig. 4 , acts as a dust and waste conveyor. Its purpose is to clean edges, corners and profiles. After cleaning, this
must be disengaged (raised) to prevent raising dust and because the cleaning effect of the side brush is inferior to that of the central
brush. A left side brush is also available as an optional feature.
CENTRAL BRUSH:
The central brush Part. 2 Fig. 4 is the main machine component for loading the dust and waste into the collection bin. It is available in
various degrees of hardness and bristle types, depending on the type of material to be collected up and on the type of floor. It is height
adjustable in case of wear (
See Chapter 13 ).
IMPORTANT: do not pick up cords, wires, packaging straps, sticks, etc., longer than 25 cm as these could wrap around the centre and side
brushes and damage them.
FILTER SYSTEM:
During operation, the filter system ensures that the machine does not raise dust in the surrounding areas. It consists of six cartridge filters
Part. 1 Fig. 5 . The filter system can be disengaged by pulling knob Part. 1 , seen in Fig. 6 .
IMPORTANT: Disengage the filter system when passing with the machine over wet or very damp areas to prevent dampening and therefore
deteriorating the paper filters.
DUST SEALS:
See Part. 4 Fig. 6 . These seals surround the central brush and are very important for ensuring good machine operation, making possible as
they do the suction effect. Frequently check to make sure they are in good condition.
COLLECTION BIN:
The container or collection bin Part. 1 Fig. 7 , made of resistant plastic, holds all the material picked up by the central brush and the filter
dust. It can be easily removed thanks to a wheeled frame Part. 2 Fig. 7 .
IMPORTANT: container emptying must always be done with the motor shut off. Wear gloves and possibly a face mask to protect the
airways from dust (always present in this operation).

in forward position, the machine moves forward when the pedal is pressed. When switch is positioned in reverse, the machine reverses.
For safety reasons, the reverse speed of the machine is very low. When the switch is in central position, the machine moves neither
forward not in reverse.
SIDE BRUSH ENGAGEMENT LEVER:
The engagement lever Part. 1 Fig. 10 makes it possible to lower the brush from the driving seat. Remember that the side brush must only
