Adjusting the side brushes
! WARNING!
Never operate the machine without the side brushes installed.
The side brushes direct dirt and debris towards the centre of the machine. The most efcient height
for this purpose is when the side brushes gently touch the oor. Proceed as follows to increase or
reduce the pressure of the side brushes on the oor, if necessary.
► Lower the side brushes into work position (g. 21).
► Loosen the two locking screws under the brush lifting knob (g. 22).
► Manually move the brush to the required position.
► Tighten the locking screws again (g. 22).
► Return the brushes to idle position.
Replacing/installing the suction lter
! DANGER!
This operation must be performed with the machine switched off and the key removed.
The suction lter makes a major contribution to the efciency of the whole machine.
Its correct maintenance keeps the machine at maximum efciency at all times. If the sweeper begins
to raise dust as it sweeps, check the condition of the suction lter.
The suction lter can be cleaned in two ways.
Semiautomatic lter cleaning:
► This method provides a quick and easy way to keep the suction lter clean and ready for
work. Press and hold the lter shaker button for a number of seconds, then repeat four or
ve times. On Petrol and Diesel versions, shut off suction with the suction control lever
before pressing the lter shaker button.
