MACHINE PREPARATION 

 

 

 

 

WARNING: The dosing system is suitable for frequent maintenance cleaning. 
Acid or alkaline maintenance detergent tank be used with pH values between 4 
and 10 and that do not contain: oxidising agents, chlorine or bromine, 
formaldehyde, mineral solvents. 
The detergents used must be suitable for use with scrubbing machines. 
Wash the circuit with water after use if the system is not used daily. The 
system is excludable. In case of sporadic use of detergents with pH between 
1-3 or 11-14, use the scrubbing machine in the traditional way by adding the 
detergent in the clean water tank and excluding the dosing circuit. 

 

 

 

22.   ASSEMBLING THE SPLASH GUARD RUBBERS (BRUSH HEADS WITH DISC BRUSHES) 

For packaging reasons, the splash guard rubbers are supplied disassembled from the machine. Use 
the parking brake handle (1) to stop the machine. Unthread the pin (3) from its seat on the 
handlebars, and insert it in the holes of the handle (2) to prevent the lever slipping. 
Raise the brush head by means of the pedal or key (AU version). 
Turn the key anticlockwise (to "0FF") and remove it from the start-up switch (4). 
To connect the rubber, remove the rubber-pressing blades and unthread the spring hook (5) from the 
connection screw. Wind the rubber all around the brush head, inserting the brush head fixing screw in 
the central hole. Reattach the blades, starting from the centre of the brush head. 
Be careful not to invert the right blade with the left one, as they are not the same. 

 

 

23.   ASSEMBLING THE BRUSH (BRUSH HEADS WITH DISC BRUSHES) 

1.

 

Use the parking brake handle (1) to stop the machine. Unthread the pin (3) from its seat on the 

handlebars, and insert it in the holes of the handle (2) to prevent the lever slipping. 

2.

 

Raise the brush head by means of the pedal or key (AU version). 

3.

 

Turn the key anticlockwise (to "0FF") and remove it from the start-up switch (4). 

4.

 

With the brush head up, place the brushes into the plate housing beneath the brush head, turning 

the brushes until the three pins enter the niches in the plate itself; turn until the pin is pushed 
towards the coupling spring and is locked into place. The figure shows the rotation direction for 
coupling the right-hand brush; for the left-hand one, rotate in the opposite direction.  

 

 

ATTENTION: during this operation, check there are no people or objects 
near the brushes 
ATTENTION:
 this operation must be carried out wearing gloves to protect 
your hands 

 

 

 

You are advised to invert the right and left-hand brushes every day. If the brushes are not new 
however, and have deformed bristles, it is better to reassemble them in the same position (the right-
hand one on the right, and the left-hand one on the left), to prevent the different inclination of the 
bristles producing an overload on the brush motor as well as excessive vibrations.
