Check the condition of the flaps every 40/70 hours. Damage or inefficiency of the flaps jeopardises the performance of the
machine in terms of cleaning quality, Detail 4 Fig. 6 .
IMPORTANT: To replace the side flaps, make sure that their lower edge is 2-3 mm from the ground.
SIDE BRUSH:
Detail 1 Fig. 9
. Keep raised from the ground when not in use to avoid raising dust unnecessarily. Keep raised from the
ground when the machine is not in use and make sure it does not come into contact with other objects which could bend it
making it unserviceable.
CENTRE BRUSH:
To clean the centre brush.
The following implements are necessary for carrying out this operation: heavy duty gloves, breathing mask, pliers, scissors
Check the condition of the central brush every 50/80 running hours, or more frequently if the machine is used for particularly
heavy duties. To gain visual access to the central brush, remove the refuse container (
Detail A Fig. 1 ) and tip the machine as
shown in Fig. 9 , by pressing down the handle.
If any ropes, wires or other refuse of this type has been inadvertently collected up, wear the heavy duty gloves and the
protective mask to eliminate any refuse that has been wound in the brush.

 Loosen the bolt Detail 1 Fig.10 in the slot at the front
 Tighten bolt Detail 2 Fig.10 until the three bolts Detail 1, 2 and 3 Fig.10 make contact
 If the brush is too flat on the ground, loosen bolt Detail 2 and tighten bolt Detail 1 .
N.B.: To ensure the centre brush is correctly adjusted, measure its " Track " as follows:

After making adjustments, start the machine up and, without moving either forwards or backwards, leave it standing in
the same place for at least 10 / 15 sec. with the centre brush lowered.
 Turn off the motor, raise the centre brush and move the machine forwards manually until the mark left by the rotation
centre brush on the floor is visible, as shown in
Fig. 11 .
N.B.: The width of the track must not be under 3 cm.
FORWARD REGULATION:
If a machine with mechanical forward drive has lost power, regulate the forward drive as follows:
Loosen bolt Detail 1 Fig. 12 , move the driving wheel Detail 3 closer to the hub of the driving pulley Detail 4
and unscrew the threaded adjusting screw Detail 2 Fig.12 as required.
IMPORTANT: After regulation the wheel Detail 3 must be as close as possible to the driving pulley Detail 4
WITHOUT ACTUALLY TOUCHING IT.
REFUSE CONTAINER:
To carry out this operation, with the machine off, the following articles are necessary: heavy duty gloves , detergent.
Every 50-60 working hours, or more often if the machine is used for particular heavy duties, the container must be washed to
avoid the formation of un-hygienic conditions which could be dangerous because of the high concentrations of bacteria.
